Moral Event Horizon



"Tarkin, if ever there was a shred of humanity in you or these twisted creatures of yours, it's dead now. You're at war with life itself."

- Princess Leia Organa, from the Star Wars Radio Dramas, after Grand Moff Tarkin wipes out her home planet.

"Moral Event Horizon", or "MEH" for short, refers to an action by a villain that is so evil that it usually eliminates audience sympathy for the villain and makes it clear that they are unrepentantly evil and will not be redeemed, unless if they themselves are offended by the actions of another villain, or admit themselves that they are beyond redemption.

The scientific fact that nothing can escape a black hole is referred to as the boundary of the region from which no escape is possible and is known as the event horizon, hence the term Moral Event Horizon. A villain who crosses the horizon, or enters the black hole, has no hope of escaping except under extremely rare, extraordinary circumstances.

All Complete Monsters are by definition beyond the Moral Event Horizon. However, crossing the Moral Event Horizon does not necessarily make a villain a true Complete Monster, it only means that they are irredeemably evil. Some villains have or almost crossed the Moral Event Horizon, or done something despicable enough to make the fans believe they did so, only to later redeem completely or partially. A strong example of a Complete Monster would be either a villain who (in addition to having no adequate Freudian Excuse) commits multiple  especially heinous Moral Event Horizon-worthy deeds, or a villain who is exceptionally brutal and evil in nature when crossing the MEH.

However, some villains of this who crossed MEH would die in disgrace and become Damned Souls.

By definition, a character can only cross the Moral Event Horizon once; however, it is possible for a villain to have more than one event as a potential Moral Event Horizon, such as the various adaptations of the Joker and Teridax. Other villains have more than a potential and often leave an impact on the public that they do wicked things all the time and commit Moral Event Horizon acts like a hobby, such as Sir Isaac Ray Peram Westcott, Emperor Palpatine and Emperor Tathagata Killer. These characters are almost invariably Complete Monsters.

IMPORTANT NOTE: Two things that should not added on the list of MEH below:
 * Fanon examples, as this would confuse the reader.
 * Certain flawed actions that done by characters that confirmed not evil nor antagonistic (Franny Robinson grounded her son Wilbur until his death for his mess that also led Lewis present in the future or SpongeBob's ungrateful acts on Gary in spite of his heroic acts for saving him from Puffy Fluffy for examples) won't be ever counted as act of MEH if the said actions not officially put them to the dark side or merely portrayed them as flawed hero.

A Song of Ice And Fire

 * Ramsay Snow: Torturing Theon Greyjoy for pleasure, renaming him "Reek" and making him his passive slave. But above all, castrating him.
 * Joffrey Baratheon: Ordering the beheading of Ned Stark, and torturing Sansa with this throughout the series.
 * Cersei Lannister: If it's not by ordering that Tyrion be arrested for Joffrey's murder, it's the unscrupulous pleasure she receives and makes no effort in hiding when Oberyn is killed and fails to win Tyrion's freedom in the trial by combat.
 * Petyr Baelish: If he crosses it, it's by betraying Ned and helping the Lannisters maintain the Iron Throne (could qualify for almost anyone who refuses to cross the Lannisters when in the position to do so).

After Zuko scolded his father for this years later, Ozai threatened to kill his son with lightning. Otherwise, in the finale, he appoints his daughter Azula as Fire Lord... but seconds later, Ozai tells her that the position is powerless. In comic series Searching, Ozai revealed his sadistic nature to his wife Ursa, when he told that he'll abuse Zuko as if he was son of Ursa's lover Ikem in order to punish her for missing her lover, despite Zuko being Ozai's son and did nothing to deserve this. In either way, Ozai's atrocity against both Zuko and entire world ultimately haunted Zuko in his early days as a Firelord, to the point that he almost ruin both his life and his bond with his allies and friends (especially Aang) out of fear to turned to the dark side as far as Ozai ever did.

Though he failed in this, he managed to temporary had her both in depressed and wheelchaired state as well as responsible for unintentionally created a hallucinogenic entity in Korra's mind as result of scarring her mentally. After being imprisoned, on the other hand, he later regretted his actions after a new dictator started to began her own empire, one of the reaso why  he undone the damage that he caused on Korra as the redemption of his said MEH crossing actions.
 * Kuvira: She first crossed it by attempting to kill Korra after defeating her, then ordered her army to attack after Opal and Jinora intervened.

 * Story Prologue:
 * ​30 Years ago during the first spacequake created by the First Spirit that decimated half of China and Mongolia and killed over 150 million people in just 2 measly minutes. Elliot Woodman was a friend of Isaac Westcott in the past, Elliot was so near of Isaac that he referred to Isaac Westcott as "Ike" and he considered Isaac Westcott as a brother. However, 30 years ago when the First Spirit mysteriously appeared on planet earth, Elliot left the side of Isaac after the First Spirit appeared. The reason Elliot left side of Isaac 30 years ago was so strong and monstrous, that Elliot left the D.E.M Industries and formed Ratatoskr to prevent the insane Isaac's goals. Isaac Westcott became a archenemy of Elliot and had become an enemy of humanity. What caused the apparition of First Spirit and what was the involvement of Isaac and Elliot with the First Spirit is completely unknown. 30 years later, Isaac communicated to Elliot, Isaac tried to call Elliot back to his side, however, Elliot's response was:
 * Sadly, I don’t have such intentions, Ike. I told you that many times 30 years ago......Ike, I do not know if there still "a human" inside you. I may be going blind because of my age, but I see "that Ike" died. There is no more a single piece of love or compassion in you, you is not nothing but "monster", a "thing" without any kindness that only brings evil. You went down in a deep hole without salvation. I created the Ratatoskr to prevent you, Ike, no.....Isaac Ray Peram Westcott! - Elliot Woodman

Dragon Ball

 * Tao Pai Pai: The first Complete Monster of the series who makes a profit out of slaughtering people, whether it's man, woman or child. After killing Bora he then goes on to curb stomp Goku and would have killed him had it not been for his Grandpa's Dragon Ball shielding him from the attack. He then commits his worst act when he forces a tailor to overwork on making a new outfit for him, and then murders him when the tailor asks him to pay for it.

He started as a ruthless mass murderer interested only in power, and crossed many lines by killing or abusing Goku's friends (and his own), Namekians, many innocent people (under Babidi's control) and acting selfish to his friends and family. By redeeming himself after all this, he can be considered as a Karma Houdini. However, all his victims were resurrected (and later when reviving Buu's victims, Vegeta wants to make sure his victims were revived as well), and Vegeta was killed twice, the second time through a heroic sacrifice. Therefore, his crossing of the Moral Event Horizon is very debatable.
 * Broly: He crosses it when he blows up an entire planet that the slaves his father had that they use to live on, and says, "Oops, I did I blow it up?", followed by maniacal laughter.

 * In later seasons, the Mane 6 work their hardest to redeem him. In Keep Calm and Flutter On, he reveals that he had only tortured the ponies out of self-defense, so Fluttershy offers to keep Discord's evil in check. Discord pretended to be Fluttershy's friend, so well that it really worked.
 * In Twilight's Kingdom, he almost crosses the MEH when he betrays all of Equestria when Tirek tempts him to join forces with him.

This was arguably the most depressing moment of the series. Although many feel her true crossing of the Moral Event Horizon occurred in the comics, whose canonocity is up to the fans.
 * King Sombra: He enslaved an entire empire, uses fear on them, presumably killed its previous ruler, and tries to impale Spike, a baby dragon, to get the Crystal Heart, licking his lips as he gets closer to doing so.

 * Tirek: He either crosses it when he banishes Princesses Celestia, Luna, and Cadance to Tartarus, even though they had already given their powers to Twilight, or when he seals Twilight's friends inside a cage, and drains their and Discord's magic, revealing his partnership with Discord to have been a sham.
 * Starlight Glimmer crosses it in the two-part season 5 finale, The Cutie Remark, when she returns to get revenge on the Mane 6 by claiming a spell that could change the past, present and future of Equestria for good, meaning she might also keep the Mane 6 from claiming their cutie marks and start a new and more powerful equal society around Equestria.

 * Sasuke Uchiha: He deserted his homeland to join Orochimaru to become more powerful out of vengeance. He also showed no allegiance to any group, because he defected Konoha, Otogakure and the Akatsuki, when he no longer saw any use in them. He captured Killer B, host of 8-tailed beast that resulting A the Raikage held the vengeful grief which only diminished by revelation that Killer B escape but use his capture as ruse to have fun outside his home village. He attacked all kage because they stand in his way to kill Danzo, showing no respect to their authorities and becoming an international criminal. He also stabbed his most loyal supporter, Karin and left her to die. He also told Sakura Haruno to kill her only to divert her attention from his attempt to kill her. It should be noted that he nearly become a Complete Monster in process, though thanks to his reunion with Itachi Uchiha and confrontation with Kabuto, he question both his error and truth about everything that happened in his life, and after conversation with Orochimaru along with released souls of those whom sealed by Dead Demon Consuming Seal, he eventually chooses to redeemed himself. However he's still an insensitive social Darwinist and a jerk with no respect for his teacher Kakashi only because he no longer has Sharingan. After defeat of Kaguya he decided to execute kages instead of saving them, he declared his revolution against the whole ninja system, becoming a public enemy for the last time, something which prompt Naruto to battle him again. In the end however, Sasuke eventually change his mind and redeem himself completely after realized that Naruto still consider him as his best friend no matter how far he turned to the dark side as much as Itachi did. All in all, Sasuke is one of known MEH crossers that still has a chance for redemption in spite the huge damage that he inflicted during the moments after learning the truth behind Uchiha's downfall. In addition, as he himself aware how far he turned to the dark side, he decided to embarks a long journey for achieving total redemption, especially for redeeming his MEH crossing deeds.

Even after his death and reanimation, he didn't get better.
 * Sasori: He killed the 3rd Kazakage and turned his corpse into a puppet & he also tried to kill his grandmother Chiyo and Sakura Haruno.

 * Kabuto Yakushi: It's revelated he's Orochimaru's spy. He sacrifaces thousands of people to create his reanimated ninja army to support Obito Uchiha in his war.
 * Danzo Shimura: Tricks Hanzo that Yahiko is his enemy and later helps the former to kill the latter in exchange of promoting him to become a Hokage, tricks both Nono & Kabuto Yakushi into becoming Konoha's spies & then made them kill each other, stole Shisui's eye, ordered Itachi to kill the entire Uchiha clan, orders Sai & his brother Shin to kill each other, kills the messenger toad Kosuke so that he cannot tell Naruto about Pain's attack and then gathers his ROOT troops underground without even helping Tsunade defend Konoha hoping he would become Hokage, uses his "6th Hokage" authority to officially declare Sasuke as a wanted criminal, abandons the other 4 Kages to deal with Sasuke & the Zetsu clones & then mocks Itachi during his fight with Sasuke & he also took Karin as a hostage to slow Sasuke down, but she meant nothing to him. Though most of his action supposedly has beneficial consquences by some, these actions are considered despicable due to many casualities.
 * Hidan: He with Kakuzu captured Yugito Nii and helped in extracting her demon from her body, resulting her death. The two of them subsequently slaughtered a temple's worth of monks in order to collect the bounty on the head monk, Chiriku. He also tortures & kills Asuma Sarutobi & then sacrificing his soul to Jashin. He showed no regret in killing Asuma as he physically enjoyed it. Asuma wasn't his first victim. He even tried to kill Shikamaru & mocked Asuma in front of him. Even when having Shikamaru bury him alive, this not stopped him from mocking the latter.
 * Nagato/Pain: He killed Jiraiya and drowned his corpse, althought it can be considered as a self-defence or defence of own city-state from an invader, but nothing can advocate his attack on the Leaf village, it's anihilation and genocide of its populance just to seek for Naruto and his inner demon. He became evil, when he ordered Akatsuki members to capture all jinchuuriki and with them he killed them during extraction of their inner demons. He captured Utakata himself in anime after slaughtering his countrymen ninjas.

Another reason to hate him is Madara somehow successfully keep himself alive as a free undead just as he realized Kabuto undo the summoning dead technique before his soul back to afterlife, and his long-time evil scheme, even if Obito proceed his dirty work before his resurrection, proves disastrous and results many deaths during it's process, includes Naruto's parents'. He even went too far by stealing Kakashi's Mangekyou Sharingan just to cross the other dimension and retrieve his Rinnegan from Obito due to Naruto and Sasuke turned the tide of the battle & even admitting how he planned Rin's death all along.
 * Obito Uchiha: He decided to follow Madara's plan, he caused death of Naruto's parents and massive destruction of the Leaf village by extracting Kurama, he killed Nagato's friends, he knew about Danzo's actions but kept the truth for himself, he manipulated Kisame, Nagato and Sasuke to join him and capture the tailed beasts. He also controled mind of the 4th Mizukage and cruel reputation of the Mist Village was thanks to him.

 * Steven Jacobs - Cared only about profit and little about anyone else's well being. But he truly crossed it when he assisted the police in shooting and killing many of the apes on the Golden Gate Bridge. Despite his death, his damage proved too great: His actions not only drove Koba turned to the dark side, but his involvement with the "ALZ-113" also causes most of mankind's population dies as he unaware that one of his employee, who took one of the vial, unknowingly realize that ALZ-113 became a deadly virus that kill most human population and evolved apes into stronger being.
 * Koba - Though Caesar took him in and treated him as a friend, Koba hated humans, so much that it blinded him and caused him to take villainous actions.

The Simpsons

 * Town of Springfield: (Note: It is not a character but an entire population that crosses the Moral Event Horizon) In "Boys of the Bummer", they mistreated Bart simply over a baseball game and even after Bart tried to commit suicide, they didn't stop abusing him. They later apologized to Bart after Marge called them out on their cruelty.
 * Mr. Burns: In Curse of the Flying Hellfish, he threatens to shoot Bart and then tries to drown him.
 * Sideshow Bob: In Funeral for a Fiend, he tricks everyone in Springfield into turning against Bart by convincing them that Bart lead him to insanity. He then fakes his death, pinpoints it on Bart, and everyone sees Bob die as a legend. However, he finally crossed it when he had his brother lead Bart to the funeral home to be cremated alive.
 * Russ Cargill: Although at first he only wants to prevent Springfield's pollution from spreading, he crosses the line by attempting to destroy Springfield (killing its entire population) with a time bomb.
 * Moe Szyslak: Force drank Homer to near death because he realized that beer is ruining his marriage.
 * Cecil Terwilliger: Attempts to kill his brother Sideshow Bob, Bart and Lisa, and blow up the Springfield dam and flood Springfield, to frame Bob and make off with the money he embezzled.

South Park

 * Eric Cartman: Having Scott Tenorman's parents killed and feeding them to him as chili. This was the most prominent indication of his progression from a bratty, selfish jerk to a truly evil character since the start of the series.
 * Sheila Broflovski: In Bigger, Longer, and Uncut, she shoots Terrance and Phillip in the head even after her son, Kyle, pointed out to her that starting a war against Canada and killing Terrence and Phillip was wrong and pointless.
 * Mr. Herbert Garrison: He tried to stop the gay marriage bill from being passed to the degree that he almost had Stan and Kyle killed, and also threatened to break Cartman's legs and burn his house down if he didn't take his forged egg.
 * Stephen &amp; Linda Stotch: Linda crosses it when she tries to kill Butters by releasing the brakes on her car which causes it to roll into the ocean. Stephen & Linda both cross it when they beat Butters so hard that it couldn't be shown on screen after Cartman frames Butters for trash-talking his parents. They then go downhill from there by selling him to Paris Hilton to locking him up in a basement and trying to feed him a woman they killed. Not only that, the attempt to 'ground' him for everything and anything, and Butters is so scared of his father he imagines him as a monster.
 * Grandma Stotch: She beat up and constantly bullied Butters to the point of him having a nervous breakdown for no reason.
 * The town of South Park: Constant pestering Britney Spears until she tries to commit suicide, and when it fails they continually do it while mocking her appearance. Ultimately, THEY kill her instead of her killing herself, so they could get a 'fresh harvest' of corn in the fall.

Spongebob SquarePants

 * Plankton: While in series he was a comedy villain, in the first movie he shows a much darker and psychotic side when he steals King Neptune's crown, frames Mr. Krabs for it, enslaves Bikini Bottom, shows excitement and joy when Mr. Krabs is going to be killed, and sends a bounty hunter named Dennis to kill SpongeBob and Patrick. In process, he has became a dangerous threat (as he also brainwashed King Neptune along with all the Bottomites via mind-controlling helmet at climax) against both entire ocean and universe had SpongeBob not stop him. Even in the series, however, Plankton still crosses the MEH (though the threat from his deeds are not on deadly level yet) throughout the special episodes like destroying Spongebob's favorite area "Jellyfish Fields", pops the gigantic purple goo to goo up Bikini Bottom after he got the formula from Krabs. He attempted to fry Spongebob and gang including Karen.
 * Burger-Beard: Burger-Beard crosses this by stealing Krabby Patty recipe through a magic book's powers, inevitably turned entire Bikini Bottom into post apocalypse state as majority of Bikini Bottomites unable to cope without Krabby Patties. He also stripped Sandy's intelligence from her.
 * Mr. Krabs: The episode One Coarse Meal has been debated as perhaps the darkest episode in the SpongeBob SquarePants series due to Krabs' actions. Upon discovering Plankton's phobia of whales, he dresses up as Pearl and terrorizes Plankton for 17 days, giving him nightmares and eventually leading him to attempt suicide. Spongebob offers to help Plankton by revealing Mr. Krabs's fear of mimes, one whom Plankton hires to terrorize Mr. Krabs in turn. Other than that, Mr. Krabs gets no proper comeuppance for attempting to drive Plankton to suicide (i.e. arrested), as he only had Plankton's hired mime scare him.
 * He also crosses it a step ahead earlier in Jellyfish Hunter, where he kills jellyfish in a factory just to get the jelly from them for the customers (after his defeat, he reluctantly took jelly off the menu). He also crosses it when he made lies in the newspaper, the Krabby Kronicle, which ruined the Bottomites lives (and becaue Plankton lost his restaurant thanks to Krabs, he mentioned "And I though I was evil") and even counterfeited money in the end (possibly unlikely to spend any of it), which is extremely illegal.
 * Finally, in The Cent of Money, he crosses it when he uses Gary as a coin magnet to steal coins from everyone and not caring for the snail's suffering (he even calls Gary a "sneagle" rather than a snail). This also confirmed that his money-grubbing behavior has drove him irreversibly insane.
 * Mrs. Puff: After years of putting up with SpongeBob's wreckless driving, she was finally driven insane in Demolition Doofus, when she apparently lost her ability to puff, thanks to SpongeBob. She later gets SpongeBob into a Demolition Derby in hopes of him getting killed by offering him "extra credit". As his bad driving makes him a star, Mrs. Puff snaps and tries to run over SpongeBob by using a huge monster truck. Instead, she destroys her boating school, but she turned back to normal and regained her sanity, only with disappointment.
 * Patrick Star: Has two potential MEHs:
 * In Pet Sitter Pat, he frequently abuses Gary by starving him, threatening him with a flamethrower (which fans consider the worst thing Patrick has ever done) in an attempt to get Gary to take a bath, bathes Gary with a hose and soap flakes, making Gary hit the wall in SpongeBob's pantry, and dries Gary with a hairdryer, because Patrick couldn't find any salt (which probably would have killed Gary). Unbeknowist to Patrick himself, this action has turning him into something that everyone (including himself possibly) greatly despised, as his low IQ has clouded whatever his good intention to taking care of Gary completely that ultimately drove him to do something that could killed Gary instead and became a figure that he despised.
 * In The Card, Patrick claims SpongeBob can't always expect his usual brand of stupidity, rather he likes to "mix it up, keep you on your toes", reveals that all this time, he aware with his stupidity, but have no concern about misery and damage that he potentially inflict on everyone due to the said stupidity.

 * Darth Maul: In the TV series, he manipulated Death Watch and Black Sun and turned them into his private army to conquer planet Mandalore, he put his puppet ruler in charge and killed Duchess Satine, Obi-wan's old love much to his sorrow while he smiled gleefully.

 * Grand Moff Tarkin: As one of the most infamous crossings of all time, he destroyed the planet Alderaan after making a false promise to Princess Leia that he would spare Alderaan if she revealed the location of the rebel base. Hoping to spare both, she lied and claimed the rebels were on Dantooine. Tarkin however decided to destroy Aderaan anyway, to frighten planets away from rebelling. He also planned to continue Emperor Palpatine's Empire after he was gone.
 * Jabba the Hutt: Jabba crosses the Moral Event Horizon when he orders Luke, Han, and Chewbacca to be thrown into the Great Pit of Carkoon to be eaten by the Sarlacc, after Luke slaughtered his pet Rancor, despite the fact that, in this situation, Han and Chewbacca were relatively innocent, whereas Luke provoked Jabba (though unintentionally; he was defending himself against the Rancor and didn't wish to kill it, but saw no other choice.)
 * Darth Vader: As Anakin Skywalker he cut off Mace Windu's right hand, helping Palpatine to kill him. He then became Palpatine's Sith pupil, for his order he masacred children in jedi temple, choked his beloved Padme after wrongly thinking that she betrayed him. For 20 years he preserved totalitarianism of the Galactic Empire, took over Cloud City, froze Han Solo and gave him to Boba Fett, cut off Luke Skywalker's right hand, and he, along with the Emperor, played on Luke's emotions after capturing him.
 * By Return of the Jedi Vader is shown to be subverting the crossing, as only Luke Skywalker believes that Vader still has a chance at redemption. Indeed, he proves his worth by saving his son (Luke) from the Emperor's shocks. Vader tosses the Emperor down the Death Star, killing him, but the shock power killed Vader as well.
 * Pong Krell: Krell crossed the MEH many times over, being stern and strict about Rex and the clones obeying his reckless orders that purposely led many of the clones in battle to their deaths with his strategies, ordered clone troopers Fives and Jesse to be executed for their defiance, he then tricks his men into killing each other and always sadistically gleeful whenever he killed a clone trooper when they turned on him after his treachery was revealed and taunted Captain Rex into shooting him, knowing that he could not bring himself to do it.
 * General Kalani: Killed millions of innocent people who were against oppression separatists in Onderon causing a massacre of civilians in mass of women, men, elderly and even children,and even after such atrocities against an entire planet, Kalani still alive waging war against the Galactic Republic at the outer edge, invading neutral planets or enslaving planets or races and allied Galactic Republic.
 * Savage Opress: He killed his brother, who helped him becoming Asajj Ventress' pupil as his final test. He commited numeroues genocides for order of Count Dooku, he killed king of Toydaria despite Count Dooku had earlier commanded him to capture him alive. He used intimidations and death treaths to find Darth Maul and save him. He helped him in building an army from gangsters to conquer planet Mandalore, which ended with a success.
 * Durge: He caused numerous mass murders under no orders, for no reason other than it's fun.

Megatron then cowardly and brutally murders Optimus when his back is turned. He also corrupted Sentinel Prime, though at climax revealed that this deed ultimately backfires as Sentinel turned out manipulate him all along so he can usurp his leadership over Decepticons, as revealed by Carly who convince him to attack Sentinel out of rage later. He also destroyed the monument of Abraham Lincoln to take the throne. These practically gives a logical reason why Optimus Prime lost his sympathize towards him as his "brother", as he avenge this MEH crossing deed either damage his face with his own cannon at Revenge of the Fallen or de-spine him in Dark of the Moon.
 * As Galvatron, he controls all of the KSI man-made transformers after manipulates KSI via knowledge of transformers physiology in his mind, making them a new Deception army, and attacks Hong Kong in order to takes back the "seed" and destroys the whole city.
 * Starscream - During battle where he involved in the movie, he crippled Ironhide and Ratchet as well as killed many human soliders. He also attempted to blow starship of the Autobots to kill them under Dylan's order.
 * The Fallen: He betrayed his brothers Primes out of pure spite toward humans by tried to gather Energon from Earth's sun which could anihilating the planet in the past, and then started a war on Cybertron. He tries to resume his plans once more after had Megatron assassinate Optimus, but ultimately killed by a revived Optimus himself.
 * Sentinel Prime - He betrayed the Autobots to the Deceptions, executed Ironhide (and the Twins Mudflap & Skids in an unused draft seen in the comic adaptations) and tried to ruin Earth and enslave human race. Worse, it turned out that he manipulate Megatron all along as he proceed to usurped the Decepticon leadership so he can have Decepticon army all by himself only to made his plans goes smoothly. On top of that, damage that he caused was too great; human government lost their faith with the Autobot, and Harold Attinger use it as propaganda against Cybertronians on earth further.
 * Dylan Gould - Betrayed humankind to the Decepticons and worked as their spy as well as ordered his bodyguards to beat Sam and had Starcream shoot the Autobot's ship. He also personally blackmailed him, mocked him and attempted to kill him. Other reason to hate him was when Dylan reveal his true color, he has already became one of high-ranking Decepticon command and receiving disappointing death (merely electrocuted by one of Sentinel's pillar).

In an unused draft which is still seen in the comic adaptations & junior novelizations, he killed Dino/Mirage instead & uses his corpse to taunt the Autobots. His crossing of MEH are all avenged when Bumblebee kills him.
 * Lockdown (Transformers Film Series) Starts by ripping the spark out of the gravely injured Ratchet, killing him. Later Lockdown destroys the Yeager family home during the Cemetery Wind chase scene in Texas and kills Cade's friend Lucas by throwing a grenade and turning the man into a statue of transformium. He also tries to recapture Optimus by using a giant magnet from his ship by absorbing metallic objects then dropping them on the Autobots in Hong Kong endangering many civilians in the process.
 * Harold Attinger - Crosses this by using events in Chicago in Dark of the Moon as propaganda against Cybertronians on earth further. Thanks to this, no one able to against him when he had many Autobots hunted down and killed (as well as purge other humans that proven gets in his way or not) until his nefarious actions ultimately put into an end at hands of Cade Yeager & his family with help of Autobots, and presumably restores mankind's faith towards Autobots in process. Other reason to hate him are he had manipulated both Brains and his pawn Joshua Joyce to creates mass produced artificial Transformers using the corpses of the Decepticons as well as some of the Autobots he had killed as ruse to gain a Seed for himself as he had secretly had a deal with Lockdown to do so. His deed when he created mass produced Transformers ultimately backfires when he uses Megatron's remains to create Galvatron, whom not only revive Megatron inside it, but also evolved into stronger Transformer whom proceed to took other artificial Transformers to his side. Fortunately, most of his actions are avenged when Optimus shoots him in the chest.
 * Joshua Joyce's betrayal as soon as he aware with Attinger's dark nature also revealed that Attinger's whole records of evil actions (includes his MEH crossing deeds) would threatened to ruined both KSI and Joyce's good name and turned them all into war-criminal like Attinger and Savoy himself. All of these are something that Joyce greatly despised, as in fact, Joyce actually wants to made the world into the better place, not induce the chaos toward it instead like what Attinger actually done in spite of Attinger's intentions.
 * James Savoy: Has already a step ahead by threatens Tessa in order to force Optimus Prime out of hiding. Later he tries to brutally kill Cade Yeager and his family in Hong Kong.

Shortly afterward, she plummets and apparently drowns.
 * Judge Claude Frollo: Killed Quasimodo's mother and tried to drown him simply because he was deformed. Later in the film, he let him get hit with fruits by the guards and citizens (simply because he had decided to attend a gypsy festival), and sniffed Esmeralda's hair (despite hating gypsies). But worst of all, in order to track down Esmeralda, Frollo tries to kill an innocent family (children included) by setting their home on fire just to set an example (as well as a few other buildings in Paris). Later, after finally arresting the gypsies at the Court of Miracles, he sentences them all to be burned alive at the stake for witchcraft. Last, but not least, he savagely tries to kill Quasimodo (who was his adopted son) and Esmeralda atop Notre Dame only to be condemned for his actions and fall to his death in a pool of molten lead.

This has been a particularly notable example that was acknowledged by numerous audiences when first seeing the film theatrically, particularly because Lotso did have a tragic backstory, but denied the perfect opportunity to redeem himself.
 * Professor Ratigan: Tries to assassinate Queen Moustoria by feeding her to his cat, Felicia. It is also stated (and often debated) that in his song, he drowned widows and orphans.
 * Prince John: Ordered Friar Tuck to be hanged, knowing that in doing so he would lure out Robin Hood. Sir Hiss was shocked that he would do such a thing.

 * Giant Magnet: Although originally designed to destroy, he constantly tried to send the appliances on the converor belt, which leads to the crusher. And later, he placed their "master" on to the belt.
 * Chick Hicks: Deliberately sideswiped King just to win the Piston Cup. The crowd turned on him and booed him for this.

 * Miles Axlerod: Though his identity has not yet been revealed at this time, he orders that McQueen be killed for saying that he'll continue to use Allinol in the next race.

If not, they cross it when they rig Mater with a bomb and intend to blow him and McQueen up when he gets too close.
 * King Stefan (Maleficent Film): Despite the fact that he was remorseful for stealing Maleficent's wings and he once befriended her (as well as introducing her to true love's kiss), Stefan eventually hated Maleficent once she retaliated by cursing Aurora, so much to the point that he was driven to the dark side farther than Maleficent herself was. He left his dying queen to perish for the sake of his obsession for hunting Maleficent, sent his men to hunt the fairy down (only to return with failure and severe injuries), and then tried to stab her from behind when Maleficent spared him. Another reason to hate him was he HIMSELF was responsible for pinning her to the dark side in the first place by stealing her wings.

He drinks the potion in front of his brothers and instead of healing the family bonds he has broken, accepts the form of the giant bear he has been turned into and slaughters them and his kingdom's civilians in cold blood. In the movie, he attacks the highland clans and makes attempts to kill Merida until Queen Elinor comes to the heroine's rescue. As it's implied, Mor'du symbolizes what Merida would turn into if she became too obsessed with her anger towards her family and her kingdom.
 * Maxim Horvath: Had betraying Merlin by allowing Morgana killed his former mentor soon after broken-hearted by the fact that Veronica chooses Balthazar as her love interest instead of him not enough, killed his own minions would be it.

However before the film, it is stated that he had committed many genocides and killed Drax the Destroyer's wife and daughter, and during his battle with him, told him that he doesn't care to remember and he'll forget killing him as well, but when he does recall, later, he only regarded that their screams were pitiful. When the Infinity Stone is removed from his warhammer and Quill grabs at the cost of his life, Ronan only shows a sadistic smile. All of this makes him one of the most monstrous, psychotic and despicable villains in the Marvel Cinematic Universe.

 * Aldrich Killian: He crossed it after destroying Tony Stark's home, killing Maya Hanson and then capturing Pepper Potts (while subjecting her to the Extremis in the process) and the President, nearly killing them both. Kilian's action in subjecting Pepper Potts proved to be his own undoing, as Extremis-enhanced Pepper suddenly came to Tony's aid before he could deliver a final blow on already crippled Iron-Man.
 * Alexander Pierce: He crossed it when he killed his maid/housekeeper when she caught him having a conversation with the Winter Soldier about HYDRA operations in his home. Worse, result of his Project Insight, albeit foiled by Captain America, proved disastrous due to making S.H.I.E.L.D organization nearly destroyed.

The character Haydee Tebelin was purposefully sent to the opera house so that she could be forced to see Fernand Mondego, the killer of her father and the one responsible for her and her dead mother's enslavement, making her have post-traumatic stress that would eventually build up until she confronted Mondego during his campaign. After the Count explained his use of Haydee and Albert, his entire scheme had essentially become one big Moral Event Horizon. Also, in the episode called "The Duel", Franz d'Epinay takes Albert de Morcerf's place in the duel against the Count and loses, dying by the Count's sword. Afterward, the Count plays chess, seemingly treating his cruel actions as if they were nothing, and when Haydee confronts the Count, Bertuccio is ordered to take her away.

If it hadn't been for Kitty and Dudley, Snaptrap would have killed hundreds of innocent civilians.

He even broke his promise of not telling the kids by doing it anyway, leaving Eddy humiliated and mocked at.
 * Sarah: (This is debatable due to redeeming herself in the movie) In the episode, Run For Your Ed, she betrayed the Eds to the Kankers (with an evil grin) because they possess the ship in a bottle, thinking they would suffer the same fate as she and the other kids in the Cul-De-Sac.

 * Joker: Was already far over the line and cements it by inflicting the Bad Ending on the Cures. And that's not going into how, in brainwashing them and Akaoni, he was behind Wolfrun's vendetta against Akane and everything she cared about, including the destruction of her charm and the subsequent attempt on Miyuki's life, and Majorina's attempted murder of two of Nao's siblings.

Garma, eager to prove himself, takes the bait and as soon as his Gaw attack carrier flies over the stadium, the White Base launches a surprise attack on Garma's Gaw. Desperate, Garma attempts a kamikaze run on the White Base, while Char contacts him informing of his treachery, saying to Garma that he should blame this on the misfortune of his birth and he should thank his father, ending it with a maniacal laugh, as Garma's Gaw explodes before it could collide with the White Base. Others think that he crossed it when he decapitated Kycilia Zabi with a bazooka. However, Char (despite his delusional goals and beliefs to migrate all of mankind on Earth into space, so that all of humanity will evolve into "Newtypes", and allow the Earth to heal itself) actually crossed the line in "Mobile Suit Gundam: Char's Counterattack", when he dropped the asteroid "5th Luna", onto Lhasa, Tibet, killing billions of innocent people and attempted to complete his plan by dropping the asteroid "Axis", filled with nuclear missiles onto Earth, in order to ensure an endless nuclear winter that will render the planet uninhabitable. And he deceived and manipulated his underlings feelings with his charisma for his own ego.

She then does it again by stealing Asia's Twilight Healing, killing her in process & then told Issei that it is the deserving fate of all Sacred Gear users to have their Sacred Gear stolen by Fallen Angels in process.
 * Megatron (Transformers Prime): He crossed it in the season 2 finale of Transformers: Prime when the Autobots seized the Omega Keys and secured the Omega Lock (the sole device in the universe that could restore the war-ravaged planet Cybertron). In order to retake the Omega Keys and the Lock for himself, per Starscream's advice, Megatron had the Autobots' human friends taken to Cybertron in air-tight pods as hostages, threatening to open them and expose the humans to Cybertron's toxic atmosphere (and possible lack of oxygen), which would kill them instantly, unless the Autobots relinquish the Omega Keys to him. Though the Autobots did exactly this, even after Optimus Prime asked that he be allowed to return the humans to Earth, Megatron instead elected to use the Omega Lock to cyberform Earth, which would destroy all indigenous life in the process. Optimus made the ultimate sacrifice by destroying the Omega Lock to save Earth. In the aftermath, Megatron, having discovered it's location, destroyed the Autobots' base on Earth. Megatron also crosses MEH again by destroying whole Predacon Project and framing Autobots for this to avoid any possibilities of the cloned Predacons' betrayal due to Predaking's sudden developed intelligence as well as to manipulate Predaking further to inflict his rage on Autobots until Ratchet told Predaking the truth, which prompt Megatron to left Predaking to die in the outer space. Fortunately for the Autobots, this second MEH crossing costs Megatron more, as most of his Vehicon soldiers died at hands of Predaking before he able to rid of him, as well as his downfall at hands of revived Bumblebee later.

Once Jack and Arcee arrived to rescue Jack's mother, Airachnid immobilized Arcee with her webbing. Arcee then pleaded to Silas to help Jack and his mother, since they are humans like him, but Silas outright stated that "a few humans lives are a small price to pay for a miracle of science like [herself]", and simply watched as Airachnid attempted to kill both humans. This also proved Silas to be even less human than the Decepticons. He crosses it again in the following season when he frames Optimus Prime by constructing a remote-controlled doppleganger of him, Nemesis Prime, which he first uses to try and kill the Autobots' human liason, Agent Fowler, and then turn the military against the Autobots by attacking a military base. Despite military orders to terminate all Autobots on sight, Optimus and Fowler locate Silas' base and destroy the doppelganger, ultimately clearing Optimus' name. As retribution for his actions, Silas is inadvertently crushed beneath the destroyed doppleganger he created. His troops worked diligently to save his life by integrating him into the body of the deceased Decepticon, Breakdown, the remains of whom they found prior. Though their efforts brought Silas back from the brink of death, he crossed the MEH to the point of no return by killing his own men with the intention of joining the Decepticons.
 * Airachnid: Crosses this by brutally murdering Arcee's close friend Tailgate. He also tries to kill Jack as well as make a deal with Silas in which she turned out planned to had Darby watch his mother die.

Gumball also, when Alan feigned Gumball finally finding his weakness and breaking him, chose to gloat and relish in his own alleged victory. Darwin was completely disgusted at Gumball choosing to do this, and Gumball nonchalantly revealed that he simply wanted to break Alan "for science, and because the people deserve to know, and because I've got nothing else to do today." Even Gumball himself worried after selling Alan's parents that he was going too far, and Darwin said, "You went too far about seven hours ago."
 * All the main villains in Winx Club are pure evil, but the Wizards of the Black Circle particularly proved irredeemable; Even with the critical situation they were in, with the earth fairies seeking vengeance on them and Duman seriously ill, they were faking their surrender in an elaborate plan to destroy all fairies, which they never once considered backing out of even with the Winx going out of their way to help them.

We find out just how completely depraved and insane Branka is when it is revealed that in order to reach the Anvil of the Void, she sacrificed her house — three hundred plus dwarves — to the Darkspawn and allowed the women to be taken to become part of the Broodmother (a process that defines horror) just so she could have Darkspawn to throw at the traps surrounding the Anvil. The sole survivor, Hespith, explains it in simple terms:
 * The stories of Flemeth indicate she became irredeemable when she started to take over bodies of her daughters to extend her existence
 * Marjolaine crosses it in the DLC Leliana's Song where the player gets to see Marjolaine's betrayal of her friend/lover firsthand.

 * Quentin not only killed a lot of women, but also disrespected their corpses by chopping them and turning them into a twisted attempt to recreate his dead wife.
 * Anders crosses the line when he blows up the Kirkwall Chantry, killing the Grand Cleric and presumably all of its priests in order to destroy any chance of compromise between the Circle and the Templars as the Grand Cleric was the only one who could calm both sides down. He willingly started a war, even Orsino scolded him for this, because he may have doomed their whole kind, or at least the mages who live in Kirkwall.
 * Then Knight Commander Meredith followed him when she used it as an excuse to annul (exterminate) a Circle of Magi that Anders never even belonged to and were not involved in his crimes. However if player takes her side, she can be persuaded to spare mages, who beg for mercy, including player's sister Bethany.
 * Then Orsino crosses it when he reveals that he knew about and protected the Serial Killer blood mage Quentin. While he downplays his crime in the Mage path, he is wholly unrepentant in the Templar path about being complicit in the deaths of several innocent women, including Hawke's mother Leandra. He even uses the fruits of Quentin's research to turn himself into a literal monster after the reveal.
 * Mother Petrice crosses it when she murders Seamus Dumas, tries to frame Hawke for it, and plans on using the entire affair to incite the citizens of Kirkwall to rise up and wage war against the Qunari. Her apathy towards Hawke pointing out how it will be a massacre on both sides of the conflict further solidifies just how much of a deranged zealot she really is.

It was then that she decided to create Protos Heis/Sophie in order to help rid Fodra (later Ephinea) of Lambda.

 * Maximillian Lionfang: He crosses the MEH about four times; in the Thunderforge saga, he begins torturing the staff of Artix Entertainment in an attempt to get them to accept his way of doing things, and later wastes the last vial of the Tears of the Mother on Drakath, and when he finds out that it didn't effect him, he goes so far as to try to murder the hero due to being sick of what he believes to be his/her tricks and lies. In the 2010 Frostval event, he burns the Frostval gifts in front of Blizzy to his horror and laughs about it, which sends the hero into a ballistic rage with the promise of making him pay for it. Not long after his defeat following that, he, in one more act of spite against the alliance between good and evil, knocks the snow globe containing the Frostval Spirit out of the hero's hands and shatters it, and lays bare his intent to make the whole world pay for "pledging allegiance to evil" by destroying Frostval, but the Frostval Spirit cannot be destroyed, as she returns to his shock and disbelief in order to set things right again.
 * Drakath: While the siege of Swordhaven by Drakath's forces is pretty standard villain fare by this point, and chaorrupting Swordhaven's sewers is a new level of low, everything takes a turn for the worse when King Alteon finally succumbs to the Chaorruption he's been having to deal with all game thanks to Drakath's first appearance, becoming the Twelfth Lord of Chaos and striking down his eldest daughter and heiress to the throne, Princess Brittany, in a fit of Chaos-induced madness — and right when she had just gotten married to Lord Brentan! And to make things even worse, this tragic act happens to be the trigger for unleashing the worst Chaos Beast yet: a massive, three-headed Chaos Dragon who unleashes horrific devastation upon Swordhaven before the hero is able to take it down, and King Alteon himself ultimately has to be slain when the Chaos proves too much for him. Because of all of this, Swordhaven will never be the same again, and will most likely never know peace for a long time due to the inevitable conflict for the throne. And from Drakath's smile as the twelfth seal is broken, players can just tell that he's enjoying the whole show. Later, after besting the hero in battle, he chaorrupts him/her into the 13th Lord of Chaos and gleefully watches his final, world-ending Chaos Lord wreak havoc in Willow Creek, Doomwood, Darkovia, Vasalkar Lair and Battleon and summon his/her Chaos Beast, the Eternal Dragon of Time. After being attacked by the hero and revealing him/her to be the Dragon of Time, he then murders him/her and then crushes his/her soul within his hand and controls Death into preventing him/her from respawning like normal, which allows him to free the Queen of All Monsters.

Either way, Trish dies, and Cole swears revenge on Kessler over his former girlfriend's grave.

 * This was not sole reason to hate her, however. In fact, the consequence of Augustine's plans would be a war between conduit and humans, something which dreamed by Joseph Bertrand III in the past. Worse, her evil actions proved be more active and more aggressive manner than Bertrand ever did; Hunt every single conduit gene possessors and lock them as well as infect whole Akomish Tribe's body with concrete that slowly kills them. Nevertheless, all of her actions are what was drove Delsin to kill/stop her at all costs from start(incarcerated her in Good Karma/destroyed in Evil Karma).

 * Christy Jenkins: After the Charmed ones and her sister, Billie Jenkins, killed her demon master, Dumain, she attempts to kill her sister by hurling a fireball at her, but her sister deflects it back to her, kiilling her sister, an act that not only made Christy cross the MEH, but also redeemed Billie, albeit, Billie's redemption came at a terrible price; The Loss of her sister, the last remaining close relative she had after her parents were killed by the Triad.
 * Gideon: After he killed his friend, Sigmund, when he decided to tell the Charmed Ones of his betrayal and his plot to kill Piper's infant son.
 * Kira Nerys: After she killed Jennifer Sisko when protected Jake Sisko, her prime universe's counterpart's son, when she was escaping a Terran Rebellion-controlled Terok Nor.

 * Trinity Killer: Crosses it when he kills Dexter's wife.
 * Daleks: Have committed countless war crimes and acts of pure evil and genocide across the universe over their species' history.
 * The Daleks arguably fully cross the MEH onscreen in "Evolution of the Daleks", when the rest of the Cult of Skaro betray Dalek Sec and resume the Daleks' evil and genocidal ways, rather than follow Sec in sacrificing their purity and emotionlessness for the sake of their future. This can be considered the Daleks' truest MEH-crossing, because they'd had an actual chance to be saved from the darkness and redeemed by sacrificing their evil old ways, but had instead refused to let go of their omnicidal xenophobia and concept of Dalek purity, thus forsaking the Daleks' only chance at a better existence.
 * Destiny (Mongrels): Though Destiny has committed many selfish, greedy, immoral, petty and cruel acts without any respect or regard for anyone other than herself over the course of the show, she crosses the Moral Event Horizon when she attempts to murder Gary, her own owner, with poison, all just so Marion wouldn't be favoured by Gary when Marion temporarily became a second pet.
 * Dana Walsh/Jenny Scott: On 24. When lying and hiding her identity and old life from CTU and Cole (as well as assisting reluctantly in crimes that her ex-boyfriend and his partner commit), she still manages to maintain sympathy. Even when she kills Bill Prady and covers up his death, it's seen as an act of desperation by someone who'd felt they'd lost all other options. It's not until she calls Samir Mehran and she's revealed to have been a mole working for the terrorist the whole entire time that she is then established as a full blown enemy no longer worth rooting for. Somewhat subverted by her later torture and alliance with Jack and Cole, her still apparent feelings for Cole and her somewhat uncalled for execution at Jack's hands.
 * Patrick Kemp: Crosses the Moral Event Horizon either when he begins murdering werewolves using the decompression chamber, or when he murders Hennessey and exorcises Annie.
 * Dian Lamitan: She physically abuses Dal'lang, tries to kill Amaya when she was a kid, lied to Rajah Mangubat that Datu Bugna is a traitor as a revenge for slapping her for attacking Amaya & so she could easily stripped Amaya out of her position as a princess & turn her into a slave as well as abusing her, forced her favorite daughter Marikit to divorced Bagani & marry his father instead by using a love potion on him then aborts her offspring with Bagani that made her insane & then drugged her so the rajah won't find out about this, conspired with Uray Hilway & Angaway after Rajah Mangubat betrayed her upon finding out her schemes & upon regaining her position as a Dian, she told lies about Amaya about her being an evil person & declared her as an outcast, blackmails her less favorite daughter Binayaan by harming Dal'lang who had become her adoptive mother, she conspired against Angaway on her own as well (upon finding out Amaya & Bagani are planning to attack him) by bribing Datu Pulajan into joining her side & then invited them into a ball by serving poison on both sides excluding hers', had her rival Hara Lingayan killed secretly, bribed many soldiers & officials to do her bidding, took Dayaw as a hostage so that Posaka will surrender Amaya to her but was secretly planning to kill both of them but Dayaw escapes upon finding out and commits suicide, which Lamitan quickly finishes him off, had Asinas killed for conspiring against her, betrayed Datu Pulajan after discovering he made a secret alliance with Amaya by poisoning him & taking control of his army & tried to massacre civilians in an attempt to force Amaya & Bagani's forces to surrender, only to fail. She even took Alunsina, who was a little girl, hostage & warns everyone she will kill her if they tried to stop her so she could escape her death penalty and escape to a faraway land. Most of her actions are avenged when Rajah Mangubat stripped her off her position as a Dian, when Amaya chopped her hand off & voodoo her to lose her agimat's power & when Amaya finally kills her by summoning Bakunawa to devour her.
 * Xena: in an alternate reality where Xena was never reformed, had Gabrielle, who was the one person Xena love the most in the Prime Xenaverse reality, crucified for standing upto Xena's reign of terror.
 * Veronica Harrington in The Haves and the Have Nots crosses the Moral Event Horizon a few times:
 * After her son Jeffrey comes out of the closet, she gives him a hateful speech about how his homosexuality is a punishment from God for her having an abortion in college, and essentially wishes her son was dead.
 * Firing Jeffrey from his job as a counselor at her rehab clinic, and depriving him of his finances and apartment.
 * Blackmailing Jeffrey into dating women by threatening to have him arrested for the murder of a young girl (Wyatt Cryer, while high on drugs, drove Jeffrey's Sedan and hit and killed the girl, and also left Benny Young in a coma).
 * Threatening to have Quincy Maxwell's family murdered if he doesn't back down.
 * Ordering Quincy, a convicted murderer, to beat up Jeffrey if he doesn't reveal Candace's whereabouts.

Supernatural

 * Lucifer: Murders the women and children of a small town and sacrifices several of his loyal demons (who are possessing the town's men) as part of a ritual to free Death; about the demons after they're killed, he nonchalantly remarks that they're "just demons," showing he doesn't care about them despite the fact that they adore him and worship him as their god. Lucifer also, before the series, was responsible both for corrupting the original humans and for fathering the demon race by torturing and corrupting Lilith into the first demon (a deed which as revealed in Season 10, done immediately after infected by The Darkness' malice).
 * Gordon Walker: Arguably crossed the Moral Event Horizon at one of several points through the Supernatural series:
 * Before the events of the series, he hunted down and killed his own sister after discovering she'd been turned into a vampire.
 * Viciously tortured and attempted to wipe out and murder Lenore and her nest despite being aware that they were only killing cattle and were genuinely trying to avoid harming humans. In anime adaptation, he did it on a family of good vampires instead.
 * Started feeding on and turning humans after becoming a vampire, and attempted to kill Sam despite the latter's special child powers having become inactive since Azazel's death.

Sleepy Hollow

 * Moloch: He is a corruptive, emotionless and cruel demon king who enjoys punishment and torture towards his failed minion. He makes many acts that cross the MEH and making him so far the worst antagonist of the whole series:
 * Season 1:
 * Pilot – He famously crosses it when snapping Andy Brooks’ neck for his failure and then changes the video footage and makes it to show Andy committed suicide, confusing Captain Frank Irving.
 * Blood Moon – Moloch revives Andy to make him his soulless undead servant, and then Moloch forces Andy to release the burning soul Serilda of Abaddon, one of his witch servants and the leader of the Order of Blood Moon. Serilda’s quest for reconstructing her body causes a man (who is a descendent of an anti-witchcraft judge) burned alive in his car.
 * Necromancer – In the past, Moloch let his Hessian minions shot Abraham van Brunt, the former best friend of Ichabod and the ex-fiancé of Katrina. Then, Moloch transformed Abraham into the Horseman of Death after promising him to give him Katrina as his price, which was one of the main reasons of Katrina’s imprisonment in Purgatory. However, Moloch never takes the promise seriously. In the Modern era, after Crane, Abbie and Irving captured and imprisoned the Headless Horseman, Moloch forced Andy Brooks to hide the Thracian Phiale, which the Hessians burgled from Jesse Adams, inside Brooks’ body. While the Headless Horseman and Brooks was both in captive, Moloch ordered at least seven Hessian troops to blow up the Sleepy Hollow West Power Grid, causing a massive blackout and shut down the UV lights that weakened the Death in process. With the lights shut down, the Headless Horseman regained his power. After that, Moloch forced Brooks to take out the Phiale and then broke the hex of the cell. This unleashed several demon troops, as well as making the Horseman broke free and escaped unharmed.
 * Sanctuary – In the past, Moloch sent the Tree Monster to the Fredericks Manor, the sanctuary where a pregnant Katrina hid as she gave the birth of her son. Katrina fled safely with her friends’ help. However, due to the protection hex of the manor had broken since Jeremy Crane’s birth, the Fredericks Manor now is no longer a safe place but just a haunted house and a center of dark arts controlled by first tree monster and then Jeremy Crane.
 * The Golem – At the Christmas Eve, Moloch summons Ichabod Crane to Purgatory, and then he prophesizes the Horseman of War’s arrival before threatening Crane to bring Abbie Mills’ soul to him. This reveals the reason that Moloch forbids the Horseman of Death to kill Crane.
 * The Indispensible Man – Moloch turns Andy into a mindless demon. He also plans to let Ichabod finds the map that Washington protected, in order to make himself descend on earth.
 * Bad Blood – In the past, he summoned Jeremy Crane buried beneath the ground and made him the Horseman of War. In order to prevent something went wrong, he brushed off Mills sisters' memories and locked it in the Purgatory. In the present, he manipulate the two Witnesses' seperate by trapping one of them in the Purgatory as the price of saving Katrina, which later Abbie was forced to do that.
 * Season 2:
 * This is War - Moloch summoned the demonic souls from the Purgatory and was ready for his ride as soon as the Hessians used the Ghenna Key to open the gate of the Purgatory.
 * Root of All Evil - Lori Roberts’ last diaries implied that the demons lead by Moloch were tormenting her and hunting her daughters. Abbie said her mother fell into Moloch’s hand and so she committed suicide tragically.
 * Go where I Send Thee… - Moloch summoned the Pied Piper from death, and so he was responsible for the Piper’s heinous curse against the Lancaster family.
 * Weeping Lady - Moloch furiously scolds and punches Henry for making Katrina’s life in risk, for she is one of the Hellfire Shards, a chosen vessel. Henry explains that the Weeping Lady did not meant to harm Katrina and this plan is just for pleasing Moloch, yet Moloch coldly says Henry had no rights to plan or think for himself. He then states that Henry is just a soldier with only one duty - obey.
 * Heartless – With Henry’s help, Moloch’s energy has transported into a glass bottle. He eats the human soul as energy that the Succubus collected for him to take his baby form. In order to feed Moloch, the Succubus had to attack at least four people (including Ichabod and Hawley) in one night, killing at least two.
 * Mama – More than a decade ago, Moloch sent the ghost of Gina Lambert and let her to capture Mills sisters. The sisters’ mother, Lori Mills, were trying to protect and save her children from the demon. In the present day, in his baby form, Moloch takes some of Katrina’s power by sending her the breath of demons when Katrina hugs him without noticing the baby is in fact Moloch. With Katrina’s power, the demon grows rapidly towards his fully form.
 * The Akeda - Moloch, who managed to take his fully form, burns down the first two white trees to bring lightings and blood hails down to the town. After burning down the third tree, he summons his demon troops to roam the earth. Later, Moloch orders Henry to capture the Witnesses and their allies as soon as possible, even knowing Henry had his Horseman armor destroyed and in a vulnerable state and will die under the Sword of Methuselah. Moloch even states that there were Horsemen before Henry and there will be new Horsemen after him. After Henry captures Ichabod, Abbie, Katrina and Jenny, Moloch orders Henry to destroy Katrina and burn down the fourth tree, even knowing he WILL break his promise to Abraham of bringing Katrina to him. He coldly reveals that both Henry and Abraham are meaningless to him. Moloch’s words make Henry to see the demon’s true nature, and soon Henry stabs Moloch to death with the Sword of Methuselah.
 * The Headless Horseman: He steals a white horse as his new ride and kills the horse’s former owner, yet his first action to cross MEH is which he brutally chops down Sheriff Corbin’s head right after that. After having himself and Crane’s blood tie destroyed by Henry, the Headless Horseman was free to slaughter and then he immediately beheaded four Freemasonry leaders of Sleepy Hollow.
 * Jeremy Crane: After he reveals his identity as both the Horseman of War and Jeremy Crane, Henry hands Katrina to the Headless Horseman and buries Ichabod in the coffin where he laid for two centuries. Later, he claims Frank Irving's soul.
 * Banastre Tarleton: He is a sadistic and twisted torturer who is fond of hanging and killing people (espeacially if the implication is there a traitor) without any mercy and regret. Furthermore, he secretly stalked Ichabod Crane and then brutally crossed the MEH when shot down Arthur Bernard, who Ichabod just spared, to die. Then, he angrily regards Ichabod as a traitor just before his transformation to his real demonic form, making all of his words against treachery became some sort of ironies.
 * Ancitif: While possessing Luke, Ancitif lets Devon brushing off all of the salts that Father Boland spread in front of the door and then kills Devon by snapping his neck. After taking control of Macey Irving, Ancitif beats Luke unconscious and leaves him to die. One vital thing is, both Luke and Devon were Ancitif’s former vessels, and yet Ancitif mercilessly attacked them both as soon as they were useless for him.
 * Pied Piper: The Piper dealed with the devil and slaughtered many people in brutal ways. For revenging Daniel Lancaster’s betrayal, the Piper kidnapped Lancaster children when they had their ten-year-old birthday by luring them into his lair using his magic flute. He froze or starved the children to death and used their bones to make his new flute. However, what makes the Piper a heinous CM is the Sadistic Choice he gave to Lancaster parents—if the kidnapped child survived or saved by someone else, other children in the family would fall ill and die in one day.
 * Mary Wells: After returned from death as the Weeping Lady, she drowned Caroline for the jealousy of her friendship with Ichabod. She later attacked Abbie and nearly killed her. Then, Mary attacked Katrina after learning she is still alive and well.

 * Lady Macbeth: She convinced her husband to kill king Duncan.
 * Macbeth: Crosses it when he committed a regicide of king Duncan to take his place.

Harry Potter

 * Lord Voldemort: It is said he was evil from the start, but at a young age, he tortured 2 children in a cave, and killed somebody's pet rabbit. Others would argue that he crossed it by creating his first Horcrux by killing Moaning Myrtle and framing Hagrid. He later killed his father and grandparents and framed Morphin (his maternal uncle) in order to make a second Horcrux. Some might say that he crossed it when he murdered Harry Potter's parents. J. K. Rowling has said, before the Deathly Hallows came out, that he was the only character who had no chance of redemption (despite Umbridge, Bellatrix, Greyback, Wormtail, and Crabbe (Goyle in the film) also crossing the Moral Event Horizon). In Half-Blood Prince, it's finally explained that the reason he turned to the dark side (or rather already there by the time of his birth) was due to his lack of love, something that his mother had not given to him before her death (even his conception was a result of a love potion, which can only imitate love). This practically made him live on a cursed life as a horrifying abomination/monster whose nature was the complete opposite of Harry's in some ways (for instance, Harry's mother-Lily-shielded Harry before her demise. Voldemort's mother-Merope-chose to die rather than raise him herself (although Merope may not have had a choice, as she died a mere hour after giving birth to Voldemort)).
 * Dolores Umbridge: Crosses it by sending Muggle Borns to Azkaban and threatening them with the Dementor's Kiss if they resist. It may have been before that, when she sicced Dementors on Harry, forced him to write lines with a Blood Quill, attack Hedwig for his mail, threatened to use Veritaserum on him, and threatened to use the Cruciatus Curse on him.
 * Peter Pettigrew: Crosses it by betraying James, Lily, and Harry Potter to Voldemort and subsequently killing 12 Muggles at once via blasting curse and framing Sirius Black for these crimes immediately after betraying the Order of Phoenix. He crosses this again by killing Cedric and helping Lord Voldemort return to power. He did those things out of fear rather than loyalty to Voldemort, but these acts still make him despicable to the point where he can't be redeemed even though he does show a small amount of mercy when he remembers the life debt he owes Harry Potter.
 * Bellatrix Lestrange: Crosses it by torturing Neville's parents into insanity and killing Sirius, and only moments before his innocence was proven. She arguably became a Complete Monster by brutally torturing Hermione and killing Dobby.
 * Fenrir Greyback: He was immediately established as a dark character when he is introduced in the series. He could have first crossed it when he bit Remus Lupin or more likely the first time he bit or killed a child. He definitely crossed it when he threatened to kill and eat Hermione Granger when she was being tortured by Bellatrix.
 * Vincent Crabbe: Tries to kill Hermione with Avada Kedavra in Deathly Hallows (which misses and inciting Ron's fury in process), and later tries to incinerate the trio with Fiendfyre, which ironically ends up killing only him and even helps the trio by destroying the Horcrux they were looking for at the time.
 * Barty Crouch Jr. : He crosses it by taking part of the torture of Neville's parents, although it was never officially confirmed that he was involved it was most likely that he was since he was associated with the Death Eaters at the time. He crosses it again by killing his father.
 * Gilderoy Lockhart: Tries to erase Harry and Ron's memories while they're in the Chamber of Secrets, which would have prevented them from rescuing Ginny and getting out of the Chamber alive.
 * Lucius Malfoy: Plants Tom Riddle's diary in Ginny's book bag, intending for it to work dark magic through her. In the movie, he crosses it again by attempting to use Avada Kedavra on Harry, which fortunately stopped by Dobby.
 * Vernon Dursley: In Order of the Phoenix he threatens to kick Harry out of the house knowing very well doing so will put Harry in mortal danger, but he reluctantly gives in when Petunia gets a letter from Dumbledore and she tells him that Harry will have to stay.

They committed terrorist attack and murders, and they even set up a evil plot to destroy Poirot once and for all. No. 4 (Claud Darrell) set an explosion, which knocked down Hastings and killed Poirot (yet Poirot was later revealed to be survived).
 * However, in the TV series, the whole insane plot was solely set by No.4, Claud Darrell (real name whose real name is Albert Whalley, and whose most prominent disguise in the adaptation is that of Paynter's physician, Dr Quentin), while the rest three "members" were all pacifists under Darrell's incrimination and brainwashing. Darrell is a a brilliant but insane character actor who orchestrates the entire Big Four setup, feeding the press with sensational clues and threatening letters and killing his victims to implicate the Peace Party members (whom he then kidnaps and drugs with immobilising gelsemine) thus validating the organisation's existence. His motive in doing all of this is to attract the admiration of Flossie Monro, who becomes an unrequited lover whom he showers with anonymous gifts and cards expressing his love for her. It transpires that Flossie told him he wasn't good enough for her in the past, and the mad scheme is an attempt to make himself the international celebrity he believes she desires.
