Even Evil Makes Mistakes is a scenario where a villain whom, during performing something wicked, made a terrible mistake that results disadvantages on their side or worse, defeat by the hero.
Over the course of conflict between good and evil where the hero finally defeated a villain, the said victory is not always contributed by the hero alone. When the wrongdoer worked on his/her evil schemes, he/she sometimes missed some flaws in the said schemes, resulting a loophole which either results in the said plan not going like what it was intended to be or the hero being given better advantage.
Aside flaws on evil plans, other forms of mistakes that a villain done that causes severe disadvantages in the conflict between good and evil are:
- Trusting a Particular Minion Too Much: The villain may have a minion that they trusted like family, but he/she failed to see the said union's treachery, whether due to the said minion being a spy from the hero's side or a power hungry character that worse than the villain him/herself.
- Overestimate Goodness: Some villains may have done horrible things or evil so much that they see various forms of goodness (ex. love, friendship, etc.) as useless red tape that should not taken seriously, which turned out to be their downfall as the hero managed to triumph over him/her due to strengthened by support from the said hero's loved ones and friends. Not only that, the villain may also not taking any serious precautions to dealing minions whom turned against him/her due to either their loved ones being threatened or clashing view about goodness. Had the said villain not comprehend how goodness can keep the heroes forward, the downfall won't surprisingly be disastrous.
- Enjoying The Hero's Suffering Too Much: The more sadistic villains may see the hero's suffering as fun, even so far to ruin his/her innocence for greater pleasure, but the said pleasure resulting them lower their guards, unaware that torments that they done instead made the hero become more dangerous, particulary if the said torment strengthened whatever resolve that they had. In other case, the hero allowed themselves to be tortured so the villain would be too distracted from handling anything else.
- Armed a Captured Hostage: Some villains who held a hostage may later proved either too arrogant or simply an idiot who doesn't know how to ensure their said hostage from becoming a threat as bad as heroes who tried to rescue him/her. These villains may either experimented on the said hostage by gave him/her powers against his/her consent, locked him/her near their weapons/gadgets cache, or put an armed weapon near him/her that will active and killed them if they wished to. But if the said hostage unexpectedly turned their given powers/weapons/gadgets against these villains while the hero still looking for him/her or occupied in the fight against them, this proved to be their undoing. This form of mistake would be embarrassing had most of the credit for defeating these villains given to their hostages.
