->''"And the light shineth in darkness; and the darkness comprehended it not."''
-->-- '''[[Literature/TheFourGospels John 1:5]]''', ''Literature/TheBible''

This is when the villain has developed a [[EvilPlan devious plot that is prepared for anything]] the hero might do--except for [[SpannerInTheWorks one glaring flaw]]. For some reason, the villain has not considered the possibility of a HeroicSacrifice. After all, you'd never catch ''him'' throwing his life away to save a bunch of lazy, ungrateful civilians who don't care about anybody except themselves. Heck, even saving your TrueCompanions comes after [[ItsAllAboutMe saving your own life]]. Only an idiot would throw his life away like that--and only because he didn't realize how much more profitable saving it would be. Sometimes that PR would be bad, but [[WhatYouAreInTheDark you only have to get him to where he can act secretly]] to get it out of him.

Too bad for the villain that MachiavelliWasWrong. Why do villains have so much trouble understanding good behavior?

[[TheHero Our Hero]] goes and makes the HeroicSacrifice anyway, thereby ruining the villain's plan with a DidntSeeThatComing that a more cunning villain really should have seen coming. This is one of the ways those with HonorBeforeReason can continue to defeat the BigBad. This is a major problem for villains who really believe they are NotSoDifferent and think heroes [[YouCouldHaveUsedYourPowersForGood could have used their powers for Evil]], as opposed to villains who are just [[BreakingSpeech screwing with the Hero's head]].

Occasionally, greater {{justifi|edTrope}}cation is provided by having a hero who the villain knows is a {{Jerkass}} and the AntiHero decides to [[RedemptionEqualsDeath redeem himself]] at the critical moment, or the villain will meet a hero who decides to TurnTheOtherCheek instead of fighting back.

The inability to comprehend good altruistic behavior ([[NoGoodDeedGoesUnpunished especially when it results in punishment]]) is a common trait in [[TheCynic cynics]], {{Straw Nihilist}}s, {{Corrupt Corporate Executive}}s, {{Social Darwinist}}s, and [[TheSociopath sociopaths]] (who really are incapable of feeling things that have no selfish incentive, such as compassion). This is TruthInTelevision in many cases.

An alternative version involves the Hero giving in to the villain's manipulative demands, agreeing that, yes, WeCanRuleTogether (usually to the horror of his sidekicks, LoveInterest, and TrueCompanions) [[FakeDefector as a ruse]] to defeat the villain. The villain falls for it because it's what he'd have done if the situations were reversed.

{{Greed}}y villains may content themselves with bribing the hero. After all, {{justice|WillPrevail}} and {{revenge}} aren't [[GoldFever shiny]] and don't get a good exchange rate. Yet TheHero goes and turns down the BriefcaseFullOfMoney or a share in the proceeds of a robbery. Similarly, those affected by the GreenEyedMonster often assume that TheHero is equally preoccupied with whatever inspired their envy, and the KnightTemplar does not realize that other people differ about the relative values of what he supports versus what he is willing to sacrifice for its sake. When the Hero interrupts an AttemptedRape, the would-be rapist may propose an easy solution: join in! [[UnstoppableRage Cue heroic beatdown.]]

InnocentBystanders and {{Mooks}} leave the villain even more certain. A DoomedMoralVictor's inspiration or a HeroicBystander will flabbergast these villains, as will a Mook's HeelFaceTurn that is inspired by the hero's example, or a Mook who proves that EvenEvilHasStandards. Indeed, he may help [[VillainousDemotivator the Mook along]] by [[EvenEvilHasLovedOnes threatening their loved ones.]]

Never underestimate ThePowerOfLove and ThePowerOfFriendship. [[TrueCompanions True friendship]] requires acts of kindness and thoughtfulness, which is selfless and understanding. Being self-centered makes it nearly impossible for a villain to understand or embrace the necessary demands of friendship. Pride is by nature competitive, pitting the arrogant villain against anyone and everyone - they simply canít understand ThePowerOfFriendship, which is a form of love, placing it outside of the realm of their understanding. Plus, while the villain may be surrounded by lackeys and toadies whom he keeps them in line via threats or outright violence, the hero has TrueCompanions, love interests and friends who are willing to help them even in dire situations, and enable them to defeat the baddies.

The same thing goes with ThePowerOfLove -- villains would regard it as a bizarre and alien concept, and are completely blindsided when the hero TookAThirdOption to not only save his love interest and allies, but also the city from the villain's clutches. Cue an epic KirkSummation or ShutUpHannibal, where the hero calls out the villain for his crimes, and for his inability to understand compassion or what motivates the good.

WhatIsThisThingYouCallLove [[SillyRabbitRomanceIsForKids Is it just incomprehensible nonsense]], [[CuriosityCausesConversion or should I try to understand it?]] May end in AnAesop that RousseauWasRight and/or SillyRabbitCynicismIsForLosers.

Can be played for laughs if the villain in question does a HeelFaceTurn and becomes a HeroWithAnFInGood.

A favored ethical position of Socratic and Platonic philosophers, who hold that goodness ''is'' wisdom and understanding and that no-one does evil simply ForTheEvulz. In other words, evil does not so much fail to understand good as it can only be evil at all ''because'' it fails to understand good.

The GodOfEvil, {{Satan}}, or other beings that are MadeOfEvil are normally shown as being incapable of understanding things like compassion or goodness. In this case, pure evil cannot understand something that their nature renders them unable to experience themselves. This is OlderThanFeudalism: ''Literature/TheBible'' often depicts the Devil in this fashion, where he's unable to appeal to anything other than selfish desires when manipulating humans. This is often the reason a DealWithTheDevil fails; the deal maker's inability to understand good leaves a loophole that someone who can is able to take advantage of, or simply offer something that doesn't truly matter to the target.

Contrast ItsAllAboutMe; when the villain expects the hero to behave not selfishly, but generously toward him. When the trope is Evil Cannot Comprehend Good, the villain can't understand why the hero saved him from falling; in ItsAllAboutMe, the villain can't understand why the hero insists on arresting him after. It can get a little fuzzy when the character decides to be generous: did he murder his son's romantic rival because he didn't realize his son would hate it--this trope--or because he was so caught up in the notion of his own generosity that he didn't care what his son thought--It's All About Me?

Also contrast VirtueIsWeakness, where the villain actually ''does'' comprehend what goodness entails, but sees it only as a weakness in others to be exploited.

Supertrope of BewareTheHonestOnes and subtrope of WrongAssumption. Contrast GoodIsOldFashioned, SillyRabbitIdealismIsForKids, and the InvertedTrope of GoodCannotComprehendEvil. Compare BlueAndOrangeMorality. Often involves PsychologicalProjection. When someone evil ''is'' capable of understanding or admiring good, it may lead to SympathyForTheHero. If this trope is at work because the villain thinks ''he'' is the good guy and is baffled at the heroes wanting to stop him, it's because he's ObliviouslyEvil. CuriousQualmsOfConscience could be similar to a milder form--characters who doesn't understand the good and the conscience within themselves.
