'''Basic Trope''': A villain engages in evil purely for its own sake.
* '''Straight''': [[BigBad Emperor Evulz]] commits various acts of villainy and dog-kicking without any rhyme or reason, the only explanation being because he ''can''.
* '''Exaggerated''':
** Evulz [[DystopiaJustifiesTheMeans plunges the universe into a living Dystopia only for the sake of perpetrating Dystopia itself, even when everybody including himself suffers in it]]
** Emperor Evulz is always running a colossal XanatosGambit, and generally goes about his goal like a MagnificentBastard. The objective? Bring pain and misery to every possible being in the planet, all for his enjoyment's sake.
** StupidEvil
* '''Downplayed''':
** Bob is a jerk who does things like littering and petty theft for no reason.
** Bob acts a jerk because he likes annoying people.
* '''Justified''':
** Evulz is the AnthropomorphicPersonification of evil or otherwise [[MadeOfEvil made entirely and unrepentantly evil]] [[AWizardDidIt by magical means]].
** Evulz is a [[TheSociopath sociopath]] or {{sadist}} or both.
** Evulz likes to hurt others because it makes his life look so much better in comparison.
* '''Inverted''':
** Bob [[GoodFeelsGood does something heroic because it's good.]]
** ForHappiness
** ForGreatJustice
* '''Subverted''':
** Evulz claims to be doing evil for its own sake, but actually has much more mundane motives for his EvilPlan.
** ItAmusedMe
* '''Double Subverted''': Evulz is captured and explains the logical reasons for doing the horrible things he did... but towards the end of his confession, we find out his underlying goal: to maximize the amount of suffering he's inflicted.
* '''Parodied''': Evulz' sporadic acts of gratuitous villainy never go beyond [[PokeThePoodle minor annoyances and ridiculously innocuous felonies]].
* '''Zig Zagged''': Evulz cares for orphans deeply and loves them all, but still blows up orphanages because he loves to see explosions. However, he led all the orphans out first and that orphanage was an unstable building that needed to be demolished. Blowing up the bus all the orphans were on, however...
* '''Averted''': Emperor Evulz has a fairly logical motive, like money.
* '''Enforced''': "How do we make our bad guy truly evil? Let's make him a sadist!"
* '''Lampshaded''':
--> '''Bob''': How does killing people at random accomplish anything? \\
'''Evulz''': Killing is evil and therefore ''evil'' was accomplished.
* '''Invoked''': Evulz ''doesn't'' blow up orphanages, but Bob mentions that he knows so little about Evulz that he may well do so.
* '''Exploited''': Emperor Evulz, a [[TheChessmaster Chessmaster]] with a greater plan in mind, sets up a simple yet baffling crime as a distraction for his enemies.
* '''Defied''':
** Emperor Evulz declares that he's ''not'' a sadist who does heinous things for his own amusement; he's either a WellIntentionedExtremist, a villain who has [[EvenEvilHasStandards standards]], or someone who prefers to engage in PragmaticVillainy.
** Bob refuses to do evil things even if he thinks that evil things are automatically fun just by "virtue" of being evil.
* '''Discussed''': "How do I know if he's lying about why he did it or is just plain crazy? Sane people don't have goals like 'murder as many people as I can'; there's always at least some claim to the moral high ground."
* '''Conversed''': "Why does it seem like all of the villains in that show seem to lack a coherent motivation besides 'kill as many people as possible'?"
* '''Deconstructed''':
** It goes to show how insane and messed-up Evulz is.
** Evulz has no redeeming characteristics whatsoever that will make him justifiable and appealing to any faction, thus the heroes and well-intentioned extremists are free to team up and do whatever it takes to destroy him.
* '''Reconstructed''': But even if he [[CombatSadomasochist enjoys others' sufferings, he also enjoys his own]].
* '''Played for Laughs''': Evulz, obsessing over wanting to do as much evil as possible just for the sake of evil itself, steers far into StupidEvil territory.
