So you're an aspiring OmnicidalManiac, [[HowToInvadeAnAlienPlanet alien invader]], or plain old disgruntled MadScientist or EvilSorcerer and want to destroy the planet Earth, or at least KillAllHumans? Good for you! However, to avoid being a gauche GenericDoomsdayVillain, why not get yourself a proper motivation to destroy humanity from among the items on this list?

# Because HumansAreTheRealMonsters.
## [[HumansAreWarriors Humans are warlike]], and it's better to [[KillEmAll kill 'em]] [[DoUntoOthersBeforeTheyDoUntoUs before they kill you!]]
## In point of fact: [[Series/BabylonFive They killed your leader!]]
## Not only that, they have a [[Literature/EndersGame school in space dedicated to teaching kid geniuses how to destroy you]].
## Because [[HumansAreCthulhu humanity poses a real threat]] to your [[HiddenElfVillage Hidden]] [[OurElvesAreBetter Space-Elf]] [[HiddenElfVillage Village.]]
## Humans are destroying the planet Earth's ecosystem, so [[KillAllHumans killing all humans]] will [[GreenAesop save the planet]]... oh wait, if you destroy the planet, it will also destroy the ecosystem. Well, at least they won't be able to spread like weeds throughout the galaxy, ruining countless other ecosystems.
## [[AbusivePrecursors After creating your race, they've been bad parents.]]
## In fact, they [[TurnedAgainstTheirMasters enslaved]] your [[Series/BattlestarGalacticaReimagined robotic]]/genetic ancestors [[CreatingLife after creating them.]]
## [[InYourNatureToDestroyYourselves They'll destroy themselves anyway]], so why not do it [[strike:humanely]] alienly?
## [[AntiHumanAlliance Because it will help patch up relations with neighboring aliens]].
## Because humans [[ScaryDogmaticAliens are an inferior race]] and their existence disturbs the [[CrystalSpiresAndTogas serenity and peace]] of your [[CantArgueWithElves wise, benevolent, and in every way more advanced culture]]. If you wait too long the humans will be [[ScrewYouElves ungrateful for being shown your obvious superiority]].
## Because a band of bratty teenagers [[Literature/TheTripods found some hand grenades and blew up some of your people]]. Who knows what the rest of them might do?
## Because one human [[Literature/TheLordOfTheRings cut off your finger and stole your ring.]]
## Because a human married an elf princess and [[Literature/TheSilmarillion stole a jewel from your crown]]
## Still another human [[TheChildrenOfHurin killed seventy of your trolls and then insulted you when you interrogated him.]] They're [[HumansAreWarriors a menace!]]
## Worse yet - because they invented [[TVTropesWillRuinYourLife this site]].
## To rid the universe of all traces of [[Franchise/TheHitchhikersGuideToTheGalaxy the worst poetry in the universe, written by Paula Nancy Millstone Jennings of Greenbridge, Essex]].
## Because [[CrapsackWorld their world]] [[ItIsBeyondSaving is beyond saving]].
## Because they even have sites [[HumansAreInsane discussing the reasons for their own destruction!]]
## Because humans are [[HumansAreCthulhu Just Plain Weird!]]
## Because [[ArsonMurderAndJaywalking they invented]] [[FauxHorrific pop music, Disco and Rap]].
## Because they'll destroy the universe with their [[Film/PlanNineFromOuterSpace stupid, stupid minds]].
## Because [[NoBiochemicalBarriers Aliens Are Tasty]], and we need to stop those horrific mutants from expanding and eating the whole galaxy for their amusement.


# Because AliensAreBastards.
## It would bring [[ProudWarriorRace glory to your race]].
## Because [[HumansAreSpecial humanity poses a potential threat]] to your EvilEmpire.
## Because your ten thousand year old empire cannot tolerate any [[{{Traveller}} other race learning the secret of interstellar travel and forming an empire of its own]].
## [[NeglectfulPrecursors After creating humanity, you just want to mess with them.]]
## [[AbusivePrecursors You created humanity to mess with them.]]
## [[AlienVsPredator Because the aliens you planted on the planet eons ago have escaped]], so [[GoneHorriblyWrong kill them before they can spread any further]].
## Because [[HumansAreUgly humans are just plain hideous]].
## Because humans are [[Anime/FutariWaPrettyCureSplashStar too dang noisy]].
## [[VideoGame/{{Iji}} Because other aliens have destroyed every other planet already.]]
## For reasons your [[PunyEarthlings puny mind]] wouldn't [[BlueAndOrangeMorality understand.]]
## Because you are collecting [[GalacticConqueror conquests]].
## For the [[ForTheEvulz pure joy]] of it.
## [[ButForMeItWasTuesday We destroyed]] [[InsignificantLittleBluePlanet an "Earth"?]]
## [[FantasticRacism Because humans are a blight]] [[ScaryDogmaticAliens and the universe must be cleansed of impurity]].
## [[DisproportionateRetribution Because you got a traffic ticket]] last time you visited Earth and are [[HairTriggerTemper real sore about it]].
## Because {{God}} [[TheSilmarillion made you share authority over earth with others]].
## Because your reasons are [[EldritchAbomination utterly incomprehensible]].
## Because humans finally got tired of you [[TheFairFolk curdling their milk and kidnapping their babies]], and have lots of weapons made of [[ColdIron Iron]].
## Because Humans are [[Literature/TheHighCrusade primitive superstitious folk with crude weapons]] They should be [[TemptingFate easy to enslave.]]

# Because Aliens are ''[[EldritchAbomination alien]].'' And [[HordeOfAlienLocusts hungry.]]
## [[ImAHumanitarian Humans]] taste [[ToServeMan yummy.]]
## [[PlanetEater The Planet Earth tastes yummy.]]
## [[{{Starcraft}} Their planet is contaminated by another alien species]].
## Because Earth is [[SarcasmMode clearly]] a hideous DeathWorld with a poisonous atmosphere and creatures nothing short of {{Eldritch Abomination}}s. It is [[StarfishAliens your race's]] ''[[NecessarilyEvil duty]]'' to eliminate this terror from the universe.
## Because humans (or their [[OurSoulsAreDifferent souls or something]]) [[PoweredByAForsakenChild make a good power source]], say perhaps because your race can [[Anime/PuellaMagiMadokaMagica harvest the energy of their emotions]] by engaging in vaguely [[DealWithTheDevil Faustian]] bargains with humans, and destroying the Earth is the fastest way to get all all those little emotions.
## Because you want to [[TheGreys kidnap other races]] for your [[MadScientist experiments]] and if Earth is still there they will just run away back home; [[HumansAreSpecial humans are difficult]] to keep locked up after all.

# [[OmnicidalManiac Because You Can.]]
## Because [[BreakTheCutie you had a bad day]], [[TheWoobie everyone hates or bullies you]], and [[GodIsEvil God]] and [[CrapsackWorld the world]] are [[TheChewToy bent on making you suffer,]] while being unable to commit suicide alone, and [[WoobieDestroyerOfWorlds the only way to make it stop is]] [[SuicidalCosmicTemperTantrum subjecting all to euthanasia]]. ''Waaaaaah!'' Or getting [[ThereAreNoTherapists therapy]], but that's expensive.
## ForScience! ... or because everybody expects you to.
## [[WesternAnimation/LooneyTunes Because it obstructs your view of Venus.]]
## Because it's in the way of a [[Franchise/TheHitchhikersGuideToTheGalaxy hyperspace bypass]].
## Because you need to create a hyperspace shortcut so [[WesternAnimation/JusticeLeague you can attack your enemy's homeworld directly]].
## Because [[TheyCalledMeMad they called you mad]]. You'll show them, '''YOU'll SHOW THEM ALL!!!'''' Muwahahahahahaha!!!!! They may not have been wrong, though...
## Because [[IfICantHaveYou if you can't have it, nobody will]]!
## Because [[KatamariDamacy you had too much to drink]]. Admit it, already!
## Because it's [[ButForMeItWasTuesday Tuesday]].
## Because you're bored and [[PastimesProvePersonality need something to do]] . I think everyone should destroy a planet at least once. [[EvilFeelsGood It is so invigorating]].
## Because [[NietzscheWannabe life is meaningless, morality a sham and love, hope and dreams are illusions of a deluded mind!]] Therefore the only worthwhile purpose left is to destroy everything and [[SuicidalCosmicTemperTantrum put an end to the pointless suffering that is existence!!!]]
## Because [[TheFettered life is important, morality absolute, and love, hope and dreams the most important things in the universe.]] [[UtopiaJustifiesTheMeans And Planet Earth is in their way.]]
## [[TabletopGame/{{Warhammer 40000}} Because you ran out of other stuff to fight.]]
## Because you are [[VictoryIsBoring bored conquering other races]], you are [[ChallengeSeeker seeking a challenge]] and earth contains the [[HumansAreWarriors only race in the galaxy]] worth the bother of destroying.

And of course, it's absolutely possible to [[MikeNelsonDestroyerOfWorlds destroy the planet Earth, or some other world, purely by accident]].
