->''"I think her bad guys are badder than my bad guys."''
-->-- '''Echo''', ''Series/{{Dollhouse}}''

The hero is in a situation with two unpleasant alternatives and [[SadisticChoice no other options]] are available to him. Begrudgingly, he holds to his moral code and chooses the lesser of two evils.

Compare BlackAndGrayMorality, when those who are technically the "good guys" are the lesser evil.

Not to be confused with ALighterShadeOfBlack, which at least provides a side to root for. (Those stories usually involve a villain's P.O.V. fighting the other side.)

* ''LastExileFamTheSilverWing'': Liliana joins Luscinia and his plans after realizing that even though he is bent on conquering the world and killed her father, killing him will only makes things worse since his death will lead to a massive civil war in Ades over his position and the Exile nations will use that war to their advantage to grab power.

* In one CarlBarks story, Donald Duck chooses to leap into a pool of sharks rather than confront Daisy and her sewing friend [[ItMakesSenseInContext about the crochets he made.]] He cites this trope word to word.
* {{Defied| Trope}} in ''ComicStrip/TheBoondocks'', when Huey is knocked on his behind by his reflection for daring to side with a Democrat(John Kerry) just because he is slightly better than his Republican opponent (George W Bush).

[[folder:Fan Fiction]]
* ''FanFic/DungeonKeeperAmi'': The Shining Concord Empire, Avatar of All Light, King Albreight, and many other lesser overworld powers breifly ally with [[spoiler: Empress]] Mercury for the battle of Crowned Death's high temple. This is actually a case of subversion, as Mercury is a heroine. However, most of the lightworld powers involved do not know or do not acknowledge her as a hero and see it as PragmaticVillainy on her part- she was at war with Crowned Death; and, having discovered the massive, mobile fortress, needs their help to destroy it.
* ''FanFic/AnUnsungSong'': To help the Capitol or [[spoiler:District Fourteen]]?
* ''FanFic/TheImmortalGame'': This is pretty much the justification for [[spoiler: allying with Discord]] in order to defeat [[BigBad Titan]]. As [[spoiler: Celestia]] puts it, they've dealt with the former before, and besides, "better the devil you know".
* The ''FanFic/PonyPOVSeries'': At one point during the [[BadFuture Epilogue timeline]] (about five hundred years prior to the "present" of the Dark World arc), [[WesternAnimation/MyLittlePonyAndFriends Grogar]] returned from his [[SealedEvilInACan imprisonment]] and [[EvilVersusEvil went to war with Discord]] for control of Equestria. During this war, many of Discord's enemies allied with Grogar, as they figured that his "[[LawfulEvil perfect order]]" would be preferable to Discord's "[[ChaoticEvil perfect chaos]]". On the other hand, some did remain with Discord because they saw ''him'' as the lesser evil.
* ''FanFic/QueenOfShadows'': Jade, stuck in the life of the Queen of the Shadowkhan, knows that she's expected to restart the paused war with the human territories of Japan, and if she doesn't she'll blow her cover. So she devises a war plan that she hopes will minimize human casualties and give the heroes she believes are at Tobe a chance to defeat the Shadowkhan.
* ''FanFic/CastlevaniaNocturneOfRuin'': When Walter Bernhard is resurrected and intent on taking back his power base from {{Dracula}}, {{Alucard}} quickly decides that it would be better for Walter to die and Dracula to remain in power; as evil as Dracula is, he kills with definitive planning and is nowhere near as depraved as Walter, who kills people for fun and plays sick games with his victims.

[[folder:Film]]
* ''Film/FreddyVsJason''. With ''two'' nigh-indestructible killing machines on the loose in Springwood, the heroes [[EvilVersusEvil pit them against each other]] and root for the guy who just wants teenagers to keep their booze and premarital sex out of Camp Crystal Lake, rather than the sadistic child murderer who can hunt people anywhere in the world so long as they're asleep. (The big irony here is, Jason's kill count in the movie was higher than Freddy's. Still, it's a valid point.)
* Used as a ChekhovsGag in ''Film/MasterAndCommander'' when Jack forces Stephen to choose between the lesser of two ''[[{{Pun}} weevils]]''. It sets the whole CommandRoster apart from Stephen [[LamePunReaction laughing uproariously]]. [[spoiler:Gets a CallBack later in the movie when Jack has to sacrifice a man who went overboard to keep the ''Surprise'' from being dragged under by debris from a broken mast.]]

[[folder:Literature]]
* Roughly half the plot of ''Literature/TheDresdenFiles'' consists of dealing with these. In particular, "Gentleman" Johnny Marcone (a very powerful, cunning, and ruthless gangster) and Lara Raith (the ''de facto'' leader of one of the three Vampire Courts) fully qualify as evil despite both having moments of sympathy, but Harry Dresden and co. end up allied with them more often than not, if only because they're forces of stability who have no use for the wide-scale destruction many of the ''real'' villains have planned. Harry still doesn't trust either of them near as far as he could throw them[[note]]He knows telekinesis spells. [[MrT He can throw a fool hella far.]] (which is wise, since both are certified [[ManipulativeBastard manipulative bastards]])[[/note]].
** In ''Literature/{{Changes}}'', [[spoiler:Harry needs a power boost to save his daughter. While he could [[DealWithTheDevil summon Lasciel's coin and become a Denarian]] or [[YourSoulIsMine absorb a few hundred thousand souls by performing the Darkhallow]], he goes with the least evil option: he becomes [[TheFairFolk Queen Mab's]] Winter Knight.]]
* A major theme of the ''[[Literature/TheWheelOfTime Wheel of Time]]'' series is people having to learn to work together against a common enemy: many, if not most, of the various nations, organisations and political factions are morally questionable at best, but against an EldritchAbomination trying to undo reality you take what allies you can get.
* In ''Literature/VorkosiganSaga'', Prince Serg is so [[UpToEleven outrageously]] [[TheCaligula psychopathic]] that his father considers it necessary to both start an unprovoked war and then lose it deliberately just so Prince Serg and his supporters can be killed in the process.
* In ''Literature/KillDecision'', Odin uses this to defend his tipping off an insurgent leader to an impending airstrike, explaining that the guy is a moderate compared to his rivals and would-be successors and would fight other foreign extremists and drug dealers once the West gets out of the way.
* In ''Literature/TheManInTheHighCastle'', at least some factions of the Nazi Party are depicted as more reasonable than the leadership, and oppose its genocidal plans [[spoiler:such as wiping out the Japanese.]] And that reasonable faction is Heydrich and the SS, who already are genocidal maniacs in their own right. Faced with the SadisticChoice of either supporting the SS rise to power or watching [[spoiler:his homeland be exterminated]], Mr. Tagomi has a bit of a HeroicBSOD moment.

[[folder:Live-Action TV]]
* ''Series/SevenDays'': Let the world be destroyed, or give the psycho the keys to the time machine?
* ''TheFinder'': A mafia boss hired the heroes to find a voodoo doll to end a curse against him. The trope was invoked out of fear an EvilerThanThou boss would take over.
* Subverted in ''Series/{{Supernatural}}''. Lucifer the archangel is released in season 5 and starts the Apocalypse, and the Winchesters are stuck in a battle between Hell and Heaven. The demonic armies want to destroy the Earth and take over Heaven, [[spoiler:although Lucifer plans on killing them too]], while the angelic bureaucracy is barely better, being a corrupt military theocracy who want to bring about Paradise and [[UtopiaJustifiesTheMeans find the slaughter of half of humanity in the ensuing fight between Lucifer and Michael acceptable losses]]. The Winchesters are too powerless to kill either of them, and after being stuck between two bad options for an entire season Dean almost gives in to Heaven's demands, but the team pulls him back and they continue [[TakeAThirdOption looking for more options]].

[[folder:Videogames]]
* This is a focal point to the plot of ''VideoGame/TalesOfSymphonia''. The main character, Lloyd, is an idealist. His friend, Colette, must [[spoiler:sacrifice herself in order to save her world]]. Most of this game's struggle involves [[TakeAThirdOption finding a third option]].
* In the first two ''VideoGame/GoldenSun'' games, the object is to [[spoiler:restore alchemy to the world]]. Though the main characters understand that this will bring war and strife back to the world, they do this out of necessity because otherwise, [[spoiler:the world will decay]].
* In the second chapter of the original ''VideoGame/AgeOfEmpiresIII'', after Stuart Black is kidnapped, John Black, Kanyenke and Nonakhee are involved in the SevenYearsWar. They have to choose between the britons and the frenchs. They choose the french side.
* In ''VideoGame/{{Starcraft}}'' ''Brood War'', Jim Raynor and his allies side with Kerrigan against the Earth Directorate forces poised to conquer the sector. This is a case where the good guys misjudged which evil was the lesser one.
* ''VideoGame/LegacyOfKain'': [[spoiler:Raziel]] allows himself to be absorbed into the Reaver rather than be the Elder God's captive for the rest of eternity. He's a prisoner either way, but one of his prisons can do more good than the other.
* In ''VideoGame/MetalGearSolid4GunsOfThePatriots'', Snake tries to stop Liquid from taking over the system. He would have total control over pretty much the whole world. Given how much of a nut he's proven himself to be, the protagonists feel that at least [[AncientConspiracy The Patriots]] give the world more stability than Liquid would.
* In the second ''VideoGame/BaldursGate'' game, the player at one point must ally with either the local guild of ruthless thieves and murderers, or the invading unholy vampires. Every good character, even the paladin Keldorn, is grudgingly willing to ally themselves with the thieves, but many leave the party if the player goes for the vampires instead. Though it is possible to go with either, the former is clearly regarded as this trope in the game.
* In ''VideoGame/PokemonRubyAndSapphire'' there are ''two'' evil organizations, Team Aqua and Team Magma. The player opposes one (whose plans threatened to destroy the world) and allies with the other (who is trying to prevent it). Which is which depends on which game. That doesn't mean that your allies aren't evil however, they just aren't ''currently'' involved in any evil plans (This is emphasized in the third game, ''Pokémon Emerald''.) Thus, in this case, the LesserOfTwoEvils is the team you ally with.
* ''VideoGame/KidIcarusUprising'': As much as [[GaiasVengeance Viridi]] is convinced that HumansAreBastards, she nonetheless considers the Underworld Army to be even worse.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/TransformersPrime'': Siding with [[spoiler:Megatron against Unicron]].
* ''MidnightPatrol'': The heroes decided [[BigBad the Nightmare Prince]] was this to Count Bubba Bonebreaker.
* In ''WesternAnimation/PinkyAndTheBrain'', the Brain had an ArchEnemy named Snowball. Described by Pinky as a "genetically enhanced evil hamster dedicated to... well, ''evil''," Snowball also wanted to TakeOverTheWorld, but his plans for it once he did so were much worse than Brain's.

[[folder:Web Originals]]
* ''MarcMues'': Invoked in the eponymous video series where two horrible musicians are compared to each other.
