[[caption-width-right:350:Perhaps they want a pet snake? [[note]] An illustration of La Fontaine's fable by Ernest Griset[[/note]]]]

->''"One winter a Farmer found a Viper frozen and numb with cold, and out of pity picked it up and placed it in his bosom. The Viper was no sooner revived by the warmth than it turned upon its benefactor and inflicted a fatal bite upon him; and as the poor man lay dying, he cried, 'I have only got what I deserved, for taking compassion on so villainous a creature.'"''
-->-- ''Literature/AesopsFables'', "[[http://books.google.com/books?id=jsfMkK8JL9QC&printsec=frontcover#PPA121,M1 The Farmer and the Viper]]"

''[[AnAesop Kindness is thrown away upon evil.]]''

What's this? An orphan has appeared near the HauntedCastle, or an addled [[TheDrifter drifter]] in need of help wanders into town, or perhaps an outright villain is shown {{Forgiveness}} and compassion once they've lost, and they are taken into a GoodSamaritan's home and shown kindness. But in the middle of the night, the benefactors awaken to find the good silver stolen, the dog dead, and the house on fire -- all courtesy of the injured person they thought they could help.

They should have known better.

This FamilyUnfriendlyAesop is much like CuriosityIsACrapshoot: a display of [[ThePowerOfFriendship friendship]], [[PowerOfTrust trust]], and [[ThePowerOfLove love]] won't always bring about [[LoveRedeems redemption]]; sometimes a bad person is simply bad, and they won't stop being that way just because you were kind to him--in fact, they may very well betray you in any number of fashions, [[NoGoodDeedGoesUnpunished repaying the good turn you've done for them with evil]]. It's in the nature of a snake to bite, after all.

Expect this to be used both straight and subverted or played with when works mirror the tendency in RealLife for people to use this as an excuse to not act charitably towards those in need, stereotyping someone (typically someone they haven't met or have only interacted with briefly) with bad traits associated with a label or group that they belong to (or appear superficially that they belong to) so as to make the case that they either don't "deserve" help, are dangerous to help (or that the person who helps them will be rewarded with unkind behavior in return), or, in extreme cases, to justify cruel, unlawful or evil acts against them. This could be anything from not giving a beggar money because "they'll spend it all on drugs" to a serial killer choosing to murder prostitutes (or women dressed skimpily) because "they're wicked sinful whores who deserve to die." In a variation, it isn't uncommon in police procedurals to come across a killer who believes that by killing or sacrificing people of a certain group in a ritualistic way, they are acting mercifully or fulfilling some religious belief, following similar reasoning - e.g. "cleansing them of a miserable or evil existence". On the other hand, playing this trope straight is a great way to establish a villainous character having passed the MoralEventHorizon in a short amount of time.

Compare MoralityChain, where the Samaritan ''does'' somehow manage to restrain their ward's wickedness. TurnTheOtherCheek is probably the Samaritan's mindset. The receiver may turn out to be AlwaysChaoticEvil, a BitchInSheepsClothing or a JerkWithAHeartOfJerk. When combined with SaveTheVillain, this is sometimes used to set up a DisneyVillainDeath. Compare BadSamaritan, when it is the care-giver, not the care-receiver, who is evil. Also compare ComplainingAboutRescuesTheyDontLike. Plays with the traditional belief of SacredHospitality.

Inverse of GoodSamaritan and AndroclesLion. See also BefriendingTheEnemy, NaiveAnimalLover, SaveTheVillain, TakingYouWithMe, TakeMyHand, PrisonersDilemma, UngratefulBastard, ChronicBackstabbingDisorder, HorribleJudgeOfCharacter. Compare PacifismBackfire (while this is "Hospitality Backfire") and the FalseInnocenceTrick where a captured villain pretends to be harmless. See also TheyWereHoldingYouBack for a common justification for how the viper is really "helping."

Also called the "Scorpion Dilemma", or "The Scorpion and The Frog" after a similar fable. Not to be confused with [[Theatre/{{Oklahoma}} "The Farmer and the Cowman."]] See also OrcRaisedByElves.




[[folder:Anime and Manga]]
* In a later episode of ''Manga/{{ARIA}} the NATURAL'', Akari spots a woman who is dressed like she's just gotten back from a funeral. She is then told a ghost story about a woman in black who asks for transport, then spirits her gondolier away. That night, the woman in black asks Akari for a ride to a graveyard. Akari takes her (This is notably not the only example of TooDumbToLive, because the anime consistently encourages naivety). Akari goes on her way, but the woman, in a weird subversion, grabs her hand and tries to spirit her away, specifically ''because'' she was impressed with Akari's kindness. The anime implies this to be a bad thing, but never makes it really clear. [[spoiler:Cait Sith saves her, though, so we never find out.]]
* Not quite a straight example: in ''Anime/CodeGeass'', Lelouch uses his [[CompellingVoice Geass]] to steal a [[HumongousMecha Knightmare Frame]] from a Britannian soldier named Villeta Nu. He leaves her alive, the Geass clouding her memory but still leaving vague echos that lead to Villeta [[spoiler:causing the death of Lelouch's friend/possible love interest Shirley and screwing him over by revealing his identity ''twice''.]]
* ''Anime/DragonBallZ'':
** During the fight with Raditz, Goku [[AchillesHeel grabs Raditz's tail]] to give Piccolo an opening to kill him with the Special Beam Cannon. Raditz begs Goku for mercy, promising to leave Earth if Goku does so; over Piccolo's protests, Goku grants Raditz's mercy... and Raditz promptly knocks Goku down and ruthlessly breaks his ribs, all while rubbing in his face how stupid it was of him to fall for it. When Gohan critically injures Raditz and Goku has him restrained so Piccolo can finish him off, Raditz tries the same trick again; unfortunately for him, Goku isn't dumb enough to fall for the same ploy twice.
** When Frieza is [[HoistByHisOwnPetard bisected by his own attack]] and begs Goku for help, Goku, after some debate, transfers a portion of his energy to Frieza to at least allow him to escape Namek's explosion. Frieza responds by openly mocking Goku and then, unable to accept his defeat, uses that very energy for one last-ditch attack; by this point, Goku has lost all patience with Frieza [[BackstabBackfire and blows him away.]]
* The myth of the frog and scorpion is heavily [[DiscussedTrope discussed]] during the second half of ''Edens Bowy''. The plot involves TheHero and TheRival being two of the only God Hunters in existence, two {{Floating Continent}}s warring heavily to get their hands on the Hero, protected by an Angelic MacguffinSuperPerson who is responsible for said Hero's realization of his true nature. Much agonizing and angsting were had to contemplate inevitability of one's role; namely, must the hero surrender to his nature to kill his LoveInterest when she's an Angel, even though she's responsible for his survival so far? The resolution to this is... complicated.
** Interestingly, during the WhereAreTheyNow epilogue, said rival now earns his keep by telling the tale of the scorpion and the frog, with his own twist at the end.
* In ''Manga/FistOfTheNorthStar'', Jagi's backstory has him almost being killed by Kenshiro, who changes his mind at the last second and spares him. Instead of repenting, it just made Jagi even worse, and he receives no mercy the next time they meet.
* In the first ''Anime/FullmetalAlchemist'' anime, the disgraced and homeless [[TheChewToy Yoki]] is taken in by a group of Ishbalan refugees. He promptly betrays them by selling out the SerialKiller and fellow Ishbalan Scar to a bunch of bounty-hunters with the intent to split the bounty. The refugees don't take the idea of Yoki ratting out one of their own well and promptly give him a beat-down. Averted in ''[[Manga/FullmetalAlchemist Brotherhood]]'' and the [[Manga/FullmetalAlchemist manga]].
** Also Scar himself, after he [[spoiler:kills Winry's parents after they give him lifesaving medical treatment, To his credit it was a bit accidental but still he managed to kill both.]] ...[[MultipleChoicePast depending on the source material]]. In the first anime, it was Mustang being forced to do his job.
** In the later chapters, [[spoiler:the chimera Zampano]], one of Edward's allies that Ed previously spared in battle, sneaks off and contacts [[spoiler:the Military high command]] to rat them out. It's all a [[spoiler: BatmanGambit though, planned to draw one of the homonculi to them so they can spring an ambush.]]
* ''Franchise/{{Gundam}}''
** Subverted in ''Anime/MobileSuitGundam00''. After defeating Ali Al-Saachez, destroying his Gundam Arche and cornering him in a hallway, Lockon Stratos gives the man who killed his family one last chance at redemption. True to form, Ali whips out a gun while Lockon's back is turned...[[spoiler:and is shot dead before he can pull the trigger.]]
** ''Anime/MobileSuitGundamSEEDDestiny'': poor, poor Shinn. The only way to save [[spoiler:Stella]] was to send her back to Neo, the only one who has the medical equipment to save her. He promised to keep her far from battlefields. What happens next? [[spoiler:Neo puts her into the cockpit of the Destroy. Then Kira has to kill her to stop the destruction of Berlin.]]
*** Yzak and Deerka are a curious example. Chairman Durandal saved them during their trial for war crimes. But in the last episodes, they side with Lacus. So, here we have a VillainWithGoodPublicity saving some anti-heroes, and they bite him back by siding with the true good guys.
* Done during the third season of ''Anime/HellGirl''. A teachers saves a quiet and shy acting girl student from being bullied. Afterwards, the girl's grandmother spends the episode trying to get the teacher fired, out of what appears to be jealously. [[spoiler: Turns out the little girl was lying to her grandmother and claiming that it was the teacher who was bullying her. When the teacher confronts the girl after finding this out, the quiet girl just smiles and claims [[ForTheEvulz because it's fun]].]]
* Sets up the plot in ''Manga/JojosBizarreAdventure'', with George Joestar and his son Jonathan as the Farmers and Dio Brando as the Viper. George and Jonathan's kindness costs them their lives, leads to countless other deaths, and nearly causes the end of the universe. Contrasts to Speedwagon whom was in a similar situation but when Jonathan spares him he becomes a life long (and beyond) friend and ally to the Joestar family.
* In ''LightNovel/KinosJourney'', Kino saves some stranded traders. It then turns out they trade human slaves and are looking to recuperate their losses.
* In ''Anime/MegaloBox'' Nanbu is likened to a scorpion, with the implication that Nanbu is the sort of person who continues to betray and selfishly use others for his own ends. The whole story gets told in episode 10, [[spoiler:after TheReveal that Nanbu's plan was to get Joe into Megalonia and then fix one of his matches to make money]].
* Johan Liebert from ''{{Manga/Monster}}'' kills his foster parents -- [[SerialKiller many pairs thereof.]] Anyone who ever does anything ''remotely'' decent or nice for him ends up as the farmer to Johan's viper, but Tenma, the one who saved his life in the first place, gets the very worst of it through the horrible things that Johan does to others in order to "repay" him.
* In ''Manga/OkaneGaNai'', [[HorribleJudgeOfCharacter Ayase]] saves Kanou, only to end up 4 years later as Kanou's love slave.
* In ''Manga/OnePiece'', [[IllGirl Kaya's]] family takes in an apparently down-and-out man and makes him their butler. He is secretly the pirate [[ManipulativeBastard Captain Kuro]], who develops a long-term plan; kill the entire family, steal their fortune, and retire on it.
** Done [[AccidentalAesop likely by accident]] with Aokiji and Robin: Aokiji lets her live in spite of his order from the World Government, but, in spite of his warning to keep out of trouble, she's currently part of a crew whose leader declared war on the World Government.
** Don Krieg and his crew were starving after their fleet was destroyed by Dracule Mihawk. Sanji fed them over everyone else's protests. Don Krieg "thanked" him by attacking him the moment he felt satiated and declared his intent to claim the floating restaurant as his new flagship. Sanji likely knew this would be the outcome, but having nearly starved to death once himself, wouldn't wish such a fate on ''anyone''.
** In the Fishman Island arc, Robin references this trope; when Jimbei asks her to free the slaves Hammond is using for his Slave Tank, Robin is disgusted by what Hammond is doing, but expresses concern that the freed slaves will attack both her allies and enemies, hating Fishman Island after what they've been through. Jimbei says that they can simply fight them off if this happens and that he can't stand [[NotSoDifferent Hody's men acting like the Celestial Dragons]] any longer, persuading Robin to free the slaves, who help the Straw Hats against the New Fishman Pirates.
** Still in the Fishman Island arc, a flashback gives us a variation, in that kindness isn't repaid with ''evil'', but still with unkindness. [[spoiler:After the pirate Fisher Tiger brought the little ex-slave girl Koala back to her home, he was ambushed by Marine soldiers, who knew he would be coming. The reason being because Koala's hometown sold Tiger out to the Marines, in exchange for the Marines not kidnapping Koala again (though the latter didn't know about it); a decision possibly made easier by the fact that Tiger was a fishman. Sure, it's not kind of them to do that, but considering their reasons, it can't be called "evil", and it's pretty hard to blame them.]]
* In ''Anime/{{Pokemon}}'', when the Team Rocket trio got stuck in a cave with Brock and a scientist, they agreed to help each other to get out. When they found an opening they immediately went back into stealing Pikachu.
* ''Manga/RurouniKenshin'': The starving, lonesome little kid Enishi almost dies in the streets of a foreign country (China) until a rich Japanese family saves him, even going as far as letting him stay for however long he needs, no questions asked about his obviously painful circumstances. He slaughters them and takes all their money purely because he was jealous of how happy they were.
* Subverted in an episode of ''Anime/SamuraiPizzaCats''. Bad Bird is about to fall off a cliff, and Speedy grabs him by the arm just before he falls. Bad Bird asks why he's helping him, since he's an enemy. Speedy realizes he's right, and lets him fall. This is especially interesting because Bad Bird ends up being redeemed at the end of the series.
* ''Anime/{{Shinzo}}'': This happens quite a lot; when [[ActualPacifist Yakumo]] shows kindness towards a villain, you can bet they'll try to kill her anyway. Even regular Enterrans will betray her kindness in a second; Yakumo saves an Enterran child, but once the villagers find out she's human, they try to burn her.
* In ''Manga/{{Tsukigasa}}'', a group of robbers save Kuroe's life and have him stay on as their doctor. Five years later he ends up stealing their special maps, running off, giving them to his former friend who is a {{samurai}} so they can be tracked down, and personally killing the two that hunt him down. All because they were going to rob his LoveInterest.
* In ''Manga/VinlandSaga'', an English farmer and her daughter take pity on a young boy who stumble into their cottage, feeding and delousing him and sheltering him from the soldiers who are looking for a Viking spy and are killing all strangers on sight. In return, the boy burns down the village's dock, signaling the Vikings nearby to come take the village, which they do. Said boy is the ''[[BlackAndGreyMorality protagonist]]''.

[[folder:Comic Books]]
* Occurs in a horrifying manner in the ''ComicBook/FiftyTwo'' miniseries set in the year after ''ComicBook/InfiniteCrisis''. Osiris, the brother-in-law of Black Adam, the (sort of) EvilCounterpart of [[ComicBook/{{Shazam}} Captain Marvel]], takes in a lonely anthropomorphic crocodile as a pet/family member whom he names Sobek. For most of the series, Sobek is depicted as a cowardly yet friendly fellow with a [[BigEater huge appetite]]. [[spoiler:He is actually one of the Four Horsemen of Apokolips, {{Eldritch Abomination}}s that hail from Apokolips and given bodies by the {{Mad Scientist}}s that also star in ''52''. "Sobek" is actually Yurrd the Unknown, Lord of ''Hunger'']]. Sobek is a BigEater because [[spoiler:his hunger can only be satisfied with the flesh of a Marvel. He manages to trick Osiris into depowering himself while Osiris is guilt-ridden after accidentally killing an attacker. Sobek ''eats'' Osiris alive; the depiction in the comics is rather horrific]]. When confronted with this by Isis, Osiris' sister and wife of Black Adam, what is the traitor's response?
--> '''Isis''': How could you do this? We treated you like family. We ''loved'' you.\\
[[spoiler: '''"Sobek"''']]: [[ReptilesAreAbhorrent What use is love to a reptile]]? My blood is cold!
* In a ''Franchise/{{Batman}}'' Detective comics storyline, the Joker gets hit by a truck after trying to kill Robin. He gets taken in by a magician who came to Gotham to study its "fascinating" criminal element. The Joker repays his kindness by teaching him some tricks of the trade. Then the Joker garrotes him and [[spoiler:steals his identity to facilitate (oddly enough) a BatmanGambit to get Batman into one of his more clever deathtraps, not that it works. It's the Goddamned Batman]]. The Joker even refers to the "Farmer and the Viper" story while recapping his scheme to Batman.
** Batman and Joker's ''relationship'' is this trope. Batman's refusal to kill Joker because IfYouKillHimYouWillBeJustLikeHim is repaid by Joker's literally killing of thousands of victims.
* In [[Creator/FrankMiller Frank Miller's]] ''ComicBook/HolyTerror'', Amina is a Muslim exchange student who is shown kindness by a young person named Jaye, who invites her to a party. Amina turns out to be an Islamic terrorist and suicide bomber.
* This is the SuperheroOrigin of Freddy Freeman aka [[ComicBook/{{Shazam}} Captain Marvel Junior]], before he became Captain Marvel after ''ComicBook/CrisisOnInfiniteEarths''. Freddy and his grandfather were fishing in a lake when [[StupidJetpackHitler Captain Nazi]] is thrown into it by Captain Marvel in the middle of their battle. Freddy and his grandfather help rescue Captain Nazi, who repays them by killing the grandfather and ''crippling'' Freddy. Captain Marvel shares the power of Shazam with Freddy to save him, turning him into Captain Marvel Junior.
* ''ComicBook/{{Robin|Series}}'': Tim tries to give Damian a second chance after their first meeting consists of Damian trying to blow him up and, though he never truly gives Damian his trust, Damian never truly stops trying to kill him, continuing sabotaging his equipment in potentially fatal ways long after he's mostly adapted to life outside the League of Assassins. Jason the other hand betrays Tim thoroughly. After Tim helps Jason escape from Arkham and gives him access to the Batcave to view his portion of Bruce’s video will Jason seems to be ready to uphold their unspoken truce but later has a complete breakdown over the message Bruce left him and nearly succeeds in killing Tim.
* A variation on the tale itself comes in the Academy Comics' ''{{Anime/Robotech}} II: The Sentinels'' Halloween special, where after going with an Away team against the wishes of his wife Lisa, Rick Hunter explains his actions with the story, basically telling her that he's ''always'' gonna be a little headstrong and willing to take risks. To which Lisa says: "So the moral of the story is you're a lying snake, huh?"
* Played back in forth in a comic for ''WesternAnimation/TransformersAnimated'' where Ratchet is shown helping a Decepticon suffering from "Cosmic Rust", a disease some Decepticons released in the middle of a battle. Ratchet does it on the grounds that while the commanders knew the score for doing such a thing, it's no reason to abandon a soldier. [[spoiler:[[NiceJobBreakingItHero Then it turns out]] the guy ''was'' the one that made the disease, and infects Ratchet with it after being cured. ''However'' in the process they made a cure for the disease that Ratchet was able to take back, and he'll probably be able to save plenty of Autobots if they can manage to replicate it]].
* ''ComicBook/UsagiYojimbo'' also makes use of the "Farmer and the Viper" story when a hapless fisherman rescues [[AxCrazy Jei-san]] [[spoiler:after the latter was stabbed in the stomach and tossed off a cliff into a raging river]] and fails to notice Jei's MilkyWhiteEyes, [[VoiceOfTheLegion ominous voice]], and [[EvilIsDeathlyCold the mysterious chill]] that follows him. Jei even tells the story to the fisherman [[spoiler:right before Jei kills him with his bare hands.]]
* The idea of ThePowerOfLove failing to redeem is featured in ''ComicBook/JohnnyTheHomicidalManiac'', when [[HorribleJudgeOfCharacter Devi]] asks [[AxCrazy Johnny]] on a date. All seems to be going well at first, until Johnny realises that he's found someone who actually makes him feel happy. He then [[spoiler:tries to murder her, the one person who ever showed him any kindness]] in order to "immortalise the moment." This goes to show how completely fucked up his mind is, as well as kill the idea of any more romance in the series. [[spoiler:Devi gets away though.]]
* In ''Comicbook/TheSandman'', Loki's urge to punish Morpheus ''because'' Morpheus helped him escape his eternal torment. Odin even cites this Aesop when pointing out to Morpheus how it is in Loki's nature to repay kindness with malice and ingratitude. [[spoiler: Turns out to be an InvokedTrope on Morpheus's part; Loki's actions are all part of Morpheus's plan.]]
* Loki does it again in ''ComicBook/JourneyIntoMystery'', going so far to lampshade it. [[spoiler:While he keeps reassuring Thor of his good intentions, reciting him the first verses of ''The Scorpion and the Frog'', he still betrays him while telling "I'm no scorpion... for I am Loki!"]]
* ComicBook/TheQuestion recites a version of this parable to himself after he is attacked by a biker who he just saved from a fire.
* {{ComicBook/Deadshot}} references the frog and scorpion version in ''ComicBook/SecretSix'' after apparently betraying the team. [[spoiler: Averted in that he was actually trying to protect the rest of his friends.]]
* In ''ComicBook/SonicTheComic'', Super Sonic was actually Sonic's SuperPoweredEvilSide. During one story they got split apart, and Super Sonic lost both his power and his memory, becoming far more mellow, and befriending a magician called Ebony, who helped him get back on his feet. At the end of the series, Ebony and Super Sonic showed up at the final battle against Chaos, Super Sonic dying as a result of losing his power. Super Sonic absorbed the energy from Chaos, restoring his power... and his former OmnicidalManiac personality. Fortunately, unlike most examples of this trope, he didn't kill Ebony. But she was forced to merge the two Sonics back together to stop Super's rampage.
* ''[[ComicBook/TheBatmanAdventures The Batman & Robin Adventures]]'' features this in an issue called "Dagger's Tale". The title character is relating to when he followed this to a young hotheaded inmate, revealing how when he attempted to break out of prison with an AxCrazy partner it went horribly wrong and said crazy partner decided [[YouHaveOutlivedYourUsefulness their partnership wasn't working out]]. Batman saves Dagger at the last minute. He's astonished for a second ("You-You saved me?!" "I save '''everyone'''."), but after a remembering that Batman had previously gotten him captured in the first place decided to pay him back by attempting to stab him in the back, only to be punched out by the Dark Knight. After finishing things, he urges the inmate to not make a stupid mistake like he did and just serve his time out.
* In Don Rosa's ''ComicBook/TheLifeAndTimesOfScroogeMcduck'', Scrooge encounters an unnamed South Afrikaner ([[spoiler:who later turns out to be a younger Flintheart Glomgold]]) after the mining camp he had been a part of left him for dead for his numerous acts of thievery by tying him to a wildebeast. Scrooge saves his life and even shares his camp with him. The Afrikaner repays him by stealing all his supplies in the middle of the night and leaves him stranded in the wastelands. It's even lampshaded with Scrooge calling the Afrikaner a viper; he had experience dealing with unapologetic crooks, but this kind of betrayal genuinely infuriated him.
* A comic serial on the Tales of KingArthur had the Frog and Scorpion tale being told to justify an EnemyMine situation...up to the point where the frog swims across the river with the scorpion on its back. Later on, the person telling the tale privately reveals the DownerEnding and jokes dryly that the story is a lot better without it.
* In ''ComicBook/BigTroubleInLittleChina'', while traveling the Midnight Road, Egg and Jack ask for directions from a demon woman tied to a tree. Despite Egg's warnings Jack takes pity on her and tries to be nice, and is nearly killed for his trouble.
* In ''ComicBook/{{Arawn}}'', a farmer couple provides shelter for an wandering strange in exchange for work. The stranger repays the kindness by killing the man in his sleep, raping his wife right next to his body and would have sacrifices their children if the woman didn't free herself in time and killed the bastard.
* Used in the [[ComicBook/DisneyDucksComicUniverse Scrooge McDuck]] story ''The Horseradish Treasure'' (September, 1953) by Creator/CarlBarks. Scrooge and the nephews are trapped at sea with their enemy Chisel [=McSue=]. When Chisel seems about to drown, Scrooge contemplates whether he should let him die or not. Against his better judgement, Scrooge rescues Chisel. Shortly after, Chisel attempts to murder Scrooge... by drowning him.

[[TheBadGuyWins She succeeds, too.]]]]
* Occurs in one of the fairy tales told in [[https://www.fanfiction.net/s/5529125/3/Once-upon-A-Fairytale Once Upon a Fairy Tale]].

It seems to work, and Luna eventually restores Falla's lost [[TimeMaster chrono magic]] to give her a chance. As it turns out, Falla was faking a HeelFaceTurn to trick Luna into doing exactly that, and as soon as she does so, Falla [[HalfTheManHeUsedToBe bifurcates Luna]] and proceeds to [[DidYouActuallyBelieve rub in Tsukune and the others' faces how stupid they were to believe that her attempts to reform were ever anything but an act]].
** Kyouko gets hit with this especially hard; as stated above, she tried to show the original Falla kindness and reach out to her, only for Evil!Falla to use her as an UnwittingPawn in her scheme. When she's brought back for a brief period in Act V, Evil!Falla takes great delight in rubbing in Kyouko's face how she just used her before trying to kill her. This ends up biting her in the ass; after everything else that's happened, Kyouko hits her Rage Breaking Point and attacks Evil!Falla, later finishing her off by [[BatterUp beating her to death with a baseball bat]].

* ''Disney/TheLionKing'': Mufasa learns the hard way that being nice to an ObviouslyEvil sibling, who was scheming right behind his back, isn't going to change his heart.

* ''Disney/{{Zootopia}}'': Subverted. While it appears at first that Nick Wilde is the traditional sly, untrustworthy fox when he takes advantage of Judy Hopps' naivete to pull her into his pawpsicle hustle and later delivers a solid BreakThemByTalking speech to her, over the course of the film, it's revealed that Nick was originally as idealistic as Judy until a [[CynicismCatalyst childhood trauma]] caused him to live up to [[ThenLetMeBeEvil the stereotype that society had about foxes.]] His character development arc reveals that his kind and idealistic side still exists, it was just buried and Judy's faith in him helps that resurface.

This is a ploy the father and son had repeated many time before and since, till the boy was able to live on his own.
* The British humor film ''Film/KeepingMum'' has what might be considered a (on the whole) well-meaning (though definitely not good) snake. Grace, the new housekeeper (who happens to be an elderly released murderess) becomes genuinely grateful that the family she has moved in with is happy and grateful she's come, particularly Walter (aka. Mr. Bean). Compounded with her [[spoiler:being Gloria's mother]], she decides to help the family and goes about being a decidedly murderous Mary Poppins to the Goodfellow family. First killing a dog that kept Gloria up, then the owner when he snooped, and finally Gloria's peeping tom paramour because he was causing Gloria to destabilize the family. All in all, she did the family a world of good, however [[spoiler:she may well have unlocked her daughter's murderous side.]]
* In the backstory of ''Film/MirrorMask'', the Queen of Light took in the Evil Princess, who repaid her kindness by stealing the [[MacGuffin charm]] that kept the Queen [[FisherKing and the realm]] alive.
** And let's not forget that after leaving the world of Mirrormask and trapping its creator inside, she was systematically destroying the paintings in the real world that were its [[CosmicKeystone anchor]]. All just to get away from [[MyBelovedSmother smother dearest]].
* ''Franchise/{{Halloween}}''
** In the opening scene of ''Film/Halloween5TheRevengeOfMichaelMyers'', Michael is nursed back to health by a hermit after falling down a mineshaft and being shot repeatedly by local authorities. Then, a year later, he wakes up from a coma and murders the hermit.
** In [[Film/{{Halloween 2007}} the 2007 remake]], when Michael escapes the institution, the only security guard who showed him compassion and kindness throughout his fifteen-year incarceration is given an extremely brutal and over the top murder: tossed around like a ragdoll, head dunked in sink four times, and finally head squashed by thrown TV. In contrast, the other guards, most of whom bullied and demeaned him, are typically stabbed or [[NeckSnap neck snapped]].
* In Creator/TheCoenBrothers film ''Film/MillersCrossing'', Tom is supposed to take Bernie into the woods and kill him for grifting the wrong mobster, but Bernie's constant pleading and weeping convinces Tom to take pity on him and lets him go. Shortly thereafter, Bernie shows up at Tom's home and proceeds to blackmail him by threatening to walk around in public and expose the fact that Tom lied about killing him. While pleading, Bernie even makes the argument that he shouldn't have to die for grifting, because "I see an angle, I take it," somewhat paraphrasing the Scorpion's excuse, "It's my nature."
* In ''Film/TheThiefOfBagdad'', Abu, while stranded on a deserted beach, discovers a bottle. Opening the bottle, he unleashes a huge genie, who because of his imprisonment grew to hate those who lived free and swore to kill his liberator. Abu tricked the genie into returning to his bottle and threatened to toss him into the sea. The genie was then able to regain his freedom by granting Abu three wishes.
* ''Film/TheDevilsCarnival'', which overtly bases chapters of the story on Literature/AesopsFables, uses the Scorpion and the Frog story in several ways. First, one of the female leads dies during a fight with her abusive boyfriend. Once in Hell, she comes across a hoodlum locked in jail, and kindly returns his knife so he can use it to pick the lock and get free. Once freed he convinces her to take part in his "knife throwing act", where he sings a song mocking her before throwing a dagger into her heart. Finally the story is summarized in a second, innuendo-heavy song about a trusting young frog falling for the "prick" of a scorpion's tail.
* A ZigZaggingTrope in the 2000 live-action adaptation of ''Film/HowTheGrinchStoleChristmas''. Here, the Grinch is [[FantasticRacism a green-furred baby who is persecuted throughout his childhood]] and finally driven out of Whoville and up to the isolation of Mount Crumpet, where he grows to maturity. Cindy Lou Who becomes convinced that the Grinch is not completely evil and urges the townspeople to include him in their Christmas festivities. But not only are the Whos unreceptive to this idea at first, but the Grinch himself has become so misanthropic that he does not ''want'' to be treated kindly anymore. Cindy at length gets both sides to change their minds, and the Grinch is made the guest of honor at the Whoville Christmas festival - a position he does not enjoy. Even so, the Whos shower him with kindness and the Grinch grudgingly plays along... until the time of the gift exchange comes and he is awarded a "gag gift" of a razor - an object carrying UnfortunateImplications for him because as a boy he had been mocked by the other children for his green whiskers, and when he tried to shave them off he succeeded only in cutting himself and getting mocked for ''that''; this was the final injustice that drove the Grinch to flee from civilization. His temper boiling over, the Grinch [[TheReasonYouSuckSpeech lectures all the Whos about their hypocritical attitude toward Christmas]] before setting fire to the Christmas tree in the town square and fleeing the scene. But when he discovers that the Whos had a spare tree to continue the festivities, he becomes even more filled with hatred and finally embarks on his mission to steal all the townspeople's present.
* In ''Film/TheLoneRanger'' Tonto's backstory involves him [[spoiler:finding and rescuing Cole and Cavendish from the desert. After being nursed back to health, they proceeded to slaughter his tribe to keep the silver mine a secret]].
* In the Corey Haim B-Movie ''Prayer for the Rollerboys'', Corey plays a homeless teen taking care of his little brother. He runs into an old friend who now runs a powerful roller blade gang. During the film, Corey saves the life of the old friend's dragon which earns him entry into the gang. The dragon thanks him by spending the rest of the film trying to turn Corey's old friend against him. Even {{lampshaded}} during the film itself.
* ''Film/XMenFilmSeries'':
** ''Film/XMenFirstClass'': Charles Xavier believed that he could help the emotionally damaged Erik Lehnsherr find some measure of peace and happiness by offering the latter friendship and a home, but [[spoiler:Erik repays Charles' kindness with betrayal, abandonment, and a permanent (if accidental) spinal cord injury]].
** ''Film/XMenDaysOfFuturePast'': [[spoiler:1973 Magneto's sole contribution to the venture is to derail things the ''moment'' he sees a chance to advance his cause at the expense of everyone else. As the endings of ''First Class'' and ''X2'' show, this is something of a habit for him.]]
* At the beginning of ''Film/TheStepfather III'', a rejected medical doctor gives the titular character face change surgery, only for the Stepfather to kill him after the surgery was done and after he stayed rent free in the doctor's house until he was healed.
* ''Film/{{Dragonheart}}'' began when Prince Ainen's life was saved after he was given half a dragon's heart. He recovered but he turned into a tyrant. Years later his mother told him saving him was the worst mistake she ever did.
* ''Film/BatmanForever'' had the one where Robin saved Two-Face from falling to certain death and he gets rewarded by having a gun pointed at his face and used as a hostage.
-->'''Two-Face:''' The Bat's taught you well. Noble. [''pulls his gun''] Stupid, but noble.
* Near the end of ''Film/SupermanII'', Superman asks Lex Luthor to help him trick Zod, Ursa and Nod into depowering themselves by getting him into a chamber that would take away their powers. Lex ''immediately'' informs Zod to get back into his good graces, despite Zod having turned on him earlier, and Zod promises to give him the ShinyNewAustralia he was asking for all along, Superman is forced into the chamber instead. [[spoiler: Unfortunately for Lex and Zod, Superman ''counted'' on Lex doing exactly that, [[BatmanGambit knowing]] that Lex was a SmugSnake with ChronicBackstabbingDisorder who couldn't help himself, and had rigged the chamber so that it worked in reverse- Superman was protected while ''inside'' the chamber, but Zod and his minions lost their powers because they ''weren't'', leaving Superman the only one with powers again.]]
* The documentary ''Film/GrizzlyMan'' concerns [[TruthInTelevision a real life case of this]]: Animal activist Timothy Treadwell was pretty much in love with [[BearsAreBadNews bears]]; he insisted and believed that he was protecting the bears from humans and believed that he had a strong bond with the predators to a point of pacifism towards them. His pacifism towards them led to the deaths of him and his girlfriend when he refused to set up security measures in his camp, allowing an aggressive grizzly to enter it and kill them.

* It's revealed in ''Literature/{{Animorphs}}'' that a case of this is what turned the Yeerks into the {{Galactic Conqueror}}s they are. On an expedition to the Yeerk homeworld, the Andalite Prince Seerow felt sorry for the Yeerks, who were fully sentient, but limited by the need for their hosts and Kandrona rays. Thus, he gave them access to Andalite technology and taught them writing, science, astronomy, and even how to build their own portable Kandrona generators. The Yeerks thanked Seerow by betraying him, escaping into space, and enslaving multiple races and civilizations to use as host bodies. It's because of this that the Andalites created a law, aptly titled "Seerow's Kindness," that expressly forbade any Andalite from sharing their technology and secrets with non-Andalites.
* ''Literature/TheDeathGateCycle'' uses this as a subversion of LoveRedeems.
* ''Literature/TheDresdenFiles'' {{discusse|dTrope}}s and {{invoke|dTrope}}s this trope interestingly by proposing that, just like an evil nature simply doesn't go away, you can also count on a ''good'' person to do the right thing even when it's against their best interest. In ''Literature/SummerKnight'' the protagonist gets himself beholden to Queen Mab, the wicked ruler of the Winter Court of the Fae, and they agree to settle his debt by him performing three tasks for her, albeit while retaining the right to veto any one task on principle. After Mab gives him his first assignment and turns to leave, Harry incredulously asks her what makes her believe he will accept it and she tells him the story of the "Fox and Scorpion" and assures him "You will accept this case, wizard. It is what you are. It is your nature." By the end of the book, she's proved completely correct; in the process of fulfilling his task, he discovers a much larger plot, one that any rational person would admit it's ''way'' above his weight class for him to get involved, but Harry -- [[ChronicHeroSyndrome being]] [[SpannerInTheWorks Harry]] -- couldn't help himself but go beyond what he was obligated to do and try to save the day. Just like [[MagnificentBitch Mab]] expected him to.
* The villain Achilles from the ''Literature/EndersShadow'' series has a pathological need to kill anyone who has ever seen him helpless -- including but not limited to a girl who lifted him from low-ranking thug to leader of a prosperous gang, a nun who got him off the streets entirely and enrolled him in a good school, and a doctor who dared use anesthesia to help fix his bad leg.
* An interesting inversion takes place in ''Literature/TheExecutioner''. OneManArmy Mack Bolan sets off on a RoaringRampageOfRevenge when his family dies in a murder/suicide indirectly caused by [[AllDevouringBlackHoleLoanSharks Mafia loan sharks]]. A faction of the New York Mafia Commission, pointing out that their own organisation was created when former enemies made peace, suggest offering Bolan a deal in which he would now work for them. A rival faction is opposed, with one mob boss who's missing several fingers mentioning a pet alligator he tried to raise as an allegory. Although an undercover Fed urges Bolan to take the deal he rejects it, saying he can't let the Mafia even ''think'' that they've won.
* Creator/OrsonScottCard used something similar in his story "The Princess and the Bear", collected in ''Literature/MapsInAMirror''. Having attempted to [[LoveRedeems redeem]] the EvilPrince, the princess [[spoiler:gives up on him and lets the Bear kill him]]. If this sounds like a FamilyUnfriendlyAesop, it ought to be mentioned that the prince and the princess follow the standard cycle of an abusive relationship.
* If any lesson is to be taken from ''Literature/{{Otherland}}'', it's this: never date anyone whose last name is [[NamesToRunAwayFromReallyFast Dread]]. And who likes to be addressed as "[[KingArthur More Dread]]." And whose idea of romancing you is setting a priest on fire for your amusement ...
* ''Literature/LesMiserables'':
** Jean Valjean is taken in by the priest when no one else will after being paroled following nineteen terrible years in prison. Valjean assaults the priest and steals his silver in the night, but while escaping, he is caught by the police as a suspicious character. The priest tells the police that he gave Valjean the silver, and lets him go. This second act of kindness actually ''changes'' Valjean's nature, as he strives to be good in return for this following act of compassion. It's shown that [[HadToComeToPrisonToBeACrook being put in prison had thoroughly corrupted him in the first place]]. His crime was stealing bread to feed his sister's children, for which he got five years, with the sentence extended for every time he escaped.
** This trope is ultimately the reason Javert chooses to commit suicide. Valjean is a wanted criminal, so legally the only thing to do would be arrest him (something which Valjean has promised, by that point, not to fight). Thing is, Valjean also just saved Javert's life at the barricades, so Javert cannot, in good conscience, betray him like that. The only solution Javer can think of is to remove himself from the problem by killing himself.
* Aristophanes quotes Aeschylus in ''The Frogs'' as saying: "Best not to rear a lion's cub in the City, but if you do, its ways must then be served."
* ''{{Literature/Redwall}}'':
** Veil Sixclaw repaid the Abbeydwellers for saving him by attempting to poison one of them. Then again, they may have saved his life but even before he attempted to kill them they always treated him as if he was going to anyway. His foster-mother Bryony, the only one who trusted him, considered this as a FreudianExcuse, but it didn't help. Worse yet, even at the end of the book [[spoiler:and his life]], he himself feels like he is evil or just born bad, even though he [[HeroicSacrifice saved Bryony, sacrificing himself to do that]]. It's also notable for being one of the few books where Redwallians are portrayed in a less-than-sterling light. They're good in themselves here, but their actions toward Veil are ambiguous at best, just as he is ambiguously good or evil. Bryony also seems very uncertain about him even afterward, and both seem to think she should have let him go long before.
** This trope also applies to Chickenhound of ''Redwall'', who is kindly taken in by the Abbeydwellers after they find him lying muddy, bloody, and unconscious in the middle of the road. He repays the gesture by stealing a bunch of random trinkets and [[spoiler:killing Methuselah]], although in his defense the latter was mostly an accident. About the only thing he ''does'' do that's him being nice to the Redwallers is tell them about [[spoiler:Cluny's plans to tunnel into the Abbey]], which turns out to be incredibly useful, but wasn't [[ItsPersonal entirely altruistic on his part]].
** Any vermin Redwallers ever take in or help fit this trope. ''Salamandastron'' has Dingeye and Thura, who eventually [[spoiler:kill Brother Hal]] and then flee the Abbey, stealing [[SpiritAdvisor Martin the Warrior's]] sword and infecting the place with Dry Ditch Fever in the process. [[spoiler:Hal's death]] was accidental and the Dry Ditch Fever was inadvertent, but the sword stealing was their decision, albeit while in a state of panic. The ''Bellmaker'' has the Redwallers take in two wandering corsairs, a captain and his MinionWithAnFInEvil. The captain ends up [[spoiler:killing Mother Mellus]] and stealing a trophy cup, but the trope is inverted when the minion ends up [[spoiler:[[TheDogBitesBack killing ''him'']] and returning the cup to the Redwallers, whereupon he becomes a good friend of theirs and is allowed back to the Abbey for visits.]]
* ''Literature/TheRegenerationTrilogy'': In ''The Eye In The Door'', the "viper" character tells this fable to the "farmer" character in order to explain his actions.
* In ''Literature/TheRiftwarCycle'', [[TheHero Tal]] asks [[TricksterMentor Nakor]] how he can swear an oath to serve the evil Duke Kaspar, who wiped out his people, as part of a ploy by the good guys to spy on him. Nakor tells him the "scorpion and the frog" version of the story and explains that he won't have to break his oath to Kaspar, because it's in Kaspar's nature to betray him first, which would render Tal's oath void. [[spoiler:Sure enough, Kaspar turns on Tal and sends him to rot in TheAlcatraz, leaving him free to enact his revenge.]]
* In ''Literature/WutheringHeights'' Nelly Dean comes close to invoking this when she says that Heathcliff was "harbored by a good man to his bane," implying that Mr. Earnshaw inadvertently ruined his family by taking pity on a homeless orphan.
* In the ''Literature/GuardiansOfGaHoole'' series, Simon saves Kludd from a death by drowning/[[ItMakesSenseInContext having his face melt]], only for Kludd to [[spoiler:kill him as soon as he's well enough to leave]].
* Invoked and eventually subverted in ''TabletopGame/BattleTech'''s Blood of Kerensky novels. Anastasius Focht, the commander of ComStar's military mentions a variation of the fable to the Primus, suspecting her of trying to politicize his upcoming battle with the Clans and attempting to warn her that her penchant for doubledealing could defeat the treaty he was negotiating with them. [[VillainBall She promptly plans to betray the Clans and the Inner Sphere at the same time,]] even calling the operation Scorpion, but the plan fails due to a Mole in the First Circuit, and is assassinated for her betrayal.
* Referenced in ''Literature/MaraDaughterOfTheNile". "I plucked a lily from the gutter and it has turned into a viper in my hands." From Sheftu's perspective, he aided a fugitive slave girl and gave her a purpose and a future (and also fell in love with her)--only for her to turn around and betray him to the Queen. (Mara's side of the story is a little different).
* Given an interesting twist in a chapter header in ''Literature/AgathaHAndTheClockworkPrincess'' - [[spoiler:Baron Wulfenbach was wearing armor under his coat, and announced that the snake construct that was trying to change its nature and didn't bite him would be permitted to live]].
* The Series/DoctorWho book ''Autumn Mist'', set during the Second World War, has one at the end. Garcia, a young medic who has assisted the Doctor throughout the adventure, decides to treat injured soldiers on both sides because he just wants to save lives. [[spoiler:The first German he treats uses his dying strength to stab him with his bayonet, killing him.]]
* In the second book in ''Literature/TheWolfChronicles'', Kaala has a chance to kill [=DavRian=], the human who's been nothing but trouble and a danger to the wolves for the whole book: he'd fallen down a hill and gotten pinned by debris on the edge of a cliff, and all Kaala would need to do is push him and MakeItLookLikeAnAccident. When the opportunity is offered, she refuses because it would go against the Promise and it's just wrong. He repays her by [[spoiler:killing [=TaLi=]'s grandmother and framing the wolves for it]].
* In Literature/TheVampireChronicles, Claudia hunts by posing as a lost waif, then draining any [[GoodSamaritan good Samaritan]] who tries to help her. Lestat also plays the viper in ''The Tale of the Body Thief'' when, while trapped in the body of an impoverished human, he rapes a waitress who feeds him.
* Discussed in the novel ''Literature/{{Hannibal}}''. Barney, Hannibal Lecter's primary handler during his incarceration at the asylum, defies any notion that he fraternized with Lecter. According to Barney, Lecter is ''nobody's'' friend. Lecter was civil with Barney, genuinely thanked him for treating him decently and sent him a generous tip after his escape. Despite that, Barney had no delusions regarding Lecter's nature--at the end of the book, when he spots Lecter and [[spoiler: Starling]] at the Teatro Colon in Buenos Aires, he hauls ass out of town ''that very same night'', knowing full well that Lecter wouldn't hesitate to kill him in order to ensure his freedom. Jack Crawford gives Clarice Starling a similar warning after Lecter's escape. In the end Clarice decides to rescue Lecter from being tortured to death and in return Lecter [[spoiler:brainwashes her with hypnosis and drugs in an attempt to reprogram her with the personality of his dead sister. Clarice is able to resist total LossOfIdentity but still ends up with memories removed and a radical change in personality.]]
* ''Literature/ASongOfIceAndFire''.
** A young Catelyn Tully saved her friend and admirer Paetyr Baelish from being killed by Brandon Stark in a duel for her hand. Years later he would repay her betraying her husband Ned Stark and cause his death as well as her own. It is however implied her plea for Paetyr's life came off as belittling to his character.
** House Hollard was all but wiped out by The Mad King had it not been for Ser Barristan Selmy's plea to spare a young Dontos. Years later Dontos would help Sansa Stark escape to The Vale, only to be killed by Paetyr Baelish who said he was going to sell her out to the Lannisters once the money to pay him off had been spent.
** The Tyrells had been opponents of The Baratheons during Robert's Rebellion but bent the knee when The Targaryens fell. They weren't punished (but they weren't allowed at court) and Renly was even fostered at Highgarden. They repaid the Baratheons by corrupting Renly into trying to take the throne, leading to his death. They then allied with the Lannisters to defeat Stannis Baratheon at Blackwater Bay.
* In Esprit de Corpse 5.13 in ''Literature/{{Twig}}'' a soldier [[WouldNotHurtAChild takes pity on the Lambs]] (Sy, Mary, and Gordon) and doesn't kill them when he has the chance and instead takes them to a doctor to be healed despite likely having direct orders to do so. How do the Lambs reward such kindness? The moment Sy's confirmed okay the Lambs murder him, the doctor, and another soldier in the room before making a break for it.
* ''Literature/WarriorCats'': [=ThunderClan=] decides to be compassionate to Brokenstar on account of his becoming blind and being the son of their medicine cat by taking him in as an elder, despite the fact that he's a murderous and insane cat who tried to raid their camp several times and caused the deaths of quite a few of their number. He thanks the Clan by conspiring with Tigerclaw to kill their leader Bluestar (which fails), after which his mother decides he's irredeemable and kills him herself.
* In ''Ava [=XOX=]'', a children's book targeted towards middle-grade audiences, the main character Ava often reads Aesop's fables and is disturbed by this one, noting that its moral, which seems to be that "no good deed goes unpunished," is actually the opposite of another Aesop's fable, ''The Lion and the Mouse''.

[[folder:Live Action TV]]
* Anyone who talks to Sylar on ''Series/{{Heroes}}.'' Ever. With the caveat that most of the people that try to work with Sylar are decidedly evil themselves. So, it's basically a case of the Scorpion and the Viper.
* ''Series/{{Angel}}'': In the season 3 episode "Offspring," Angel's sire/ex-lover Darla shows up at the hotel, [[MonsterIsAMommy visibly pregnant]]. Seeing Darla's pain over her pregnancy, Cordelia throws Angel out of her room and tries to comfort her, to which Darla responds by [[HandGagging covering Cordelia's mouth]] so she can't scream and biting her neck. Cordelia is only saved by Angel making a ConvenientlyTimedAttackFromBehind. After Darla's escape, Cordelia apologizes to Angel, remarking that she let Darla's condition cloud her better judgment and forgot that pregnant or not, Darla is ''still'' a dangerous vampire.
* ''Series/{{Firefly}}'': In the pilot episode, after he accidentally shoots Kaylee, Lawrence Dobson is protected from Mal and Jayne's retribution by [[BadassPreacher Shepherd Book]]. When Dobson makes his escape, the very first thing he does is attack Shepherd Book and beat him unconscious in a fit of rage.
* ''Franchise/StarTrek'': In the two-part ''Series/StarTrekVoyager'' episode "[[Recap/StarTrekVoyagerS3E25S4E1Scorpion Scorpion]]", Captain Janeway plans a temporary alliance with the Borg in order to combat Species 8472. When she asks for Chakotay's personal opinion, he relates the parable of "The Scorpion and The Frog" mentioned in the page quotes, though with a fox in place of the frog. Oddly, the story as told is more tragic than the normal telling, with the scorpion [[TragicVillain apologizing for being unable to help its nature]], when the Borg would have no such compunctions.
* In the ''Series/StarTrekTheNextGeneration'' episode "[[Recap/StarTrekTheNextGenerationS3E13DejaQ Deja Q]]", Q actually uses this ''against'' the crew when he's turned mortal by the continuum, choosing a human form and going to them for help, assuming that their values and willingness to forgive "almost any offense" will mean they are willing to protect him from the variety of less-moral creatures he has tormented in the past, and who are willing to take advantage of his newfound humanity. [[SubvertedTrope He's not entirely right in this assumption]], but right enough for subverting this trope in "Viper part" too, when [[spoiler:Data's sacrifice moved Q into an attempt to save the ship at the cost of his own life]].
* Two episodes of ''Series/{{Highlander}}: The Series'' featured an 800-year-old immortal named Kenneth, who is trapped in the body of a 10-year-old boy (Immortals stop aging whenever they are "killed" for the first time). Kenneth's standard procedure is to pretend to be a helpless immortal child who only recently found out he was immortal, and when he's taken in he waits for an opportune time and kills his protector from behind, stealing their power.
* On ''Series/TheLateShowWithStephenColbert'' a [[https://youtu.be/LSevfwWBAdA snake]] decries the stereotype of the dangerous viper (only a small percentage of snakes are deadly to humans) and laments he has yet to find a woman that is as affectionate towards snakes as the one in the poem being read on stage.
-->'''Snake:''' Where are all these ladies that love to kiss snakes? I have not found '''one!'''
* In an episode of ''Series/MacGyver1985'', the female antagonist is hanging from a ledge. [=MacGyver=] is all TakeMyHand, but the woman stabs him, causing him to drop her to her death. Pete tells [=MacGyver=] the tale of "The Scorpion and The Frog" to calm him when he questions why she would do that.
* [[InvokedTrope Invoked]] in the Chinese TV adaptation of ''Manga/ThePrinceOfTennis'', where Hai Tang (whose nickname on the court is "Viper") recounts this story as the reason why his teammates shouldn't get too friendly with Long Ma.
* In ''Series/{{Being Human|UK}}'', after [[spoiler: the [[BackFromTheDead resurrected]], amnesiac villain Herrick gets his memories back, he considers killing Nina as revenge on George for killing him, then he changes his mind as she was the only one of the main characters who showed him any kindness while he was in their care. Just when it looks like this trope is going to be subverted however, he decides "But then everyone would think I was going soft" and stabs her. [[MoralEventHorizon She's pregnant, by the way]].]]
* ''Series/TheBill''. An elderly bank robber is caught in the act, and when asked why he'd risk the long prison sentence at his age relates the story. The episode ends with him saying "I'm a scorpion." (i.e. It's my nature).
* ''Series/{{Supernatural}}'':
** In the "[[Recap/SupernaturalS01E01Pilot Pilot]]" episode, a ghost is killing men who see her hitchhiking and pick her up. The trope is averted because her victims have an ulterior motive--she is smoking hot and the drivers are hoping the pickup turns into a hookup and she seeks them to out to punish them for trying to [[YourCheatingHeart cheat on their significant others.]]
** Later in the season, Meg, a frequent hitchhiker who it turns out is a victim of DemonicPossession, is shown killing men who pick her up and [[BloodMagic using their blood]] to communicate with other demons.
** Eve uses a similar technique in Season 6 with a nice and very unfortunate truck driver.
* In the ''Series/NorthernExposure'' episode "Gotta Sing", [[http://www.youtube.com/watch?v=lNC4pm5cnaQ Shelly performs a jazzy version of Al Wilson's "The Snake"]] while warning Maggie that [[CaptainObvious you cannot and]] ''[[CaptainObvious should not]]'' [[CaptainObvious expect unpleasant, mean people to not be unpleasant and mean]].
* LifetimeMovieOfTheWeek ''Bad to the Bone'' is an adolescent version of all those FilmNoir capers featuring a (mostly) good man and an evil woman. A teenage girl [[BlackWidow wants her rich boyfriend dead so that she can get all his money]], so she [[WoundedGazelleGambit lies to her brother that the boyfriend is abusing her]]. The brother shoots the boyfriend dead in an alley, and soon afterward both brother and sister are arrested on suspicion of the murder. The brother makes clear early on that he is willing to take all the blame for the murder in order to save his sister from life imprisonment, or possibly even execution. The sister repays him by [[ScrewThisImOuttaHere making bail and disappearing two weeks before the trial even begins]], leaving her brother to stew in his jail cell while she's living the high life with various other gullible boy-toys. (Even then, [[StupidGood the brother refuses to testify against his sister at his trial]], and it takes him until almost the end of the movie before he realizes what a patsy he's been.) At one point we see the bad girl telling her "life story" to one of the rich male companions she's snagged (she's concocted a MultipleChoicePast to go with the false identity she's assumed), and she says that she had a brother once, but he died!
* In the backstory of ''Series/PowerRangersTimeForce'', BigBad Ransik was rescued and given life-saving medical attention by Dr. Ferricks. He responds to this kindness by setting the doctor's lab on fire and leaving him to die. This makes things rather awkward for the series' later attempts to sell him as a Magneto-esque AntiVillain
* An episode of ''Series/{{Scrubs}}'' has J.D. pull a splinter from the Janitor's toe, and even bring up the parallel to AndroclesLion (with the Janitor saying the story ends with the lion killing and eating the mouse anyway). The Janitor makes a show of offering unwanted payback, and finishes off by pointing out that J.D. could have just asked for him to stop messing with him (and steals his stethoscope when he tries to).
* On ''Series/LazyTown'', oftentimes when Sportacus rescues Robbie Rotten, Robbie's next act is to try to do something else to screw over Sportacus.
* The scorpion variant was referenced by Kevin when dealing with a lawyer who was being particularly feisty on ''[[Series/DragonsDen Shark Tank]]''.
* ''Series/GameOfThrones'':
** Played with Xaro Xhoan Daxos. Daxos was taken in by the city state of Qarth (which is usually closed to outsiders), and proceeds to work his way up to a position of leadership- at which point he has the other leaders killed and declares himself king. However, Daxos attributes his treachery to his love of Qarth- he agrees with the slain leaders that it is a great city, but feels that it will grow stagnant if allowed to continue to be isolated from the rest of the world under their leadership.
** Played straight in "[[Recap/GameOfThronesS4E3BreakerOfChains Breaker of Chains]]". [[BadassAndChildDuo Arya and the Hound]] are given food and shelter by a [[SimilarSquad kindly farmer and his daughter]], who tells the Hound that he has silver to pay him to stay as a laborer and protector should he choose. Instead the Hound robs the man the next day. When a furious Arya calls him out on this, he replies that kindly weak folk like them [[TheSocialDarwinist won't survive the winter, so there's no point in letting them keep the money when he can use it]]. [[spoiler:In a nice DramaticIrony, the Hound is later seriously injured and is robbed of the silver by Arya.]]
** After quelling the rebellion of Ellaria and the Sand Snakes, Prince Doran Martell gives them a second chance, which they promptly use to kill Myrcella Baratheon, Prince Trystane's fiancée. And then they turn on him too.
** Unlike in the books, Cat becomes aware of Paetyr's involvement in Ned's death and wishes she had let Brandon kill him years ago.
* The Daleks in ''Series/DoctorWho''. If someone holds a Dalek's life in their hands, the Dalek will '''always''' beg for mercy. As soon as you give them the chance though, they'll exterminate you without a second thought.
* In episode of ''Series/TheGeorgeLopezShow,'' George finds himself desperately wanting praise from his particularly ungrateful mother, Benny. When his wife Angie suggests renovating her run-down bathroom might get him that elusive "thank you," he throws himself into it full-force, fixing up her bathroom until it's showroom-new. Benny walks into the room, looks around, and... tells George the hook on the back of the door for her robe is too high. Later, when Angie is telling George not to be mad at her, he says he's not, saying you can't be mad at the scorpion for stinging you, it's in their nature. Instead, he's mad at ''Angie,'' who told him to pick up the scorpion in the first place.
* Discussed in the ''Series/MastersOfHorror'' episode "Pick Me Up". Near the end Wheeler (a SerialKiller truck driver) relays to Walker (a SerialKiller hitchhiker) and their mutual victim Stacia the story in the form of a snake and a blonde woman. Walker already knows the punchline because he's heard the "scorpion and the frog" version. The point Wheeler makes is that he knows full well that he picked up another serial killer and expects him to show his true nature. The subversion of course is that he's ''also'' a serial killer, so it would essentially be a scorpion helping another scorpion.
* In one episode of ''Series/GilligansIsland'', a hardened criminal came to the island, and proceeded to kidnap Mrs. Howell, then Ginger, and then Mary Ann, demanding a ransom for their return each time. (This was one of the few times that chest full of cash Mr. Howell had brought proved useful.) When Mary Ann was released, she told the others that he told her he planned to do the same to the other four, and then ''start over again'', so the Professor set a trap for the criminal, and it worked. As the castaways held the criminal in a makeshift cell while the Professor worked on his ship, Ginger felt sorry for him, and asked if she could speak to him, remembering how she once acted in a movie about how a psychiatrist helped a criminal reform. Eventually, the others consented (except the Professor, who had his doubts) and Ginger's amateur therapy seemed to work; for a while, he seemed remorseful and willing to help. Unfortunately, it was an act; at the party they had before they planned to leave, the guy proceeded to steal their jewelry, and then escape on his own. That's when Ginger realized that that's how the movie ended.
* In one episode of ''Series/TwentyFour'', a neighbor helps a character played by ''Kal Penn'' from being attacked by people who target him for his race, unfairly assuming he's a terrorist. Later, it turns out that he actually is, and he kidnaps the neighbor and his family.
* ''Series/{{Firefly}}'' had the moment when Mal spares one of Niska's goons and hands him the money they were paid for the job the didn't do. Instead the guy threatens him so Mal kicks him into a turbine.
* ''Series/OnceUponATime''.
** Snow refused to execute the deposed Regina instead of giving her a SecretTestOfCharacter which she failed. Regina was cursed to never be able to harm anyone in the Enchanted Forest, but Rumpelstilskin manipulates her into casting the Dark Curse.
** Snow's father Leopold set free a genie (Sydney). The genie's love for Regina would later cause him to kill Leopold.
* On ''Series/{{Gotham}}'', Alfred's army mate Reggie Payne shows up at Wayne Manor on a rainy night. Alfred lets him in and Bruce further extends hospitality. Having him around puts Alfred on edge and before he leaves [[spoiler: he steals files on behalf of the corrupt Wayne Enterprises board and stabs Alfred nearly to death]].
* ''{{Series/Grimm}}'': Monroe is captured by an underground gladiator ring. He pulls a nail out of an angry gladiator, much like [[AndroclesLion the Androcles myth]]. Unfortunately, the gladiator is too far gone to remember anything but pain and violence.
* ''Series/TheWalkingDead'': In "Always Accountable", Daryl is attacked by a small group of survivors, led by a man named Dwight, who tie him up and rob him. He manages to escape and take his things back, only to realize that one of them was diabetic and he had inadvertently stolen her insulin. He goes to return it and finds them being threatened by another group, that they had mistakenly believed Daryl to be part of. Daryl helps fight them off, and eventually offers to let them join the community of survivors he's part of. They rob him again.
* On ''Series/TheWire'', Avon could have spared himself trouble by [[spoiler: killing String for having D'Angelo murdered instead of covering it up for their friendship's sake. String later betrays him to the police.]]
* Alluded to in the ''Series/YoureTheWorst'' episode aptly titled "You Knew It Was a Snake". Paul, having finally [[GrewASpine grown a spine]], calls Lindsay out on being so selfish, immature, petty and an all-around terrible wife, to which Lindsay can only sadly but simply retort [[TitleDrop "You knew it was a snake when you picked it up"]], pointing out that Paul let his shallow attraction to her blind him to her many glaring flaws and the fact that she just simply was not "wife material" and he has no one to blame but himself for his own misery.
* In an episode of ''Series/MyNameIsEarl'' where Earl and Randy go back to their old high school to get their [=GEDs=], they encounter some of their old teachers who have become [[ApatheticTeacher resentful of their jobs]] because of [[TeensAreMonsters three students who go out of their way to make their lives a living hell.]] The teachers make Earl a deal: if he can convince them to stop their pranking, they will give him and Randy a refresher course so they can get their [=GEDs=]. The kids of course behave horribly towards Earl and Randy, but then the girl of the trio asks Earl for help on an assignment, Earl happily stays with her after class to help. When he leaves the school he learns that it was just ruse to give her two friends a chance to vandalize Earl's car.
* ''Series/CreepedOut'' has an episode in which two boys befriend an alien who has crash-landed on earth, and try to help him return home; only to find he was actually sent there as a scout for an invasion. The alien points out that he never claimed to be a harmless kid (they just assumed he was), and the closing narration implies the boys should have known better than to blindly trust him.
* ''Series/StargateSG1'' season 8: [[FanNickname Replicarter]] approaches the SGC and Carter in particular with a sob story about how poorly Fifth is treating her and asks for their help in stopping him, but warns that he's developed an immunity to the Disruptor and offers to help them overcome that immunity. They were rightfully wary, but in the end Carter couldn't help but aid her Replicator clone. [[spoiler: There never was a Disruptor immunity, the whole thing was a ploy to study the Disruptor in order to develop one. With the immunity in hand Replicarter [[TheStarscream lured Fifth into range of the Alpha Site where he was killed by a Disruptor Satellite so that she could take sole control of all Replicators]], which she would subsequently make immune to the only real threat.]]
* In the ''Series/TheGoldenGirls'' episode "Brother, Can You Spare That Jacket?", the girls go to a homeless shelter to find a jacket with a winning lottery ticket in the pocket. Blanche catches a young man staring at her purse and snaps at him. He claims he just wanted some gum. She apologizes and they end up having a nice chat, but at the end of the conversation, he warns her to keep an eye on her purse--"I didn't want any gum", revealing that despite having grown to like her, he might very well still steal from her.

* Given a PerspectiveFlip in Nick Cave's song "Fable of the Brown Ape", where the snake is portrayed as a victim rather than a threat.
* Al Wilson's "The Snake" is a variation of the trope-naming story set to music. A "tender-hearted woman" finds a "poor half-frozen snake", and takes it home with her and warms it up, but is bitten in much the manner of the farmer.
-->''"I saved you," cried the woman, "and you bit me, but why?''\\
''You know your bite is poisonous and now I'm gonna die."''\\
''"Oh, shut up, silly woman," said the reptile with a grin,''\\
''"You knew damn well I was a snake before you took me in." ''
* Music/{{Megadeth}}'s song "The Scorpion" alludes to "The Frog and the Scorpion" in the refrain. The lyrics are otherwise more about a figurative scorpion rather than a literal one.
* The song [[http://www.youtube.com/watch?v=D84cuIPx5aQ "The Snake"]] by Mediaeval Baebes is sung in Old Spanish and matches this trope almost completely with the difference being that the snake starts growing dangerously big and when the farmer tries to kick it out of his house, it squeezes him to death instead of stinging him. The lyrics apparently come from a fable from El Libro de Buen Amor (The Good Book of Love) by Juan Ruiz, Archpriest of Hita from the 14th century AD/CE.
* In ASP's "Die kleine Ballade vom schwarzen Schmetterling", the Black Butterfly twice says "Kann nichts dafür, ich bin doch nur ein wildes Tier" (It's not my fault, I'm just a wild animal) in order to excuse torturing (and maybe killing) the protagonist.

* ''[[https://en.wikipedia.org/wiki/The_Scorpion_and_the_Frog The Scorpion and the Frog]]'', an ancient African & European fable commonly [[InTheOriginalKlingon misattributed to Aesop]] is equally [[http://en.wikipedia.org/wiki/The_Scorpion_and_the_Frog#Use_in_pop_culture if not more popular]] than the trope namer, but also deals in how evil is ultimately [[BeingEvilSucks unconsciously self-destructive]]. Sometimes the moral is the slightly more digestible.
--> '''[-Scorpion:-]''' ''[[TakingYouWithMe "Better we both should die than my enemy should live."]]''
* A variation involves the Lion and the Unicorn. The two were enemies, but the Unicorn agreed to let the Lion borrow its horn. The Lion then ambushed the Unicorn and stabbed it with the horn. When the Unicorn asked why the Lion did this, the Lion responded by asking why the Unicorn trusted its worst enemy in the first place.
** The Lion and the Unicorn are respectively the heraldic supporters for England and Scotland, by the by. It's probably best not to elaborate on this point.
* The story of ''[[http://en.wikipedia.org/wiki/Yallery_Brown Yallery Brown]]''.
* A version of the story from the American South comes from the collection that became ''Film/SongOfTheSouth''. In it, Brer Possum helps Brer Snake out of one jam after another, only to be told at the last, "Well, you knowed I was a snake when you put me in your pocket!"
* A [[http://truecenterpublishing.com/zenstory/onesnature.html Zen parable]] tells of two monks who were washing their bowls at a river. One monk saw a drowning scorpion, and saved it, only to be stung -- again and again. The other monk asks why his brother keeps saving a creature whose nature is to harm, and the first monk replies that his nature is to help.
* In addition to the TropeNamer, Creator/{{Aesop}} also told a fable in which a wolf starts hanging around a shepherd's flock but doesn't seem to be causing any trouble and in fact helps manage the flock. The shepherd then makes the mistake of leaving the flock in the wolf's care, and you can guess how that works out. This is where we get the phrase "once a wolf, always a wolf."
* In India there is the story of "The Tiger and the Farmer." The gist is that a farmer was traveling on a road, when he saw a tiger in a cage, the tiger promised that if the farmer opened the cage, he would flee into the jungle. The farmer was suspicious, but let the tiger go, only for the tiger to try and eat the farmer, [[ILied who blamed the predicament on the farmer for trusting a hungry predator.]] Just then a wise man came upon the scene, and asked what happened, when they told him what happened, the wise man asked if the tiger was to big too fit in the cage, the tiger got inside to prove he could fit, the wise man locked the cage and he and the farmer left the tiger locked in his cage.

[[folder:Professional Wrestling]]
* Happens again and again whenever the heel is a DirtyCoward. You can bet [[HoldYourHippogriffs farthings to fritters]] that as soon as the face has overpowered the heel, he'll be on his knees crying: [[BigNo "Nooo! Noooooo!"]] Any face who is not savvy enough to just hit the guy anyway after that will be deservedly punished with a thumb to the eye or an even more painful indignity. (If Wrestling/RicFlair is the heel, the odds of this ''not'' happening are nil.)
* [[Wrestling/JakeRoberts Jake The Snake]] once referenced the aesop in a story as well, demonstrating that the concept has been in the ring for decades. However, in his version, the man asked the snake why he betrayed him as he lay dying, and the snake spoke "Oh, come on. You knew I was a snake the day you found me."
* A rare example of a {{Heel}} doing this to another {{Heel}}:
** During the build to ''Wrestling/{{ECW}} Barely Legal,'' April 13, 1997, a masked man who was [[PaperThinDisguise believed to be]] Wrestling/RickRude was threatening [[Wrestling/ShaneDouglas "The Franchise" Shane Douglas]] and promised to unmask if Douglas successfully defended his [[http://www.wrestling-titles.com/us/ecw/ecw-tv.html ECW World Television Championship]] against Pitbull #2 (w/Pitbull #1) at the [=PPV=]. Douglas won his match, and what was believed to be Rude's voice came over the sound system, saying that he'd take his mask off, but Douglas has to "give up the girl" (Wrestling/{{Francine}}) or he'd give Douglas "the ass-kicking of a lifetime." The masked man then walked out in Rude's trademark robe. Shane pushed Francine toward him. The masked man kissed Francine, who, believing it was [[MrFanservice Rude]], appeared to pass out in delight. Then, one of Douglas' riot guards took off his helmet, revealing ''himself'' to be Rick Rude. The masked man unmasked and took off his robe, revealing, instead, Douglas' Triple Threat ally "Bulldozer" Brian Lee, who then chokeslammed Douglas. Douglas, Wrestling/ChrisCandido and a clearly disgusted Francine ran off, vowing revenge.
** After a few more months of making trouble for Douglas for his own amusement (including pulling up Francine's dress to reveal her panties during Douglas' match with Chris Chetti at ''Buffalo Invasion'' on May 17th), he surprisingly turned on Wrestling/TommyDreamer and [[Wrestling/JimFullington the Sandman]] in a six-man-tag against Wrestling/RobVanDam, Wrestling/{{Sabu}} and Wrestling/JerryLawler at ''[=Heatwave=]'' on July 19th, giving the Triple Threat handsign. Douglas defeated [[http://www.wrestling-titles.com/us/ecw/ecw-h.html ECW World Heavyweight Champion]] Wrestling/{{Sabu}} and Wrestling/TerryFunk in a [[MeleeATrois three-way-dance]] to win the title at ECW's second [=PPV=], ''Hardcore Heaven,'' on August 17th. This led to Rude becoming a manager for the Triple Threat (now, Douglas, Candido and Wrestling/BamBamBigelow, w/Francine) and handpicking opponents for him, as thanks for Douglas giving Rude one night with Francine. Douglas defeated Wrestling/AlSnow, Wrestling/BallsMahoney and Phil [=LaFon=]. Then came the October 16th show at the Elk's Lodge in Queens, NY. Rude told Douglas that he had found him an opponent who "ran roughshod over the [[Wrestling/{{WWE}} WWF.]]" Douglas asked, "You got me [[Wrestling/ShawnMichaels the Boy Toy]]?"[[note]]This was during the time when, due to the interpromotional relationship between ECW and Wrestling/{{WWE}}, Rude was going back and forth working with both Douglas and his hated enemy Shawn Michaels, stemming from Douglas' run-ins with [[Wrestling/TheKliq the Clique]] in WWE in 1995 as Dean Douglas.[[/note]] Then, [[Music/GunsNRoses "Welcome to the Jungle"]] started playing, with Douglas doing a great EyeTake, as BAM BAM BIGELOW was revealed to be Douglas' opponent, meaning that Rude had tricked Douglas [[IdiotBall TWICE in SIX MONTHS.]]
* In Wrestling/RingOfHonor, Wrestling/CMPunk started as a heel, [[HeelFaceTurn turned face]], and was receiving massive cheers by the time he won the [[http://www.wrestling-titles.com/us/roh/roh-h.html ROH World Heavyweight Champion]], at which point he made a promo referencing Aesop's story and declared [[FaceHeelTurn "I'm still a snake, you idiots!"]], declaring that he was going to take the title belt with him to Wrestling/{{WWE}}, and signing his WWE contract on the ROH title belt. Of course, as an indie darling and a good performer, he was {{face}} for over a year (and not just with indie fans) since hitting WWE...and then he assaulted fan favorite Wrestling/JeffHardy and stole his title after Jeff had been champion for about five minutes.
** As part of a ContinuityNod, he did basically the same thing in WWE. This time, with a very interesting result.
* Wrestling/{{Edge}} did something similar in 2010. Returning from injury during the Royal Rumble, he came back to a huge ovation as he won the match and went into Wrestlemania as the challenger for the World Heavyweight champion. After coming up short too many times and then getting traded to Raw, Edge revealed his true nature in rant, going on about how switching shows ruined his opportunity to be the top face of Smackdown.

[[folder: Radio]]
* In a 2014 episode of ''Radio/TheNowShow'', John Finnemore updates "The Frog and the Scorpion" as "[[https://www.youtube.com/watch?v=HetLxhI1txY The Business Secretary and the Hedge Fund Managers]]", with the moral that hedge fund managers (who are definitely not scorpions) can't be expected ''not'' to manipulate shares of public services to maximise their profits if they have the opportunity to because that's their ''job'', and it should be the job of the government not to give them the opportunity if doing so would be bad for the country, instead of just trusting they won't. It's also mentioned that the hedge fund managers aren't vindictive, just uncaring; rather than trusting a scorpion not to sting, it's more like trusting a fire not to burn.

[[folder:Tabletop Games]]
* In the game ''TabletopGame/LegendOfTheFiveRings'', the classic story of the frog and the scorpion is told, but when the frog asks the scorpion why he doomed them both:
--> '''Frog''': Now we shall both die! Why on earth did you do that?\\
'''Scorpion''': [[IAmNotLeftHanded Little frog,]] [[ForTheEvulz I can swim]].
** In fact, "I can swim." is literally the family motto of the Bayushi, the primary Scorpion Clan family.
** Specifically, Bayushi smiled after he heard the story, telling Shinsei that he understood the meaning of the story. His eyes revealed that he didn't really have enlightenment. So Shinsei hit him in the mouth. Bayushi then covered his mouth, because it was what had lied. The Scorpion Clan wear masks in memory of the event, and to make it easier to lie. It's hard to believe that a spymaster and the man that taught an Empire to deceive somehow couldn't stop smiling.
* Defied in ''TabletopGame/PrincessTheHopeful'': A [[TheMedic Mender]] Princess' first Oath states they are supposed to heal and help anyone who requests it, regardless of who that person is, but it also points out they are allowed to take precautions to protect themselves and their loved ones should this trope be a possibility. After all, [[GoodIsNotDumb just because you must help everyone doesn't mean you have to be stupid about it]].
* The [[TabletopGame/{{Warhammer40000}} Imperium of Man]] ''loves'' this fable, since their state religion is founded on {{Absolute Xenophob|e}}ia.

[[folder:Video Games]]
* A variation: ''VideoGame/KnightsOfTheOldRepublic'', Jolee Bindo, having lived as a hermit on Kashyyyk for twenty years, helps the player character out and then follows you offworld. For a good while he claims that his reasoning is that he'd finally gotten sick of the planet, he wanted to see the stars again. But as he gets to know you he tells you a parable about a young man who one day finds a snake in his village. He follows the snake, helping it away from the village and into a great desert. Without food or water to be seen, the snake bites the young man. The snake then asked why the man followed him, and the man replies; "Did I follow you? I thought I was leading you away from everyone else!" Considering that the player character is [[spoiler:Darth Revan]], that parable might or might not apply to you. At any rate, this particular snake can choose whether or not to bite.
* In ''VideoGame/AgeOfWonders'' the Keepers attempt to raise some goblins to be good. The Cult of Storms has no trouble convincing the goblins to riot and help kill the Keepers' leader.
* In my ''VideoGame/DragonAgeOrigins'', [[spoiler:Sten]] was left for dead when the darkspawn massacred his squad. When he came to, he found that he had lost his sword (without which he could never go home again) and slaughtered the villagers who picked him up and nursed him back to health in blind rage. He follows the player as his own RedemptionQuest because of this.
* In ''VideoGame/FalloutNewVegas'', the Courier can horribly screw over both of the people involved in saving their life after they were shot in the head and left for dead, first by joining up with the Powder Gangers to destroy Doc Mitchell's hometown of Goodsprings, then by blowing up an army of Victor's securitron "brothers" and murdering his creator, Mr. House. The Courier could also be the victim of this trope in an event that was cut from the game: [[spoiler: If the Courier saves Benny from Caesar (this is after Benny [[TooDumbToLive tried to kill The Courier twice]]) Benny was originally supposed to ambush The Courier afterwards.]]
* In ''VideoGame/BatmanArkhamCity'', Batman saves a Two Face thug from being lowered into a vat of molten steel by Joker Thugs. Once the thug is offscreen (invisible to the player, even if within Batman's line of sight), he attacks Batman.
* ''VideoGame/HeavyRain''. Without spoiling anything, suffice it to say that during the ending showdown with the Origami Killer, it is entirely possible that the fight will end up on a tall structure, and properly dodged or countered attack will leave the killer hanging by his fingertips over a deadly drop. The killer will humbly ask for your aid, and you have the option of pulling him to safety or letting him fall. Should you choose the former, the killer will give you a sincere-sounding word of thanks before immediately resuming his attempts to kill you. Even the most GenreBlind player would see this outcome a mile away, but the killer is so FauxAffablyEvil that most players are tempted to at least take a chance on saving him.
* If you killed the Rachni Queen in the first ''Franchise/MassEffect'', the Reapers create a husk Queen in the third game to produce Ravagers. The Queen is understandably enraged at having been created as a monster to create more monsters, and wants to help fight the Reapers... supposedly. She ends up betraying you, not only taking away the Assets she provided but also decimating your Engineering Corps. If you saved the queen...this trope is averted. Despite your allies warning you that this might be the case, the Rachni Queen fully understands why her race was originally destroyed and vows to aid you in any way she can if you spare her, which she will if you make the right choices in 3.
* In the ''VideoGame/{{Tekken}}'' series, [[NinjaPirateZombieRobot zombie cyborg former Interpol agent]] Bryan Fury is saved by Dr. Boskonovich and installed with a perpetual generator. Bryan's thanks is to trash the lab and kill members of the Manji clan, who were led by Dr. B's close friend Yoshimitsu.
* Likely in any game with multiple factions but a GangUpOnTheHuman mentality. If you run into a battle to save one group it's far more likely that everyone will immediately start ignoring eachother and focus entirely on destroying you.
* This is [[spoiler: Kira's]] ending in ''VideoGame/MortalKombatArmageddon''. [[spoiler:She uses the life energy granted to her by the Elder Gods to bring back Kobra, her old Black Dragon team mate who died in battle, and who was a pretty big JerkAss when he was alive. Kobra repays the favour by killing her, calling her weak and saying that she should have left him dead. The other way around is the same too, in Kobra's ending, he also had the Elder Gods revive Kira, who proceeds to kill him with a kiss of death.]]
* A good chunk of ''VideoGame/TalesOfXillia'' ''relies'' on this trope, so much so that it's barely even a spoiler. Jude forgives Alvin for betraying the party about [[FaceHeelRevolvingDoor four or five times]], despite the fact that one of these times [[spoiler: almost directly causes Milla's death.]] And of course, he just keeps on betraying you, and every time it gets worse. He's not really evil, though - he's just in possession of a DarkAndTroubledPast.
* ''VideoGame/TheElderScrollsVSkyrim'':
** Sometimes when fighting Bandits they'll crouch down and proclaim they yield and beg for their lives. So okay, you spare them... two seconds later they get a second wind and try to kill you again. And no they are not ever scripted to "Yield for good".
** In the ''Dragonborn'' DLC, one of the bosses you have to defeat, Ildari Sarothril, is a mage apprentice who served as a test subject for her master, who abandoned her after thinking she had died in the experiment. When you track her back, you find out she had since been found and nursed back to health by a group of miners. Having turned insane from the experiment, she repayed their kindness by killing most of them out of paranoia, and turning the others into test subjects.
* In ''VideoGame/{{Touhou}}'' there was a man named Iwakasa that saved a young girl while he was on a misson to destroy a dangerous artefact. The girl tagged along him on his misson but after some events on Mount Fuji he was killed by the girl on the descent and she took the artefact for herself. The artefact was the [[ImmortalityInducer Hourai Elixir]] and the girl was Fujiwara no Mokou.
* Part of ''VideoGame/{{Nox}}'''s history includes a warrior named Jandor growing tired of the massive war he was a part of, and eventually refusing to kill a young girl who's the last of the Northern Mages and their "cursed blood legacy", instead handing her over to be cared for by a tribe of ogres. The girl's name: Hecubah, the BigBad of the game who's trying to TakeOverTheWorld.
* This trope is debated in ''VideoGame/BreathOfFire3'' in regards to the Nue. While Bunyan tasks Rei with killing it, Ryu and Teepo catch up and lend a hand, only for the trio to find it clutching a cave behind it in its death throes; looking inside reveals that it had cubs, all of whom are also dead. The resulting debate shows that Bunyan is fully aware of this trope, and expects the Nue cubs to do the same thing all over again next time if they were alive.
-->'''Rei''': Hold on! This thing was attacking the village just so it could feed its cubs... and you had us kill her?!\\
'''Bunyan''': If you knew that it had cubs... would you have let it live?
* In ''VideoGame/{{Undertale}}'', on a No Mercy route, this can be applied to anyone who tries to show you kindness. Perhaps most notable is Toriel, who invites you into your home and treats you with love... only for you to [[spoiler: murder her and all the inhabitants of the Ruins. There was also an example of this in the backstory with Asriel and the Fallen Child. How much of it was genuine malice is ambiguous, but they tried to convince Asriel to murder humans and restart the war against humanity despite having (apparently) found happiness as Toriel and Asgore's adopted child, the end result being the death of both of them.]]
* ''VideoGame/RatchetAndClankFutureToolsOfDestruction'': Upon discovering his heritage as a [[AlwaysChaoticEvil Cragmite]], [[BigBad Emperor Tachyon]] immediately got to work on [[FinalSolution wiping out the entire Lombax race]] (the ones who ''raised him from a hatchling'', in spite of what he was) and coercing the Drophyds into helping him take over the galaxy and bring about the return of said Cragmites. Ratchet rightfully [[LampshadeHanging calls him on it]]:
-->'''Ratchet''': The Lombaxes ''raised'' you! How could you do this to them?
* In ''VideoGame/FableI'', the FallenHero and bandit leader Twinblade begs the Hero of Oakvale for his life if defeated in combat, and sends a squad of assassins after the Hero if shown mercy.

* In ''Webcomic/{{Drowtales}}'', Ven'nedia accepts the ''highly'' [[DemonicPossession demon tainted]] CreepyChild Kharla'ggen into their "clan" (at that point more a group of tainted drow seeking mutual protection and understanding) to try and help her adapt to her condition and live a normal life. She and her daughter treat her like family, and even normalize her enough that, while still incurable, she settles down. Then their clan is attacked and nearly destroyed, and she ''kills all the invaders singlehandedly''. When rival Sene'kha proposes using Kharla'ggen as a figurehead leader she is opposed, and when voted down tries to run away with her daughter Kiel'ndia ... only to have Kharla'ggen turn her into a living puppet, put on display over their main entrance to scare enemies (and allies).
* ''Webcomic/BobTheAngryFlower'' [[http://www.angryflower.com/scorpi.html tells it as it is]].
* The parable is used as the basis of a weapon's backstory in ''Webcomic/KeychainOfCreation''. This is ''TabletopGame/{{Exalted}}'', even the swords have cool histories and vendettas. And since the Farmer here is called "[[NamesToRunAwayFromReallyFast The King of the Uncloaked Steel]]," it should come as no surprise that [[http://keychain.patternspider.net/archive/koc0087.html he basically finds eventual betrayal to simply be a bonus to their relationship]]. And [[InterspeciesRomance they also fall in love]], with the eventual betrayal still staying the same. They're just weird, crazy people/Exalted/Snake-swords.
* The Scorpion and the Frog parable, above, inspired Vriska Serket in ''Webcomic/{{Homestuck}}'' (or rather, ''she'' inspired ''it''), as her motif is arachnids and has a self-destructively malicious nature. Appropriately enough, she [[spoiler:dies (again) by trusting her worst enemy, Terezi, not to kill her when her back is turned. Terezi, having foreseen the consequences, stabs her in the back.]]
* ''Webcomic/{{Freefall}}'' has this happen to Sam in [[http://freefall.purrsia.com/ff400/fv00342.htm this]] strip.
* Subverted in ''Webcomic/BobAndGeorge'', in the ''Mega Man 3'' storyline, everyone is telling Dr. Light he's an idiot for trusting Dr. Wily. As expected, Dr. Wily betrays them and steals Gamma and the power crystals, [[spoiler: only for Gamma to fail as Dr. Light had the power crystals replaced with faulty ones, and Dr. Light saying he wasn't stupid and took precautions.]]
-->'''Dr. Light''': Just because I gave Dr. Wily the benefit of the doubt doesn't mean I didn't have a back-up plan.
* Used as a motif in a [[http://www.sluggy.com/comics/archives/daily/130218 side adventure]] in ''Webcomic/SluggyFreelance.''
* Variant in ''Literature/AgathaHAndTheClockworkPrincess'', a novelization of ''Webcomic/GirlGenius''; EmperorScientist [[TheExtremistWasRight Klaus Wulfenbach]] takes in vipers all the freaking time, as most of his enemies are crazy and/or evil and he wants some vague semblance of peace. He just takes precautions first.
-->One day the Baron was out a-walking, when by the side of the road, he found two injured constructs.\\
They possessed the faces and torsos of beautiful women, and the bodies of deadly serpents.\\
"Help us, kind sir," the creatures begged.\\
"Of course," said the Baron. He took them to his castle, and patiently nursed them back to health.\\
And when they were both once again sleek and strong, the first one bit him with her deadly, poisonous fangs.\\
"Why did you do that?" screamed the second construct. "He helped us!"\\
The first construct shrugged. "He shouldn't be surprised. He knew we were monsters when he took us in."\\
"But we don't have to act like monsters," said the second. "I have chosen not to!"\\
"And that," said the Baron to the second construct as he revealed the armor beneath his clothing and drew forth his terrible sword, "Is why you will live."
* The frog-and-scorpion version shows up in-story in ''Webcomic/{{Sinfest}}'', found in a book by [[HeelFaceTurn Fuchsia]], who [[http://www.sinfest.net/view.php?date=2015-08-04 doesn't like it]]. Fortunately, [[ChasteHero Criminy]] [[http://www.sinfest.net/view.php?date=2015-08-11 refutes it.]]
* Another frog-and-scorpion version shows up in a Sunday special of ''Webcomic/KevinAndKell'' where the scorpion subverts the tale and lampshades by saying the [[http://kevinandkell.com/2018/kk0610.html story doesn't take into account ethics, moral compasses and free will]] firmly fitting the scorpion on the [[NurtureOverNature nurture]] side of the NatureVersusNurture debate.

* In ''Literature/{{Twig}}'', Sylvester, a ChildSoldier HumanWeapon created by an AcademyOfEvil which is fighting against a rebellion, is trapped by advancing elite rebellion troops who use a new [[AgonyBeam agony inducing bullet]] to drive Academy warbeasts mad with pain. Sylvester is captured, but spared due to an enemy soldier seeing him as a child in pain, and is taken to a medical tent, where he and his companions receive treatment, but they promptly kill the medic and the soldier before going on to attack the rebellion forces from the rear using their own incendiaries.

* ''WesternAnimation/AvatarTheLastAirbender.'' While Aang, ''Sifu'' ThouShaltNotKill, consistently saves [[{{Determinator}} Zuko]], Sokka, who's spent his whole life in a ''war'', asks why they should help him in the first season finale, given that all the previous times they've saved him or shown mercy he's tried to capture Aang. [[spoiler:This is brought to a head when Katara bonds with him over their (supposedly) dead mothers and offers to try healing his [[GoodScarsEvilScars scar]]... only to face him battling alongside his [[CainAndAbel sister]] in a battle that temporarily [[OurHeroIsDead cost Aang his life]].]]
** In the third season [[spoiler:Aang was ultimately proven right, though - he needed a firebending teacher at the exact same time Zuko did his HeelFaceTurn.]]
** [[ArsonMurderAndJaywalking In a less extreme example,]] during Zuko's exile in the Earth Kingdom, a woman and her mother take him and Iroh in for dinner. As they leave, Zuko steals their Ostrich Horse.
** Also, in "Imprisoned", Haru uses his Earthbending to save an old man from a cave-in. Later that night, the old man rats him out to the Fire Nation and gets him arrested.
** In "Zuko Alone", Zuko has a brief stay with a poor farm family after covering for their son and driving off some extortionist Earth Kingdom soldiers. At the end, after the boy is taken hostage by the soldiers (admittedly in part because of a keepsake Zuko gave him), Zuko fights them to save him from conscription. Unfortunately for Zuko, a combination of his firebending in battle and his own [[BadassBoast declaration of his identity]] sees him shunned by everyone in town, even the boy who saw him like a hero not 3 minutes ago.
* In Season 3 of ''WesternAnimation/TheLegendOfKorra'', the heroes meet an orphan named Kai, who claims that his parents were killed fighting a gang of bandits. The law enforcement officers chasing him say that he actually was adopted by a wealthy family, and "thanked" them for their kindness by clearing them out of all their valuables and making a run for it. Kai ultimately proves to be a JerkWithAHeartOfGold following some CharacterDevelopment in later episodes -- he notes he probably deserves the suspicion he received up to the final episode of the season.
* ''WesternAnimation/BatmanTheAnimatedSeries:'' Killer Croc escapes while escorted by train to a prison, Batman in hot pursuit. They fall off a cliff and are knocked out. Croc wakes up in a secluded home owned by former circus performers. It's Croc's perfect chance to start a new life. Naturally Croc claims Batman is evil to get their help in capturing him. Then Croc captures everyone and plans to kill them and run off with their retirement money. When he's eventually foiled, he does seem a little regretful as he's taken away.
--> '''Eddie Deacon/Billy (the seal boy)''': Why Croc? Why'd you turn on us like that? We could've helped you, we could've done something.\\
'''Killer Croc:''' You said you could be yourself out here, remember? [[CryForTheDevil I guess that's what I was doing. Being myself.]]
* ''WesternAnimation/TheSimpsons''
** Lisa makes it her goal to help Burns rebuild his lost fortune in a socially responsible way. He takes to her teachings with zeal, but in his efforts to follow her instructions he creates a recycling plant that strip mines ocean life into an all purpose slurry. It ends with the memorable scene of [[GranolaGirl Lisa]] running house to house begging people ''[[{{Irony}} not]]'' to recycle!
** It then happens again, many seasons down the road, when Burns is brain-damaged and has lost his memory. Most of the Springfieldians take advantage of this to get revenge on him for everything he did to them. Lisa takes pity on him, and ends up restoring him to his former, evil self, with the added lesson that hatred is the only thing keeping him alive.
** An earlier episode had Marge take an interest in reforming Jack Crowley, a prisoner convicted of armed robbery (voiced by Creator/MichaelKeaton) by encouraging his casual interest in art. The warden agrees to let Marge take Jack into her home and help him find a job as a mural painter. When Marge hears that Principal Skinner wants a mural painted for Springfield Elementary, she suggests Jack for the task. But Skinner forces him to paint a [[TastesLikeDiabetes treacly, cutesy scene]] instead of what he actually wanted to paint - and then, to add insult to injury, Skinner has Jack take all the blame when the mural proves unpopular. Jack has to be restrained from physically assaulting the principal, and soon afterward a plot to burn down the school is uncovered. Marge finds Jack hiding in the playground and accuses him of going back to a life of crime; Jack lies that he's innocent, prompting Marge to believe him and to help him escape. Marge's reward for this is seeing Jack pour gasoline on Skinner's car and light ''that'' on fire in full view of everyone, [[LaughingMad laughing diabolically]]. Jack is quickly arrested and finally confesses to indeed starting the school fire, but [[ImplausibleDeniability not the car fire]], leaving Marge disgusted.
** That episode where Homer and Marge lose custody of the kids who are adopted by The Flanders's. They show Rod and Todd an Itchy and Scratchy cartoon where Itchy is adopted by Scratchy only to be killed. The dying Scratchy asked Itchy [[TearJerker "Why?"]]
* The episode "Action Figures" of ''WesternAnimation/SupermanTheAnimatedSeries'' featured a couple of kids sheltering an amnesiac Metallo, who they think is a good robot who can be like Superman. In the beginning, he does do good and helps save the kids and trucker, but as more of his memories return he reverts to his evil persona. In "gratitude" for helping him, he tries to kidnap the kids and leave the volcanic island their parents are researching. When one of the children tries to appeal to goodness, he replies [[ThatManIsDead "Steel Man? Steel Man is dead!]] And so are you Superman!" Lois Lane later consoles the children with "He ''was'' good, when he was with you. Now all the goodness in him is buried, along with the rest of him".
* An episode of ''WesternAnimation/MickeyMouseWorks'' involved Mickey rescuing Pete from the cold and warming him up inside the mouse's cabin. Being the greedy prick he is, Pete reveals he only pretended to be freezing to death as he and his cousin take over Mickey's cabin. Of course, being a cartoon about Disney's beloved mascot, Mickey not only managed to turn the two against each other, but, in the end, tricked the criminal dimwits into turning themselves into the police.
* On ''WesternAnimation/JimmyTwoShoes'', Jimmy agrees to care for a [[WickedWeasel weavil]] he believes to have injured, despite Beezy's warnings that weavils are AlwaysChaoticEvil. Indeed, the weavils take full advantage of him, slowly transforming him into one of them.
* In the [[CanonDiscontinuity oft-disputed]] third season of ''WesternAnimation/{{Gargoyles}}'', a common tactic the villains used was having someone pretend to be in danger in order to lure the heroes into a trap.
* In an episode of ''WesternAnimation/FamilyGuy'', Lois finds out she has a brother (voiced by Creator/RobertDowneyJr) who was put in a sanitarium by her parents after a traumatic event and kept a family secret. Lois, assuming her awful parents were just being awful again, brings her brother home to live with her. It turns out he's a dangerous psychotic who kills fat people. He goes on a killing spree that ends with him trying to kill Peter.
** This was also the point of the episode where Peter befriends OJ Simpson. The Griffins come to the conclusion the OJ is really an O.K. guy who deserves the benefit of the doubt, only for him to stab a woman in plain view of everyone and go running off on a mad killing spree.
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "Griffon the Brush Off," Pinkie Pie declares that she'll have to do something about Rainbow Dash's PoisonousFriend Gilda. We're led to believe this involves provoking Gilda with party pranks until she loses her temper and Rainbow can see how bad she is, but it turns out Rainbow herself set up the pranks and it was only chance that Gilda ran into all of them; Pinkie's plan was simply to throw a party for her in the hopes that it would get her to lighten up. Needless to say, it fails miserably, but at least Rainbow does learn Gilda's true nature and kicks her to the curb. Four seasons later, [[spoiler:it ends up subverted, when Gilda reappears and gets her redemption]].
* ''WesternAnimation/TheSmurfs'' episode "All Creatures Great And Smurf" has the adult Nat Smurf getting his fellow Smurfs to help get Azrael's paw out of a bear trap by bringing him into the village. At first Azrael seems grateful, but upon hearing his master Gargamel calling out for him, he reverts back to his own evil nature and is almost ready to tear Nat Smurf to shreds when he gets chased off into the forest by a larger creature. Nat Smurf mistakes this situation for an AndroclesLion.
* A skit on ''WesternAnimation/RobotChicken'' referenced the famous ''Scorpion and the Frog'' story. The skit lampshades how insanely nonsensical and StupidEvil someone would have to be to act like the scorpion. This time, the Frog catches the scorpion just before it stings him and is ''not'' [[FreakOut happy with him]].
* In one episode of ''WesternAnimation/EvilConCarne'', the title character and Cod Commando are marooned together on an island, and Hector successfully uses this trick on Cod ''three times in the same episode.'' (The fourth time he tries it, when success is vital to escaping, Cod wises up, and leaves him behind.)
* Early on in ''WesternAnimation/XMen'', when Sabretooth winds on at the X-Mansion's doorstep, Professor Xavier takes him in and attempts to help him overcome his bestial urges, with Wolverine being the only objector. It goes about as well as you can expect: when Jubilee attempts to help him out with his hospital restraints so they won't be too uncomfortable, Sabretooth breaks loose and attacks her, forcing Wolvie to fight him off, which also results in him getting injured in the process.
* ''WesternAnimation/AdventureTime'' has the Magic Man, who teaches us all an important lesson about not giving sugar to [[JerkAss jerks]].
* ''WesternAnimation/KungFuPandaLegendsOfAwesomeness'' averts this to some extent in the 'Po Picks A Pocket' episode, wherein Po is initially tricked into being kidnapped by a group of adorable, seemingly-innocent child thieves, even as young as toddlers. During Po's imprisoning, the kids attempt to justify this by explaining that they have no other option besides this, due to being held captive by their thieving leader. Po offers to break them out of their situation, and leads them back to the Jade Palace, where they appear to be settling in just fine...that is until they trick Po ''again'', by imprisoning him in the Palace's dungeon so that the leader thief can steal a precious ruby. It isn't until Po points out they cannot split a single ruby between each other for profit, that the kids turn on their leader once again, now having completed the aversion of the trope.
* In ''WesternAnimation/TotalDrama Total Drama: World Tour'', the show's resident [[ManipulativeBastard backstabbers]], Heather and Alejandro, recognize each other for what they are and agree to [[EnemyMine work together]]. Despite knowing Heather has betrayed everyone else who allied with her (including ''him'' in a previous episode) Alejandro [[LoveMakesYouStupid continues]] to trust her...[[spoiler:a mistake which singlehandedly loses him the game]].
-->'''Heather:''' [[spoiler:Boys are okay, but a million dollars is way better.]]
** In ''WesternAnimation/TotalDramaPresentsTheRidonculousRace'' [=MacArthur=] [[SaveTheVillain saves Josee from drowning.]] Pretty much as soon as they're back on land, Josee trips her up so she and Jacques can get ahead.
* ''WesternAnimation/StevenUniverse''
** In the episode "Message Received", it seems like all Steven's efforts to befriend [[spoiler:Peridot]] and make her see the beauty of Earth were in vain, as it seems she still intends to betray them and contact Yellow Diamond. Garnet tells Steven that some people aren't worthy of being patient with. [[spoiler:[[SubvertedTrope As it turns out]], Peridot does ''not'' betray them, nor did she ever intend to. Her plan ([[PoorCommunicationKills which could have been articulated better]]) was to convince Yellow Diamond of the Earth's value. Unfortunately, Yellow Diamond turns out to not be the person Peridot thought she was. As a result, [[HeelFaceTurn Peridot defects to the Crystal Gems entirely]].]]
** The episode "Bubbled" has Steven floating in space with a Ruby Soldier he calls Eyeball. After her gem gets cracked--which can be fatal--Steven pulls Eyeball into his protective bubble and uses his powers to fix her gem. Using that healing power makes Eyeball realize Steven really ''does'' have Rose Quartz's gem, as he'd been trying to tell her, so Eyeball pulls a knife and tries to carve Steven's gem out so she can be a hero for capturing Rose Quartz.
** In the episode "Room for Ruby", the character [[spoiler: Navy]] crashed in front of Steven's house from space, begging for forgiveness and asking to join the Crystal Gems, claiming the other [[spoiler: Rubies]] were mean to her. Steven and Peridot let her join with no hesistation, while Lapis has suspicions. At the end of the episode, it is revealed that Lapis is right, when [[spoiler: Navy steals her ship and reveals she enjoyed deceiving the Gems because she wanted to see their faces once she revealed her true motives.]]
