{{Love Triangle}}s are tricky business. Trust us, [[TriangRelations we've already done the math]].

It can get particularly twisted when some sides of the triangle are completely one-sided. Bob is in love with Alice, but Alice not only fails to realize it, but is already in a relationship with Chris. This is a classic recipe for drama (or humor), but sometimes, it goes too far.

Sometimes, somehow, Bob gets the idea that Chris is the one [[GreenEyedMonster in the way]] of Bob's happiness with Alice, and if Chris were to somehow have an [[MakeItLookLikeAnAccident "accident"]], then surely Alice would come to love Bob instead. It's true -- LoveMakesYouEvil.

Not always the best thought-out plan, no. Sometimes, Bob may not even consider what would happen if Alice ever found out. If this isn't TheReveal for a {{Yandere}}, it's still her most shocking moment.

(If it is an equilateral triangle, the TenchiSolution occurs.)

Compare OppositesAttractRevenge. Contrast IWantMyBelovedToBeHappy, which may be subverted into this trope, and vice-versa. Contrast [[{{ptitlev7j92pykrb48}} If I Can't Have You]], for when it's the Cathetus that will be murdered. If this is done indirectly by setting the hypotenuse up to be killed, it's either {{Death of the Hypotenuse}} or {{The Uriah Gambit}}, with the latter intentional and the former set up only by the author.

[[folder: Anime and Manga ]]

*This is often the path villains take in SailorMoon. Beryl, En, and Black Lady try to kill Usagi to get Mamoru, while Ali and Demand try to kill Mamoru to get Usagi. Esmeraude Also tries to do in Usagi to win Demand.
* Sae from ''PeachGirl'' hates Misao for being the one Ryo loves since she loves him herself and, at one point, tried to push her into the path of a moving bus. However, Kairi restrained her at the last second so she wasn't able to.
** Maybe not "murder", but Kairi's trio of ClingyJealousGirl's absolutely '''hate''' Momo for winning Kairi's affections. Plus they make a habit out of harassing/threatening her, and, at one point, hold her down, and tell her that she has to sign a contract swearing that she'll stay away from Kairi or they'll burn all her hair off, and try to beat her up later on. (all while holding a lighter to her hair.) In addition, they take the threat even further with "We'll burn your face so badly that no guy will ever look at you again," and "Don't worry, we'll push you into the pool before your whole body catches fire."
* ''PeacemakerKurogane'': In the manga, Suzu comes to this conclusion when Ryoma decides to take Tetsunosuke away from him.
* ''CodeGeass'': [[spoiler: Rolo]] does this to [[spoiler: Shirley, Lelouch's "girlfriend"]], and later plans on doing this to [[spoiler: Nunnally]] to prevent them from coming in between him and Lelouch.
** It must be pointed out, though, that [[spoiler: Shirley]]'s biggest mistake wasn't necessarily [[DieForOurShip being in between]], but actually [[spoiler: mentioning that she ''knew'' Rolo wasn't Lelouch's true brother and that she wanted to reunite him with Nunners]]. Which is somewhat understandable because [[spoiler: Shirley had NO way to know about Rolo's mental and emotional instability]].
** Besides, fans pretty much [[{{Flanderization}} flanderize]] this to absolute death, ''at least'' partially due to fandom homophobia. ThisTroper is ''sure'' that, had either C.C or Kallen killed [[spoiler: Shirley]], they would've been ''cheered on'' by the FanDumb.
*** But only the FanDumb. Most people who disapprove do so because of the coldbloodedness therein.
* Happens a great deal in ''[[RanmaOneHalf Ranma 1/2]]''. Many of the characters have at least once tried get rid of Ranma (and sometimes Akane, in the case of Shampoo) to have a shot at the one they love. Ryoga Hibiki and Tatewaki Kuno are the prime offenders, with Mousse running a close second in the anime and early manga. At least Ryoga [[CharacterDevelopment grew out of it]], and Mousse changed tactics to just "[[TheOnlyOneAllowedToDefeatYou beat up Ranma to prove my superiority]]."
** In the case of Shampoo, the first time, she tried to blame it on ''someone else'' (who had kidnapped Akane to use her as a bait for Ranma). The second, she outright threatened to kill Akane ''to Ranma'', although she was under MindControl and had been ordered to eliminate Ranma at that point.
-->'''Shampoo''': ''(dead serious)'' [[NeverLiveItDown Obstacles are for killing!]]
* In one of Animerica's darkest filler episodes, [[spoiler:[[StalkerWithACrush Kiyone]]'s character does this to Makoto (Janine's LoveInterest at the time) in a ''most'' brutal manner in order to get closer to Janine. However, she quickly finds out his true nature, and while she attempts to escape she discovers [[GoryDiscretionShot Makoto's dead body.]] Cue the [[AndIMustScream reaction]] and much NightmareFuel following what Kiyone [[IHaveYouNowMyPretty plans to do]] [[RapeIsLove with her]] next... If it weren't for Kasuse's BigDamnHeroes moment, things would have been very messy indeed.]]
** Please state which anime and/or manga you're describing.
* Uruka in ''SteelAngelKurumi2'' tries to get rid of Kurumi, since she she takes up all of the attention of the girl she loves. Of course, her plan to use Steel Angel Saki for that purpose [[FailureIsTheOnlyOption totally backfires]].
*On the topic of Kaishaku's works, an interesting case of this occurs in [[KyoshiroToToraNoSora Shattered Angels]] where resident [[PsychoLesbian psycho lesbian]] Mika Ayanokoji tries to sacrifice the hypotenuse. Ultimately it's cut short before anyone's sacrifices, but is ironically turned around when Mika is [[ImpaledWithExtremePrejudice killed off rather nicely]].
* Harry from {{Outlaw Star}} and Kisshu from {{Tokyo Mew Mew}} are both stalkers who constantly attempt to get rid of those who are in the way of their love with the terrified female leads, even the female leads themselves if they will not willingly come to them on their own.
* In the second to the last episode of {{Gundam 00}}, [[spoiler: Andrei Smirnov]], who is in love with [[spoiler: Louise Halevy]], attempts to do this to [[spoiler:Saji Crossroad, Louise's [[StarCrossedLovers long-distanced boyfriend]], [[FreudianExcuse blaming him for her deteriorating condition]].]] Luckily, [[spoiler: Setsuna]] is there literally (their [[CombiningMecha mechas]] anyway) just behind [[spoiler: Saji]] to prevent it.
** [[spoiler: Andrei]] is actually planning to do this as early as episode 19 (of season 2).
* The ending to the ''SchoolDays'' anime, where [[spoiler:Kotonoha]] violently Murders The Hypotenuse, [[spoiler:right after the Hypotenuse, Sekai, murders the lead, Makoto, thus killing the triangle]].
** This was reversed in the manga, where [[spoiler: ''Kotonoha'' is the Hypotenuse that ends up killed]], and in some new bad endings of the PS2 game. In one of these, [[spoiler: Sekai openly tries to push Kotonoha in the way of a train right after Makoto chooses Kotonoha over her, but [[KarmicDeath ends up hit instead]].]] Another strongly hints that [[spoiler: Sekai stabbed Kotonoha and left her to bleed to death in the streets... and Makoto knows that (and may have helped).]] [[NightmareFuel CREEPY...]]
* Subverted in ''HellTeacherNube''. [[spoiler: Yukime was killed by her father's ruthless henchman because she actually ''refused'' to kill her love rival, Ritsuko.]]
* In ''{{Mai-HiME}}'', Shiho Munakata is in love with her childhood friend Yuuichi Tate, who's in love with Mai Tokiha. When Shiho comes to believe that Mai is stealing Tate away from her (more due to Tate's actions than Mai's), she attacks Mai to keep her out of the way permanently. [[spoiler:The true tragedy is that, as Mai realizes in the fight, due to the mechanics of the whole Himelander thing going on, if ''either'' of them loses the fight, Tate will die. This doesn't stop Shiho though, as [[DespairEventHorizon she's gone through the deep end already]], and Tate finally dies.]]
* Played with in ''SpeedGrapher''. [[spoiler: DarkActionGirl Ginza is desperately in love with her friend Saiga, admits to be ''really'' jealous of his protegée Kagura (and once returns her to her mother, the one Saiga is trying to free her from) and ''does'' admit out loud that she'd love to kill her... but in the end, she decides to protect Kasgura with her life, since Saiga made her promise that she'd protect Kagura.]]
* In the Rumiko Takahashi one-shot ''Laughing Target'', the protagonist has a [[KissingCousins cousin]] to whom he made a ChildhoodMarriagePromise. However, he eventually grew up, moved on, and started dating a girl at his school. When the cousin moves in with the protagonist (after her mother's [[SelfMadeOrphan mysterious death]]), it turns out that she ''hasn't'' moved on - and she's ''very'' unhappy with the new girlfriend for taking what's rightfully hers...
* In ''MiraiNikki'', it's shown very clearly that Gasai Yuno would be all too willing to kill ANYONE who got in the way of her "love" with Yukiteru ([[SelfMadeOrphan including his mother and father]]).
** Don't say anything about her when near Yukiteru.. [[TakeOurWordForIt Just]]...[[BerserkButton don't]].
** A less lethal version of this seems to be executed by Akise Aru, who apparently has a [[HoYay gay crush]] on Yukiteru. He [[spoiler: goes through the trouble of researching everything about Yuno's background to try to dig up dirt on her, and exposes it to Yukiteru, tellling Yukiteru to "get away from her."]]
* The whole plot of ''{{Area 88}}'' is that Shin's (now former) best friend ships him off to a war in the hopes that he'll get killed, so he can marry Shin's girfriend, the daughter of his company's CEO.
* Creed from ''BlackCat'' does exactly this to [[spoiler: Saya]] when Train started developing a deep friendship with her. When that didn't manage to convince Train to come to him, Creed decides that it is now Train's [[HeterosexualLifePartners Heterosexual Life Partner's]] fault and tries to kill him.
* This almost happens in ''KodomoNoJikan''. Thankfully, the would-be perpetrator doesn't push the love rival down the stairs. It's still creepy.
** The suspense nearly gave ThisTroper a heart attack. The word creepy doesn't even begin to describe that scene, considering that the 'perpetrator' is [[spoiler:''nine years old'']].
* Genkaku from ''DeadmanWonderland'' attempts this ''twice'' with the girls he thinks Nagi is interested in. He stabs Karako when she gives Nagi a CooldownHug, calling her a "shitty girl," and telling her not to touch Nagi. He also is shown to be very agitated and jealous when he insinuates that Shiro is someone close to Nagi, saying that Nagi "never learns," and that he'll just have to punish him again (which he tries by attempting to have Shiro and Karako raped). It's especially interesting to note that ''he'' was also the one that killed Nagi's wife in the beginning.
* ''FullMetalPanic''. When it comes down to it, this is pretty much what [[spoiler: Gauron]] tries to do to Kaname, because he's angry that Sousuke fell in love with her.
* In HigurashiNoNakuKoroNi, his was Shions solution to the problem that her crush Satoshi was spending all his time caring for his little sister Satoko and not realizing the {{Yandere}} existed (Literally. She always made a TwinSwitch with Mion before they talked). And this is when she was sane, when she snaps ItGotWorse and she decides to KillEmAll
* A variant of sorts occurs in ''FistOftheNorthStar'' in regards to Shin, Yuria and main hero Kenshiro. Shin is in love with Yuria, who is in a relationship with Ken. The variant here though is that Shin seems relatively self-restrained... until Jagi, Ken's arsehole brother, comes along and convinces Shin that Ken is too weak to protect Yuria and that Yuria would end up dead if she stayed with Ken any longer. Result? Shin and Ken fight, Ken loses, Yuria declares her false love for Shin to spare Ken's life and he takes her to his Southern Cross kingdom and some time later, Ken confronts him there. Fans know how the story goes from there.
* Loli and Menoli of {{Bleach}} attempt to do this to [[TheMedic Orihime]] due to their [[BigBad boss]] having an interest in her [[BarrierMaiden powers]], and possibly [[MostCommonSuperPower those powers]] too.
* AngelSanctuary: That's pretty much the motivation for Rosiel's schemes against Sara. Alexiel won't wake up permanently (shows up in moments of need but always gives back the control to Setsuna) because her current reincarnation is extremely happier. So Rosiel figures that if Setsuna could not be happy anymore... And yes, Rosiel and Alexiel are brother and sister, but that barely matters to the point of this trope. And even if it did, Sara and Setsuna are too, but that didn't keep her from being overjoyed when [[spoiler:she believed to be carrying his child.]]
** And on a more straight example, Layla set up her (succesfull) love rival to be killed ''by the man they both loved''. Pretty cruel for all of the involved.
* Suruga from ''{{Bakemonogatari}}'' is infatuated with Hitagi. So much so that she starts stalking Koyomi after he hooks up with Hitagi and tries to beat him to death ''twice''.
** Doesnt manage only because of Koyomi's amazing regenerating ability. [[spoiler:I bet having been thrown around the room and then [[HighOctaneNightmareFuel pulled back by your intestines]] would kill a normal person]]

[[folder: Comic Books ]]

* During the "Return of the King" storyline in ''[[UltimateMarvel Ultimate]] Comicbook/{{X-Men}}'', after Cyclops goes missing on a mission to the Savage Land with Wolverine, rumors start floating around that Wolverine killed Cyclops so he could be with Jean Grey. But it turns out that [[spoiler:the rumors are, in fact, ''completely true''. This comes as a special surprise if you're used to the main universe's Wolverine, who goes by samurai honor codes and such.]]
* Strange example: Thanos cursed {{Deadpool}} [[CursedWithAwesome with immortality]]. The catch? Thanos's love interest, Death, is herself in love with Deadpool and the feeling is mutual. By keeping Deadpool alive indefinitely, he won't be able to cockblock Thanos.
* One EC Comics story had two stories in one involving the same characters: "Murder the Lover" and "Murder the Husband." In the first, the husband finds out his best friend is having an affair with his wife, and invites the friend up to his forest cabin with murder on his mind. In the second, the husband is ignorant of the affair, and the friend takes advantage of an innocent invitation up to the forest cabin to get the wife for himself once and for all. As predictable in EC comics, neither plot ends well for the perpetrator.
* ''WhateverHappenedToTheManOfTomorrow?'' does this to ensure that Superman can have his happy ending. [[spoiler: Lana's HeroicSacrifice makes it very easy for Superman to end up with Lois, whom he declares to be his true love.]]

[[/folder]]

[[folder: Film ]]

* ''Film/{{Orphan}}'': All of [[spoiler: Esther]]'s actions in this film have in mind the ultimate death of [[spoiler: Kate, Danny AND Maxine]] so that she can have [[spoiler: John]] all to herself.
* In ''BatmanAndRobin'', Poison Ivy deactivates Mr. Freeze's IllGirl wife Nora from her life support system and blames it on the heroes - and in the process, she's able to convince him to take revenge on all of humanity by freezing the world and leaving her and him as the ''only'' people alive. [[spoiler: Freeze learns, once his plan is undone, that the good guys actually saved his wife and that Ivy was the one who tried to kill her, prompting a HeelFaceTurn]].
* Gaston in ''BeautyandtheBeast''. "BELLE IS MINE!!!"
* Caledon Hockely in ''{{Titanic}}'' comes to this conclusion when he finds out that his fiance Rose loves Jack more than she loves him.
* David Allen Griffin from ''Film/TheWatcher'' does this with all of Joel's love interests. He wants to make sure that Joel [[FoeYay only thinks about and chases after]] ''[[FoeYay him]]'', and any woman getting in the way is just [[{{Yandere}} asking for death]].
* In the 1986 version of ''TheHitcher'', John Ryder does this to Jim Halsey's [[OfficialCouple female love interest]]. Apparently, not only is he [[StalkerWithACrush obsessed with stalking Halsey]] and having FoeYay with him, he also wants to make sure that Halsey doesn't have a girl by his side.
*In Howard Hawks 1939 film, ''Only Angels Have Wings'', Cary Grant's character orders a pilot to fly in foggy weather so he can have dinner with the other pilot's date. He ends up ordering the man to return to the airport, but after an unsuccessful landing attempt, he tells him to simply fly around until the fog lifts. The man is too eager, however, to make that dinner date, and ends up crashing his plane and dying. It isn't exactly murder--but when Cary Grant's character shows absolutely no regret for his actions and also says the other pilot wasn't a good enough flier otherwise he would have survived, it comes across as especially cold.
* [[TheChessmaster Lady Kaede]] in ''{{Ran}}'', as part of her scheme to [[spoiler:bring down the House of Ichimonji, manipulates Jiro to murder his wife, Lady Sue.]]

[[/folder]]

[[folder: Literature ]]

* The story of King David and Bathsheba in the Bible (2 Samuel 10-12), where the king [[TheUriahGambit sends a general named Uriah on a suicide mission]] because he fancies Uriah's wife, makes this OlderThanFeudalism.
** He paid for it. Oh, did he pay for it. [[spoiler: When God actually bitches you out and then the first child you have with your now-wife dies... Not to mention that it indirectly caused his other sons to rebel and try to kill him]]. Poor King David.
*** Poor King David? He got what he deserved. Poor Uriah!
* Reversed in AgathaChristie's classic ''And Then There Were None''. The man General [=MacArthur=] sent off to his death was his right-hand man, and was carrying on an affair with Mrs. [=MacArthur=]. [[spoiler: And that crime was what prompted the Judge to kill him in the first place, though he was among the first victims since he ''did'' regret what he had done, so the assassin considered him to be less guilty than, say, the teacher girl who caused her little pupil's death so her fiancé inherited the family estate.]]
** Christie also used the trope in ''Sparkling Cyanide''. The initial murder is committed by [[spoiler: the victim's husband's secretary, who is in love with the husband and believes he would turn to her if the wife was out of the way. He doesn't, so in order for her murder to not be in vain, she engineers a convoluted series of follow-up murders designed to eventually give her control of the family fortune.]]
* The SherlockHolmes story "The Crooked Man" features a military officer who betrays an underling to the enemy so he can steal his girl. Unlike the David and Bathsheba legend (which the story references), the underling survives (despite ColdBloodedTorture from the enemy). His condition is such that he avoids his old love out of [[DontYouDarePityMe fear of pitying]] him, but he comes back eventually, his love recognizes him, and the false husband dies of stroke on learning of it.
* Touched on in ''HarryPotter and the Deathly Hallows''. Severus Snape is perfectly fine with Voldemort murdering both James and Harry (the latter of whom is ''barely a year old at the time'') if it leaves the field clear for him to [[ComfortingTheWidow comfort the grieving widow]]. A disgusted Dumbledore calls him on it.
* The a major subplot of the novel ''[[LoisMcMasterBujold A Civil Campaign]]'' featured Miles Vorkosigan [[MaliciousSlander being accused]] of doing exactly this during the events of the previous book ''Komarr'' (in order to free up the woman he was now attempting to court) by political opponents. The truth being part of an ultra-classified incident that couldn't even be revealed to some of the highest levels of government (if the bereaved hadn't been a direct witness, ''she'' wouldn't even have known), so things got rather... complicated.
* Instead of getting killed, Edmond Dantes, a.k.a. [[spoiler:TheCountOfMonteCristo]] gets sent to the hellish prison named Chateau d'If, all thanks to a conspiration mostly engineered by his "best friend" Fernand so he can have Mercedes, Dantes' fiancee.
* In ''TheBrothersKaramazov'', [[spoiler:Smerdyakov]] thinks this will be the natural result of baiting Dmitri with a BriefcaseFullOfMoney in the lair of his romantic rival.
* In the BenBova novel "Mercury", the story starts with Mance Bracknell, lead engineer on a space elevator, married to Lara Tierney. Victor Molina, astro-biologist best friend of Mance, wants Lara. When the space elevator collapses, killing hundreds of milllions of people and devastating many nations, [[spoiler:Victor falsely testifies in court that Mance was negligently responsible for the collapse, getting him put into forced labour for life. After an accident wipes out everyone on a spaceship but him, Mance takes on the identity of one of the crew members and (eventually) gets a job as manager of a colony on Mercury. He lures Victor (who is now happily married to Lara) to Mercury with some life-bearing rocks he's planted, with the goal of getting Victor publicly humiliated when his astro-biologist peers inevitably discover that the rocks aren't from Mercury (thus showing him as either a fraud or an idiot, either way ending his career). Mance seems to think this will get Lara back, but when he reveals his identity, plan, and Victor's false testimony, Lara rejects them both]].
* In the first book of ''The Binding of the Blade'' series by L.B. Graham, there is a LoveTriangle between [[TheHero Joraiem Andira]], [[JerkAss Rulalin Tarasir]], and [[TheChick Wylla Someris]]. Rulalin was Wylla's UnluckyChildhoodFriend, and hadn't seen her for a few years prior to the beginning of the book. He had been hoping to convince her to marry him because when he had first confessed his feelings for her she had been in the midst of grieving her dead father. Naturally, he wasn't happy [[LoveMakesYouCrazy at all]] when she continued to reject his advances and instead chose to marry Joraiem. About a month after their wedding, Rulalin [[spoiler:lured Joraiem down to a remote spot and tried to convince Joraiem to murder him because life had no meaning if he couldn't marry Wylla. Joraiem, shocked, refused, so [[LoveMakesYouEvil Rulalin stabbed him instead]]. [[HerHeartWillGoOn Fortunately, that wasn't the end of the Andira bloodline...]]]]
* In Dan Brown's ''Digital Fortress'', Susan Fletcher's boss Trevor Strathmore is in love with her and attempts to [[spoiler:have her boyfriend killed]] to win her over. This backfires massively when [[spoiler:she comes across his pager showing the hitman's report]].
* [[JohnnyBGoode This troper]] once read a book where a guy actually murders (both the woman's husband and son, so make it double) the hypotenuse once, and then two years later when the woman gets involved with a cop, he tries to kill the hypotenuse again using the same method (He fails this time).
* In EdgarRiceBurroughs's ''[[JohnCarterOfMars Princess of Mars]]'', after Dejah Thoris believed John Carter died and promised to marry a foreign prince, she explains that they have laws to prevent this trope: she can not marry the man who killed her fiance. He carefully arranges that someone else kill him in their attack.
** In ''Thuvia, Maid of Mars'', Carthoris sees that a beleagured ship is that of Kulan Tith, betrothed to the woman he loves, and is tempted to sail on, leaving him to his death. He doesn't, of course, even though Kulan Tith himself comments on the HeroicSacrifice entailed.
** In ''The Master Mind of Mars'', when Ulysses Paxton revives Dar Tarus from FauxDeath and proposes his man against Xaxa, Dar Tarus is eager: he reveals that, in the BackStory, Xaxa had sent him to this FauxDeath so her favorite could woo the girl who loved him.
* Geoffrey Clifton in TheEnglishPatient, when he finds out about the title character's affair with his wife, tries to kill him. [[IfICantHaveYou And the wife.]] And himself.
* Victoria in Charlotte Dacre's Gothic novel ''Zofloya; or, The Moor'' poisons her husband to free herself to pursue his brother Henriquez, and then murders Henriquez's beloved in order to get rid of the competition.

[[/folder]]

[[folder: Live Action TV ]]

* An episode of ''LawAndOrder'' features the rather creepy example of a man who, obsessively in love with his best friend's wife, murdered him and framed it to [[MakeItLookLikeAnAccident look like an accident]]; the grief-stricken wife later independently fell in love with and married the best friend, completely unaware that she was marrying not only the man who murdered her husband but her own stalker.
* In ''{{Lost}}'', resident MagnificentBastard Ben Linus had a crush-turned-obsession on Juliet. She, on the other hand, was with Goodwin. You don't need a degree to figure out what happens to the poor fool.
* In ''{{Rome}}'', it's pretty much standard procedure to kill someone in the event of any romantic complication. Need your daughter for a political marriage? Have her husband killed. Found out your best friend's wife has a child by another man? Kill him and dump him in the sewer. Want a married man? Poison his pregnant wife!
* In ''{{DesperateHousewives}}'', this happens when Bree tries to get back to her cheating husband Rex by going out with George, the local pharmacist and {{Stalker With a Crush}}. Eventually she realizes that she considers George just a friend and goes back to Rex, who had recently had a heart attack. George then continuously switches Rex's pills until he dies and then proceeds to date Bree again.
*''{{Coronation Street}}'' recently played out this trope. When Tony Gordon learned that his fiancee Carla Connor had feelings for her former brother-in-law Liam Connor, he arranged to have Liam run over.
* In ''{{Oz}}'', Ryan O'Reily orders his brother to kill Dr. Nathan's husband, thinking he could win her over if her husband was gone. Sad thing is that [[spoiler: he was right]].
** The fact that he also [[spoiler: killed the man who raped her, which is possibly the only time he's gotten his own hands dirty as he usually manipulates others into doing the deed for him,]] had a lot to do with it.
*** Chris Keller in the same show, is arguably a male {{Yandere}} over Beecher, since he basically kills all of Beecher's previous lovers.
* Two-thirds of all ''{{Monk}}'' episodes involve this.
* A deliberate example of this is attempted by a character in ''TheSarahConnorChronicles.'' [[spoiler: Jessie]] pushes [[spoiler: Riley toward John]] in an effort to force [[spoiler: [[RobotGirl Cameron]] to consider her a threat, and thefore force Cameron to kill Riley, all in an effort to alienate John and Cameron.]]

[[folder: Music ]]

* Essentially the theme of the song "Rocky Raccoon", by TheBeatles.
* "Jenny Again", by Tunng. The titular Jenny is the equivalent of the example's Alice: the listener is put into the position of Bob, and the singer is in the position of Chris.
* "Bloody Valentine" by Good Charlotte

[[/folder]]

[[folder: Fan Fics ]]

* This is the premise of many bad fanfics, in that one character (usually [[CharacterDerailment unfairly demonized relative to their canon portrayal]]) attempts to kill a second [[DieForOurShip to get possession of their love interest]]. What usually follows from this is that the third character rides to the rescue of the second and fluffy romance and/or sex ensues. Character 2 or 3 is often a MarySue.

[[/folder]]

[[folder: Tabletop Games ]]

* Happens in the continuing example game in ''BlissStage'', prompted by Josh asking Keenan what he thought of the love interest Sara. His response: "Man, she's getting all ''girly'' and ''clingy'' and shit. [[KickTheDog Lousy lay, too.]]"

[[/folder]]

[[folder: Theater ]]

* ''{{Medea}}'': The original WomanScorned, she killed her husband Jason's new fiancée after being dumped for her. This wasn't an attempt to win him back, however, but pure and simple revenge, particularly when she also put her children by Jason to the sword just to make him suffer all the more.
* In ''SweeneyTodd'', Judge Turpin fancies Benjamin Barker's wife, and has him convicted of a crime he didn't commit and shipped off to Australia to get him out of the way. However, as in ''The Crooked Man'' example above, he escapes from prison and returns to get his revenge on the judge.
* Somewhat subverted in ''TheCrucible''. [[{{Yandere}} Abigail Williams]] is in love with John Proctor, and tries to get Proctor's wife Elizabeth hanged as a witch. Due to a bit of DeusExMachina, [[spoiler:she not only fails, but gets Proctor himself hanged instead.]] Oopsie.
* In ''LittleShopOfHorrors'', Seymor almost does this with Audrey's boyfriend Orion. He loses his nerve, but Orion dies immediatly afterward through his abuse of his laughing gas and Seymor's inaction. Of course, this is less because he's dating Audrey and more because he's abusing her.

[[/folder]]

[[folder: Video Games ]]

* A variation in ''SuperRobotWars W'': Aria wants to kill Kazuma over his ''sisters''. Makes a bit more sense when you learn that Aria is [[spoiler: sort of an OppositeSexClone of Kazuma, loving his sisters as if they were her own and hating him for having "her" place in the family.]]
* One of the possible endings of a sidequest in JadeEmpire, best described as "childhood promise gone wrong". Once you gather the poor man, the mobster woman he "promised" to marry (at all of about eight), and his fiancee, you could convince the mob boss to call off her pursuit... or, convince her to kill the fiancee. Which she does. At which point, the man rightfully objects - so she kills him. Finally, having [[WhatHaveIDone realized she didn't mean it]], she tries to kill ''you''. [[NiceJobBreakingItHero Good job]], [[KicktheDog jerk]].
* In BaldursGate II, NPC Aerie can be romanced by both the player character and fellow NPC Haer'Dalis. If she chooses you, he'll back down, but if her romances with both proceed at about the same pace, he tries to settle things in this manner.
* In ''{{Tsukihime}}'', [[spoiler:Arcueid tries it on Ciel in Ciel's route, SHIKI tries it on Shiki in Akiha's route, and finally Akiha tries it with Kohaku ''and'' Shiki in Kohaku's route]].
* [[spoiler:Sakura, despite having already won, tries this on Rin]] in ''FateStayNight'' as part of [[TheMinnesotaFats her massive inferiority complex and already present envy]]. Apparently normal, healthy relationships are the exception in the {{Nasuverse}}.

[[folder: Webcomics ]]

* Szark considered killing Luna so he could be with Dominic in ''DominicDeegan: Oracle for Hire''. This was a residual effect of the demonic wound that had gotten him addicted to killing, and [[http://www.dominic-deegan.com/view.php?date=2005-11-03 he resisted the temptation to even daydream]]. On the other side, Karnak really ''did'' try to kill Dominic's father in order to claim his mother.
* Oasis from SluggyFreelance is almost perpetually two punch daggers away from murdering even a vaguely perceived hypotenuse, and Torg lives in fear that it will eventually be Zoe, which it almost has been. The ''Fire and Rain'' arc revolved around Oasis' deranged and Determinator stalking of Zoe.
* Halfway averted in the love hexagon that is Starscream's Brigade in the ''{{Insecticomics}}''. While Dreadmoon doesn't actively try to kill Skyfire, the partner of his long-time crush Starscream, he has occasionally directed some "friendly fire" his way and sent him threatening Mini-Cons.

[[/folder]]

[[folder: Western Animation ]]

* One of ''TheSimpsons'' Treehouse of Horror episodes centers around an house with AI that's in love with Marge. Homer [[TooDumbToLive explicitly points out]] that Marge would be available to "man or machine" if he were to die.
-->'''AI:''' Machine, eh?
-->'''Homer:''' Yep, a machine!
*''DannyPhantom'', where Vlad constantly tries to kill his "best friend" Jack in order to win his wife Maddie's heart. He has a creepy, stalkerish relationship with Jack and Maddie's kid and main character Danny.
* Subverted in ''JusticeLeagueUnlimited'': Shayera/Hawkgirl and Mari/Vixen, two legs of a LoveTriangle (with the other being GreenLantern John Stewart), are caught in a trap and hunted down by Thanagarians who want to execute Hawkgirl for war crimes. Vixen gets captured and immediately strikes a deal with them -- spare her and she'll deliver Hawkgirl to them, going as far as to cite the LoveTriangle as the reason she'll betray her superior so quickly. [[spoiler: The subversion is that she doesn't go through with it -- ''nor did she ever plan to''. Once the Thanagarians let their guard down and bring her to their aircraft, she hijacks the thing so she can get both herself ''and'' Hawkgirl out of there safely.]]
* Played (relatively) straight in ''FamilyGuy'' when Stewie falls for his new babysitter, only to learn that she has a boyfriend. He then kidnaps her boyfriend, breaks his legs, ties him up and locks him in the back of Brian's car, ultimately leading to his death. Stewie then prepares to make his move on Ledan, only to realise that she's completely broken up about her boyfriend. Arguably subverted at the end where Stewie receives a gift from her and assumes that she does like him (of course, considering he's a baby and she's a teenager, this is hopefully not the case).
* In {{Futurama}}, Bender says he assumed Fry was only pretending to love his old dog to mess with Bender's emotions (not a romantic love triangle, but love nonetheless). So, he throws the dog into lava.
-->'''Bender:''' Now I'm all you've got!
** Of course, the dog is a fossil and thus already dead. Otherwise it would probably have been Bender's MoralEventHorizon had he done it to a ''live'' dog. Also, once he realizes that Fry genuinely loves his dog he [[spoiler: dives into the lava to save the dog]].
