7	->''"Military leaders since the city-states of early Greece have known that a tried and tested method for getting rid of a dangerous adversary is to provoke him into attacking another powerful enemy. Provide an ambitious adversary with the backing of a seemingly invincible army, and he's bound to go after even his toughest rivals. Making sure your adversary is eliminated then becomes about pulling that backing once he's declared war on his rival. When it's too late for him to take it all back."''

10	Betrayal comes in all kinds of forms, one of them being characters turning their backs on former allies and walking away, abandoning them to their fate without so much as having to lift a finger. Or even just standing there as the ex-ally is demanding that they [[GiveMeASword give them a weapon]].
11
12	Sometimes this is part of an UriahGambit, when the traitor specifically created the situation in which their former ally would need their help. Other times it is the result of a FairWeatherFriend. BodyguardBetrayal often happens this way. A [[KickTheDog particularly cruel variant]] occurs if the traitors simply stand there and laugh at their former friend's misfortune.
13
14	The phrase associated with this trope is "left in the lurch".
15
16	Compare MurderByInaction, AccompliceByInaction, and CavalryBetrayal. Contrast with ScrewThisImOuttaHere, when the deserters are merely trying to save their own hides but gain nothing from their allies' defeat (i.e. betrayal is not their intention as in this trope). Contrast also FailureToSaveMurder when they ''did'' try to save the person, but failed.

25	* ''Manga/BlackClover'': Julius' scheme to obtain Lucifero's heart went as he said it would, including the defeats of his younger siblings the Dark Triad (with Zenon killed at that), ultimately leading to the magic knights killing Lucifero for Adrammelech to take his heart for Lucius.
26	* In the anime adaptation of ''Literature/SchwarzesMarken'', Heinz Axmann offers to send some Stasi troops to help repel the [=BETA=] offensive. Unfortunately when the battle actually starts, he's just sitting on his butt and doesn't send any of his troops out to help.
27	* In ''Anime/ValvraveTheLiberator,'' Akira's brother Satomi did this to her [[spoiler:after he got her to hack a school's entrance exam website for him, then pretended he didn't know anything about it when she got caught. When she was bullied over it, he ignored her then, too]]. He tries to make amends years later, in the time the series covers, but that's not so easy.

30	[[folder:Comic Books]]
31	* ''ComicBook/BlackMoonChronicles'': When Emperor Haaghendorf and his army are about to fight the evil forces of the Black Moon, he calls upon the two autonomous military orders to assist him. The Knights of Light led by Fratus Sinister arrive on the battlefield but stay out of any fighting in the hopes that Haaghendorf will be killed and they can seize power from whatever's left, even [[ShootTheMessenger shooting numerous imperial messengers]] sent to ask them for reinforcements. However, Haaghendorf sees through this deception and demotes Fratus Sinister after winning the battle singlehandedly.
32	* At the end of ''ComicBook/FearItself: Youth in Revolt'', Thor Girl, having transformed into an EnergyBeing, returns to her home galaxy after growing disgusted with humanity's inability to work together and deciding that Earth doesn't deserve her protection.
33	* ''ComicBook/IronFist1975:'' As Master Khan reveals to Danny, Yu-Ti knew the Rands were coming to K'un-Lun on the day it would reappear, having magic to spy on his half-brother Wendell, so he knew Harold Meachum had shoved his brother off a cliff, and knew Danny and his mother were wandering the Himalayas. But his men only showed up to save Danny ''after'' his mom leapt into some hungry wolves. Danny is initially shocked to hear this, but Yu-Ti doesn't deny it.
34	* ''ComicBook/{{Thunderbolts}}:'' When the team ignores Zemo's order to let the Elements of Doom roam free and go off to fight them anyway, Zemo follows and watches as the Elements overwhelm them. He decides not to get involved to teach them a lesson about disobeying him, and that if any of them die, no big loss, since he can just replace them.
35	* TheReveal of ''ComicBook/WorldWarHulk'' has it that one of the Hulk's Warbound: [[spoiler:Miek]] was partially responsible for Sakaar's destruction by allowing factions opposed to the Hulk as their ruler to overload the warpcore of the spacecraft he came in. He did this because he believed that the Hulk would then realize his destiny as the "World Breaker" and fulfill a Sakaaran prophecy.

38	[[folder:Fan Works]]
39	!!{{Crossover}} Works:
40	* ''[[https://archiveofourown.org/works/46463032/chapters/116987404 #8024]]'': When Marinette is falsely accused of working with Hawkmoth, subjected to a KangarooCourt and shunted off to [[Franchise/{{Batman}} Arkham Asylum]], Chat Noir refuses to lift a finger to help her, not caring one whit about her fate. He justifies this by claiming ''Ladybug'' signed off on the arrest, unaware that [[SecretIdentity Marinette IS Ladybug]].
41	* ''Fanfic/CardcaptorRad'': In ''Glowing Teamwork'', Rad befriends [[spoiler:the Deception mini-cons]]... but when Megatron comes after him, they make no effort to intervene, leaving him to lament their inaction.
42	* In ''Fanfic/TheDefendersOfRemnant'', Taskmaster abandons their ally [[spoiler:Kingpin]] during the heist at the docks, allowing the Punisher to finish them off.
43	* ''Fanfic/AKingdomCalledSugarRush'': Turbo was close friends with Queen Candice, but also [[AmbitionIsEvil coveted the power he'd gain]] after her passing. When he heard her having a deadly coughing fit, he hesitated before retrieving the potion she was taking to combat her illness. This hesitation leads to her death, forcing him to live with the guilt.
44	* ''Fanfic/RaiseYourVoiceAgainstLiars'': Despite claiming to be on Marinette's side, Adrien stood by and watched Lila steadily turn the rest of the class against her with her lies, refusing to speak out against the ManipulativeBitch or defend Marinette. As a result, Marinette considers him to have [[EtTuBrute betrayed her]] just as severely as [[{{Hypocrite}} Alya]] did.
45	* ''Fanfic/ThreeCanKeepASecret'': In the outlined epilogue, this results in the fall of [[spoiler:the land of Mewni]]. Everyone who had pledged to assist [[spoiler:the Butterflies]] in the past decide to throw in their lot with [[spoiler:the Lucitors]] instead, letting them launch their invasion unchallenged.
46	* ''Fanfic/ZeroRequiem'':
47	** Daemon advises his uncle against trying to claim the Iron Throne during Lyonel Baratheon's rebellion. Maelys convinces himself that this was an act of treason against House Blackfyre, and murders his cousin for it.
48	** After conquering Myr, Lashare chooses to play AchillesInHisTent by not sending any real aid to Maelys or his forces. While Maelys sees through this, he's unable to retaliate, given how he has bigger concerns dealing with the Westerosi army.
49
50	!!''Franchise/AvatarTheLastAirbender'':
51	* ''Fanfic/AbsoluteTrust'': [[Recap/AvatarTheLastAirbenderThePuppetMaster Hama]] is shown to be more despicable than in the show; while she used her [[ThePowerOfBlood Bloodbending abilities]] to escape from [[TailorMadePrison Water's Wail]], she didn't bother releasing the ''other'' Waterbenders who were imprisoned there. Nor did she make any attempt to rescue them in the ''three decades'' that followed, while she spent that time performing inhuman Bloodbending acts against innocent Fire Nation civilians.
52	-->''[[TheSocialDarwinist The others had seen enough Bloodbending to learn it on their own, but if they were too weak or didn't have the stomach for it, than why should I save them?]]''
53
54	!!''Franchise/CharlieAndTheChocolateFactory''
55	* In ''Fanfic/NuttyForWonka'', Matilda internally debates with herself over whether or not she should try and save her cousin Veruca and Uncle Nigel. Ultimately, [[spoiler:she decides to save them despite Wonka telepathically encouraging her to let them suffer]].
56
57	!!''Franchise/{{Danganronpa}}'':
58	* ''Fanfic/DanganronpaDespairsPhilosophy'': In the final dream of Chapter 3, [[spoiler:Mr. Demar]] does nothing to help Lydia while she's being harassed and pursued by [[spoiler:an obsessive Nagito]]. This sets the tone for all of their interactions with each other afterwards.
59	* ''Fanfic/FracturedFates'': In Chapter 5, Monokuma reveals that one of the still-living students didn't suffer from LaserGuidedAmnesia like the rest of their peers. What's more, they knew the true nature of the killing game and almost everything about it from the start. Monokuma declares that the fact they didn't use this knowledge to stop the game before it began makes them a 'traitor' to the rest of their class.
60
61	!!''WesternAnimation/DannyPhantom''
62	* ''Fanfic/DannyPhantomStranded'': In ''Staged'', Star explains to Danny that she [[WeUsedToBeFriends used to be closer]] to her cousin Christopher before she [[ToxicFriendInfluence joined the A-Listers]]. When Dash pulled an incredibly cruel prank on the Poil Junior High's football team and their mascot, Christopher (who attended that school) stepped up to confront and call them out... but this just turned him into a target for Dash and the other jocks, while Star pretended not to know him. Star now [[PostSupportRegret deeply regrets choosing the A-Listers]] over her cousin, but isn't sure how to repair their relationship.
63
64	!!''TabletopGame/DungeonsAndDragons''
65	* ''Fanfic/VowOfNudity'': After getting told off by the father of the boy she dumped, Fiora stows away on his hunting trip and witnesses him get ambushed by an axebeak, but intentionally chooses not to warn him. This lets the bird get the drop on him and savagely maul him before he could even react.
66
67	!!''Franchise/Hellaverse''
68	* ''Fanfic/HelluvaDad'': PlayedWith through Travers; while he was the one who stabbed [[spoiler:Moxxie]] in the first place, much is made of his willingness to let them bleed to death.
69
70	!!''Literature/TheHungerGames''
71	* ''Fanfic/CheckmateAnlaShok'': President Coin has an opportunity to rescue all of the 3rd Quarter Quell tributes before the games start (and has told those of them involved in the rebellion that she will save them), but she makes the cold decision to do nothing until Mags is dead in order to eliminate a potential rival and arouse more anger against the Capitol.
72
73	!!''WesternAnimation/MiraculousLadybug''
74	* Generally speaking, this is a quite common [[FandomSpecificPlot/MiraculousLadybug Fandom-Specific Plot]] for {{Accusation Fic}}s in the wake of [[Recap/MiraculousLadybugS03E01Chameleon "Chameleon"]]. Much is made of the fact that Adrien knows the truth about [[ManipulativeBitch Lila]], but opts to stand by and let her lies go unchallenged, advising Marinette not to do anything either. DependingOnTheAuthor, he often either [[MyGodWhatHaveIDone comes to realize his mistake]] or maintains a HolierThanThou attitude, or simply stays quiet because he doesn't want to risk anyone turning on ''him'' for [[CassandraTruth telling the truth]].
75	* ''Fanfic/BurningBridgesBuildingConfidence'' has Adrien pull this twice over:
76	** As Chat Noir, he combines this with CavalryRefusal by opting not to help Ladybug against akuma unless she admits that she needs him. Not just as her partner, but as her ''[[RelationshipUpgrade partner]]''. An exchange between Marinette and Tikki before they face Nightify reveals that isn't the ''first'' time he's pulled such a stunt; it just happens to be the first time that Cole and Master Fu witness it. [[WhatTheHellHero Neither is pleased]].
77	*** This escalates to the point that he stands by and lets Vexxin face off ''alone'' against three akuma at once while hissing that she ''deserves'' to be brutalized.
78	** Adrien is also fully aware that Lila is a BitchInSheepsClothing who's manipulating their classmates, turning them against Marinette and Cole ''[[GullibleLemmings en masse]]''. Rather than doing anything to help them, however, he stays out of the conflict, claiming that he's 'taking the high road' and blaming ''them'' for their troubles. After all, if they just let her lie, she'd leave them alone... so [[InsaneTrollLogic surely that means]] it's ''their'' fault that they're suffering.
79	* ''Fanfic/{{The Cosmos\|MiraculousLadybug}}'': Adrien and Nino both fall into this; Adrien [[SelectiveObliviousness feigns ignorance]] about the impact of Lila's cruelties so that he doesn't have to reconsider his stance, while Nino only ''suspected'' that something was amiss with her tall tales, but still chose to go with the group rather than trusting his instincts.
80	* ''Fanfic/{{Couturiere}}'': Despite seeing how Lila has successfully turned most of their classmates against Marinette with her MaliciousSlander, Adrien still refuses to intervene. This results in her being turned into the titular akuma. When he tries encouraging her to [[IKnowYoureInThereSomewhereFight fight back]], claiming he knows that she's better than this, Couturiere [[WhatTheHellHero calls him out]] on not trying to remind ''anyone else'' of her "better nature" before:
81	-->'''Couturiere:''' Today in class, I just wanted it to ''stop!'' I was getting closer and closer to the edge, and I needed someone, I needed ''you'', to just stand up and say 'I know Marinette Dupain-Cheng, and she is no monster!' And yet... you just sat there. I needed you to catch me... and you let me fall. So tell me, Agreste: after how everything went down after listening to your ''stellar'' advice... why should I listen to you now?
82	* ''[[https://archiveofourown.org/works/23773411 i'll come back like a boomerang]]'' has Lila's [[LiarRevealed true nature exposed]] years after the akuma class has graduated. When Marinette makes clear that she won't forgive her [[WeUsedToBeFriends former friends]] for abandoning her, Adrien confidently declares that ''he's'' still her friend, since he knew the truth all along. Marinette retorts that that's exactly why she considers him unforgivable -- because he stood by and let Lila string everyone else along, as well as letting her be bullied.
83	* ''Fanfic/TheKarmaOfLies'':
84	** Adrien is fully aware that Lila is scamming the majority of his friends/classmates, along with turning them against Marinette by PlayingTheVictimCard. Yet he refuses to do anything about the situation because he'd rather preserve his own reputation rather than risk making anybody mad by exposing any unpleasant truths.
85	** Adrien also skips what turns out to be the FinalBattle with Hawkmoth due to his SkewedPriorities; Lila prevented him from sneaking away, and he decided Ladybug could ''surely'' handle herself, despite knowing she was [[RunTheGauntlet dealing with several akuma in rapid succession]] while trapped inside a building. This [[HoistByHisOwnPetard comes back to haunt him]], as his absence does ''not'' go unnoticed, and the public begins to suspect Chat Noir may have ''intentionally'' betrayed her.
86	* ''Fanfic/LeaveForMendeleiev'':
87	** Mme Bustier is shown to be an exceptionally poor teacher with her failure to intervene against Chloé's bullying. Marinette is stunned when her new homeroom teacher actually ''does'' step in, as she's been conditioned to believe that AdultsAreUseless and will always [[KarmaHoudini let Chloé get away with her cruelty]].
88	** Kim's CharacterDevelopment kicks off in earnest after he realizes that he betrayed Marinette by not doing anything about Chloé. In his case, his crush on the RichBitch didn't help; he recognized that what she was doing was wrong, but [[LoveMakesYouDumb kept making excuses for her misbehavior]].
89	** [[{{Foil}} Contrasting Kim]], Nino further betrays Marinette when he promises that Chloé will have nothing to do with the movie he's making. When that changes, he refuses to warn Marinette, then [[NeverMyFault blames her for his silence]] -- if he ''had'' warned her, she wouldn't have wanted to help anymore, and he couldn't have her breaking ''her'' end of the promise!
90	* ''Fanfic/MiraculousLadybugSaltShots'': ''The "High Road" Doesn't Work On Everyone'' features Adrien scolding Marinette for [[LiarRevealed exposing Lila's deceptive nature]], fully expecting the rest of their friends to join in on shaming her. Much to his surprise, everyone is instead furious about his failure to even ''try'' warning them. Alya outright accuses him of being a FalseFriend who was laughing at their gullibility behind their backs.
91	* ''Fanfic/{{What Goes Around Comes Around\|MiraculousLadybug}}'': Adrien runs into this in both identities: along with refusing to help deal with Lila, he fails to show up when Hawkmoth [[TheVillainKnowsWhereYouLive attacks the Dupain-Cheng bakery]], thanks to how he was attending a party with most of their classmates at the time. A crucial part of his character arc is grappling with the fact that not all trespasses are EasilyForgiven, and coming to terms with how [[spoiler:the majority of his classmates consider him a FalseFriend after learning how he let Lila dupe them]].
92	* In [[https://nobodyfamousposts.tumblr.com/post/184218659010/i-think-the-worse-way-adrien-could-reject this collaborative work]], Adrien rejects Marinette's LoveConfession because he doesn't like how she's been trying to expose Lila's true nature. A [[https://nobodyfamousposts.tumblr.com/post/734443964533489664/what-if-adrien-rejection-in-felix-culpa follow-up]] makes clear that he doesn't want the truth coming out because he ''knows'' the rest of the class would take his silence thus far as a betrayal, with him desperately trying to avoid publicly siding with ''either'' girl.
93
94	!!''Franchise/MyHeroAcademia''
95	* ''Fanfic/FromMuddyWaters'': While he reports what Sir Nighteye was doing to Izuku to Yuuei, Mirio regrets not taking further action against his abusive behavior. In chapter 29, Mirio feels he betrayed Izuku's trust by thinking that merely reporting Sir Nighteye's actions to Yuuei meant he could "sit on his hands" while the boy was abused.
96	* ''Fanfic/ThreeGuysGoToABarAndThenTheyBeatYouWithIt'': Aizawa didn't actually ''agree'' with Principal Nedzu's proposal to cast three of his students as villains, as he saw how this invoked Quirk discrimination. However, he didn't speak out against it. Worse, when presenting the assignment to them, he acted as though he took some [[SadistTeacher cruel pleasure]] in dumping that responsibility on their shoulders. As a result, Bakugou and Shinsou are especially resentful about his betrayal.
97
98	!!''WesternAnimation/MyLittlePonyFriendshipIsMagic''
99	* ''Fanfic/{{Discordant}}'': [[spoiler:Rosalia]] schemes to use this to harden [[spoiler:Mimic by having her let Thistleroot die]]. [[spoiler:Mimic saves him at the last moment.]]
100	* ''Fanfic/RainbowDoubleDashsLunaverse:'' Plays a part in the backstory of the Griffon king Gavril. His father was deposed by a coup, and he went to Twilight Sparkle's grandmother for help. However, the Equestrian government refused to do anything, preferring his brother's rule. Gavril's father never got his throne back, and Gavril's still a little tetchy about it, even though he has (though he admits in hindsight that if his father had received Equestria's help, it might've made things more difficult).
101
102	!!''Franchise/{{Naruto}}''
103	* ''Fanfic/{{The Moon Cries in Reverse\|Naruto}}'':
104	** For half a year, Shikaku had no idea that Anko was subjecting his son and his teammates to TrainingFromHell. When he finally found out shortly after the Chuunin Exams began, she, Ibiki and Hiruzen convinced him that they had ample reason to be concerned that Shikamaru might turn out like Orochimaru, so he swallowed his own distaste and let things continue... until Jiraiya arrived. When the Toad Sannin reveals just how hellish their training was, Shikaku is left cradling his head in his hands as he laments his decision not to act or investigate himself:
105	--->'''Shikaku:''' No wonder I haven't seen Shika lately. He's been trapped down there and I... I had the gall to think he was ''hiding'' the fact he was like Orochimaru from me, when in reality he was being made into that monster.
106	** Jiraiya feels similarly about how he effectively abandoned his godson Naruto for years, leaving him to be [[AllOfTheOtherReindeer systematically isolated by most of Konoha]], as well as vulnerable to the abuse Team Ten suffered in T&I. He reflects that if Minato is able to see what's been happening from the Pure Lands, he'll likely [[ThisIsUnforgivable never forgive him]] for letting things go unchanged and unchallenged for so long... and that he'll likely never be able to forgive ''himself'', either.
107	* ''Fanfic/{{Space to Breathe\|Naruto}}'': Kakashi proves to be an ApatheticTeacher for Sakura and Sakura ''alone'', but what truly drives her away from Team Seven is how he makes no move to address how poorly the boys treat her. As she tells Ibiki, "My teammates are so self-centred, and Kakashi-sensei does nothing to even ''try'' and fix it." This spurs her to [[PointOfDivergence take an apprenticeship]] under Ibiki while continuing to resent her former teacher for his neglect.
108	* ''[[Fanfic/ThreesACrowdNaruto Three's A Crowd]]'': Despite claiming that "Those who abandon their teammates are worse than trash", Kakashi proves to be an extremely hands-off SinkOrSwimMentor who refuses to directly address Sasuke and Uo's disrespectful treatment of Sakura. Instead, he expects Sakura to become TheHeart of the new Team Seven, despite how both boys act as though she's completely beneath their notice, [[BlamingTheVictim blaming her]] when they refuse to listen. Sakura repeatedly [[RageAgainstTheMentor calls him out on this]]:
109	-->'''Sakura:''' Despite what you may think, I don't need this team. There are at least four medics at the hospital that would likely take me on as an apprentice, especially if I showed them the skills that I've already taught myself. So from now on, I ''will not'' be the only one to put any effort into this team. Either you do your job as a sensei and ''make'' them work as a team, or you break up the team and call it a failure.
110
111	!!''Franchise/ASongOfIceAndFire''
112	* In ''[[https://www.fanfiction.net/s/11298331/1/A-different-weasel-makes-a-difference A different weasel makes a difference]]'', as in canon, Lady Barbrey Dustin sent the bear minimum number of troops to support Robb Stark in his war against the Iron Throne. This is arguably justified as the Northerners ''were'' rebelling, but when she refused to send any troops to help in the Second War for the Dawn (a war for the sake of all humanity), she entered this territory. Robb eventually gets sick of it and arrests her for treason. A pair of reviewers put it best
113	-->"what the hell was Barbey up to, to get slapped with a treason charge".\
114	"Nothing. That's the problem, she did absolutely nothing."
115
116	!!Unsorted:
117	* The backstory of ''Mind Games'' has the defecting General Geist describe his HeelRealization, when he witnessed a Jewish friend of his being sent to a gas chamber after he was sent to inspect a concentration camp.
118	-->'''Geist:''' He died knowing I was there and did nothing to stop it. [[MyGodWhatHaveIDone It is a guilt that will live with me forever]].
119	[[/folder]]
120
121	[[folder:Films -- Animated]]
122	* Subverted in ''WesternAnimation/BatmanMysteryOfTheBatwoman'' episode, where the daughter of a crime lord ([[AntagonisticOffspring who has been sabotaging her father's operations]]) is shouting to her father for help as she dangles from a ledge. He goes away, her head drops... and then the lifesaver on a rope he'd gone to grab drops down.
123	* ''WesternAnimation/TheEmperorsNewGroove'': While helping Kuzco back to the palace, Pacha falls through a bridge and lays dangling and calling for help. Rather than helping him up, Kuzco decides to leave him there and continue on; he was going to betray Pacha anyway and lock him in a dungeon, and this seemed easier. Unfortunately for Kuzco, [[LaserGuidedKarma he falls through moments later, leaving him in the same predicament]], and the two are forced to work together to save themselves.
124	* In ''WesternAnimation/{{Frozen\|2013}}'', [[spoiler:Hans]] leaves Anna to die when she had been expecting that he could perform an ActOfTrueLove to save her.
125	-->'''[[spoiler:Hans]]:''' Oh, Anna...if only there was someone out there who loved you.
126	* ''WesternAnimation/KungFuPanda1'': In the past, Shifu trained Tai Lung in Kung Fu; firmly convinced that he was the [[TheChosenOne Dragon Warrior]], he pushes him to train hard, and neglects to teach him humility and the spiritual side of Kung Fu. Shifu ultimately presented Tai Lung to Oogway, only for Oogway to sense the growing darkness in his heart and refuse him the title. Tai Lung looked to his master and father-figure for support, but Shifu just went along with Oogway's decision without even trying to argue on his pupil's behalf or console him afterwards. At that, Tai Lung snapped and went on a rampage through the Valley of Peace in an attempt to take the Dragon Scroll by force.
127	-->'''Tai Lung''': You ''knew'' I was the Dragon Warrior! You ''always'' knew! But, when Oogway said otherwise, what did you do? ''What did you do?! NOTHING!''\
128	'''Shifu''': You were not meant to be the Dragon Warrior! That was not my fault!\
129	'''Tai Lung''': ''Not. Your. FAULT?!'' Who filled my head with ''dreams?!'' Who drove me to train until my ''bones cracked?!'' Who denied me ''MY DESTINY?!''
130	* Zira accuses Kovu of this when Nuka dies in the attack on Simba in ''WesternAnimation/TheLionKingIISimbasPride.'' Kovu was supposed to kill Simba but refused and Nuka ran up the hill after Simba and got crushed by falling logs.
131	-->'''Zira''': What were you doing?\
132	'''Kovu:''': I did nothing!\
133	'''Zira''': Exactly. And by doing so, you betrayed your pride. Betrayed Scar!\
134	'''Kovu''': I want nothing more to do with him!\
135	'''Zira''': You cannot escape it! Nuka is dead because of you! You killed your own brother!
136	* ''WesternAnimation/{{Tarzan}}'': When Tarzan gets captured after boarding the ship that would take him, Jane and the rest back to England. As he's restrained by two thugs, Clayton boards the ship and uses his shotgun to call everyone to order. When Tarzan asks him for help, not only he does absolutely nothing about it; he ''actually pokes fun'' at Tarzan, hits him in the guts with his shotgun and flat-out reveals his true intentions, complete with the implication that it's Tarzan's fault all of the gorillas will soon be captured and sold at a high value in England. To top it all off, he gets the protagonist '''locked''' inside the ship right afterwards.
137	** Doubles as a UriahGambit, given it was part of Clayton's plan to capture the gorillas after knowing their exact location.
138	--->'''Tarzan:''' CLAYTON...!! Clayton, HELP!\
139	'''Clayton:''' [[HaveWeMet ...have we met?]] ''(shoves shotgun onto Tarzan's chin to lift up his face)'' Ah yes! ''[[AddingInsultToInjury The ape-man!]]''
140	* In ''WesternAnimation/TurningRed'', Mei betrays her friends by not standing up for them when her mother accuses them of manipulating her into using her panda form to raise money for 4*Town concert tickets.
141	* Weehawk, the elf warrior in ''WesternAnimation/{{Wizards}}'', will scream his lungs out with sword in hand when threatened.
142	[[/folder]]
143
144	[[folder:Films -- Live-Action]]
145	* In ''Film/{{Braveheart}}'', at the Battle of Falkirk, Lochlan and Mornay show up with their soldiers on the Scottish side, but once the battle has started and it's their time to charge, they simply turn around and leave the battlefield, as they’d been bribed into helping the English destroy the Scottish army.
146	* {{Justified}} in the famous ending of ''Film/GoneWithTheWind''. Scarlett had always been a ManipulativeBitch, but at some point Rhett has enough and simply walks away from her, her problems no longer being his concern.
147	** Scarlett herself finally starts to become disillusioned with Ashley when he doesn't say a single word in her defense after the two are caught in an innocent hug. By the time she finally realizes that she never really loved him to begin with, she also realizes that he has always let her down by failing to do something whenever she needed him to.
148	* In ''Film/TheHobbitAnUnexpectedJourney'', Thranduil does not come to the dwarves' defense against Smaug or help the refugees of Erebor. Years later, this is still a sore spot for Thorin.
149	* In ''Music/JesusChristSuperstar'', Judas actually threatens to ''not'' betray Jesus just to spite him and God's plans.
150	* In ''Film/MissCongeniality'', as Gracie frantically tries to plead her case to her superior, she is chewed out and dismissed while her partner stands there silently, never saying a word in her defense. Afterwards, she lashes out at him, who snaps, "Don't look at me like I betrayed you or something". To which she responds, "No, betrayal implies actually doing something. You just stood there."
151	* In ''Film/RamboFirstBloodPartII'', Rambo is assigned the job of sneaking into a [[UsefulNotes/TheVietnamWar Vietnamese camp]] and confirming whether or not Prisoners of War are present. When he finds an entire POW camp where several soldiers (including his old friend and mentor) are being held captive, he takes it upon himself to lead a revolt. However, when he and the escapees reach the chopper meant to extract them, the bureaucrat in charge of the mission orders the chopper to leave without them. The look on Rambo's face as the chopper flies away speaks volumes of the level of betrayal he felt.
152	* In ''Film/RoaringCurrents'', Todo Takatora notably does not bother coming to his ally Kurushima's aid despite the fact that the Japanese still had plenty of ships to throw at Yi Soon-shin's forces. His inaction and eventual retreat was caused by his disdain for the pirate-like Kurushima.
153	* ''Film/TheRunningMan''. Earlier in the movie Killian insulted his bodyguard Sven by asking him "Steroids make you deaf?" At the end when Richards confronts Killian, Killian expects Sven to protect him. The bodyguard Sven -- [[TheVoiceless speaking for the first time]] -- says "I got to score some steroids" and walks away, leaving Killian to his justly deserved fate. [[note]]For bonus points, the bodyguard speaks with [[Creator/ArnoldSchwarzenegger the same Austrian accent as Killian]].[[/note]]
154	* In ''Film/{{Serpico}}'', a precinct captain warns the title character that being an honest cop in a precinct where many of his fellow officers take bribes makes him a marked man. "They don't have to do anything to you. All they have to do is ''not be there when you need them''." [[spoiler:That's exactly what happens.]]
155	* ''Film/SecondhandLions'': When Mae brings Stan to the [=McCann=] farm in an effort to try and turn Walter against Garth and Hub and find their money, Stan takes him off for a "man-to-man talk". Mae just turns away while Stan takes her son behind the barn and tries to beat information out of him. A later conversation indicates she was aware of his abusive tendencies already.
156	* In ''Film/TheStrangeThingAboutTheJohnsons'', Joan does her best to completely fail to notice what's going on, even when she personally sees something wrong. In the worst instance, while her husband is screaming [[spoiler:during a rape by his son]], she ''turns up the volume on the television'' to drown out his cries for help.
157	* During the last days of Krypton in the ''Film/SupermanII'' movie, General Zod and his cronies are on trial for high treason. Zod calls for Jor-El to speak on his behalf, but Jor-El says nothing and ambles away. Zod is at first aghast then furious as he's banished to the Phantom Zone. Later, once he and his cronies escape the Zone and come to Earth, Zod has one huge ax to grind with Jor-El's sole living heir, Kal-El, who's known on Earth as Franchise/{{Superman}}.
158	* ''Film/TheWildGeese''. The president of an African country is overthrown by a military coup. A businessman hires a group of mercenaries to rescue him in order to use him as a bargaining chip to extract concessions from the new regime. After the president is rescued the regime agrees to the concessions and the businessman orders the plane sent to pick up the mercenaries to leave them behind so they can be slaughtered by the regime's forces. The mercenaries spend the rest of the movie trying to escape.

162	* ''Literature/BlackLegion'':
163	** In the first book, ''Talon Of Horus'', [[VillainProtagonist Khayon]] accuses his captive nemesis, Telemachon of doing this during the Siege of Terra; instead of supporting Khayon's forces as ordered, Telemachon led his troops into massacring Terra's civilian population with the rest of the [[CombatSadomasochist Emperor's Children]], leaving Khayon and his Thousand Sons to suffer a [[CurbStompBattle catastrophic defeat at the hands of the Blood Angels]]. Telemachon is unrepentant, [[RefugeInAudacity even claiming]] that [[JerkassHasAPoint at least the Thousand Sons slain because of his betrayal died as warriors besieging the Imperial Palace]], rather than being reduced to [[FateWorseThanDeath undead automatons by the Rubric of Ahriman]].
164	** In the second book, ''Black Legion'', Lheor accuses Telemachon's lieutenant Zaidu of leaving Lheor and his men to die in a Death Guard ambush by deliberately failing to respond to Lheor requesting reinforcements.
165	* Several books in ''Literature/TheDresdenFiles'' explore this trope:
166	** Played straight in ''Literature/{{Changes}}''. Molly offers to fight alongside Harry as he prepares to attack the Red Court, and Harry accepts her aid. This causes him a lot of guilt in ''Literature/GhostStory'' (when he realizes how deeply the battle scarred her), because, as Molly's mentor and friend, he shouldn't have let her endanger herself like that.
167	** Subverted in ''Literature/SkinGame''. Harry worries that he's not doing enough to hinder Nicodemus' plans (and thus 'betraying' all of Nicodemus' victims). Michael rebukes him for this, reassuring him that Nicodemus' actions are not Harry's fault or responsibility.
168	*** Also subverted in the same conversation another way: Harry feels like his friends have betrayed him, because they didn't come to visit him on his self-imposed exile, and he assumed it was because they were worried about him becoming a monster. [[spoiler: Michael points out that Demonreach, the island that Harry has been living on, is so scary even ''Michael'', a former Knight of the Cross and absolutely fearless in the face of demons and worse, can't stomach going there, and he then points out that despite that, Murphy and Thomas ''still went'' because they cared for him. Harry realizes that he's been kind of arrogant to assume that everything is about him.]]
169	* Creator/RobertHeinlein's novel ''Literature/{{Friday}}''. "Uncle" Jim Prufit shows up to take Friday to Boss' farm. When they arrive she's attacked by an enemy ambush and Prufit doesn't warn her, he simply watches while they take her. She learns later that Prufit is TheMole.
170	* The Oathbreakers in ''Literature/TheLordOfTheRings'' were cursed by Isildur when they ignored his call to join his army to fight against Sauron, even though they had pledged allegiance to him.
171	* ''Literature/TheLostFleet'': The entire plot of the series might have been touched off this way, because TheAlliance and [[OneNationUnderCopyright the Syndicate Worlds]] were so evenly matched that if they went to war it would end in a stalemate, and their leaders knew it: The only sane reason one side or the other would mount a surprise attack was if they had some hidden advantage... The protagonist even notices a number of oddities about the early days of the war, such as several important military targets that the Syndics inexplicably ignored during their initial offensive. Eventually he puts it all together: [[spoiler:The Syndics (and maybe the Alliance as well) had been promised military aid by a third party who went back on their word, intending to let the two nations soften each other up before rolling in and conquering both.]]
172	* In the ''Literature/MalazanBookOfTheFallen'', Lady Envy is said to have stood by while her then-lover [[FamedInStory Anomander Rake]] [[FateWorseThanDeath killed]] her father and took his SoulCuttingBlade [[ForgedByTheGods Dragnipur]] from him. It is heavily implied that she did this just to spite Lord Draconus, and because she wanted Dragnipur for herself in the long run, not to stay out of a conflict between her father and her lover.
173	* In ''Literature/ShadowPuppets'', former ally Suriyawong becomes TheDragon for Achilles, who seeks to conquer the world. Suriyawong knows that Achilles has [[TheFarmerAndTheViper killed those who gave him help]], so he always frames his aid as just giving his boss the tools to solve his own problems, such as a knife to escape his captors. When Achilles is finally confronted by his rival Bean, who's pulled a gun on him, Achilles calls for Suri to save him. [[GoodAllAlong Suriyawong]] just gives him [[NeverBringAKnifeToAGunFight a knife]] then leaves, having fulfilled his plan to betray Achilles at the very moment he needed help.
174	* [[BigBad Serpine]] is deserted by [[EnigmaticMinion the White Cleaver]] this way at the end of the first ''Literature/SkulduggeryPleasant'' book.
175	* {{Downplayed}} in ''Literature/ASongOfIceAndFire'', where the elderly Walder Frey is mocked as "The Late Lord Frey" for the fact that while he ''did'' eventually muster his troops for the war that put Robert Baratheon on the throne, he had obviously waited until the victor was clear before picking a side. The nickname is a reminder to others that he's [[TheStarscream opportunistic and disloyal]], and sure enough...
176	* ''Literature/StarTrekEnterpriseRelaunch:'' When a mysterious plague starts spreading around Sauria, allowing a fascist dictator to seize power despite blatantly being responsible, Trip tries getting Section 31 to help. They refuse, because they prefer the goodies the Federation gets out of the guy's rule.
177	* ''Literature/TheStormlightArchive'':
178	** In the ancient backstory, humanity's greatest defenders, the Knights Radiant, en masse abandoned their [[PoweredArmor Shardplate]] and [[AbsurdlySharpBlade Shardblades]] and walked away in an event called the Recreance. This sparked a still-ongoing war over the abandoned and now much less powerful Shards. In ''Literature/WordsOfRadiance'' we found out that it [[spoiler:effectively killed the spren who powered their gear and abilities, since they were bonded to the Radiants by the strength of the Knights' oaths.]]
179	** In ''Literature/{{The Way Of Kings\|2010}}'', [[spoiler: Highprince Sadeas]] betrays Dalinar by having his army retreat halfway though a battle and take their bridges with them, stranding Dalinar's army on a plateau with a swarm of Parshendi reinforcements on the way.
180	* In ''Literature/TheStateCounsellor'', Literature/ErastFandorin seems to make a deal with the BigBad, where they both agree to not interfere with each other. However, Fandorin knows something that could save the villain's life and, by not revealing it to him, betrays their deal and has him killed indirectly.
181	* In the second ''Literature/WarriorCats'' novel, Fireheart's suspicions about Tigerclaw being a traitor are confirmed when, during a battle, Fireheart is pinned down by Leopardfur, who is trying to kill him. He calls to Tigerclaw for help, but Tigerclaw ignores him and just stands there watching it happen.

184	[[folder:Live-Action TV]]
185	* In season 20 of ''Series/TheAmazingRace'', according to Art & J.J., this is what Rachel and Dave did by failing to use the U-turn in leg 8. However, they saw it as a more practical move, as Nary & Jamie were so far behind they saw the leg as a ForegoneConclusion.
186	* In ''Series/{{Babylon 5}}'', Lennier finds Sheridan trapped behind a containment door in a corridor filling with toxic smoke, but as he reaches for the switch to open it, he instead turns around and leaves, as with Sheridan dead, he would be once again the closest person to Delenn. Fortunately, he turns back and tries to rescue Sheridan. Unfortunately? Only AFTER back-up has done so.
187	** Part of Londo Mollari's long-winded revenge against his rival Lord Refa involves luring Refa into the tunnels of Narn on the promise of capturing G'kar, a notorious Narn rebel. Except that when Refa orders his troops to kill G'kar, they do nothing. G'kar activates a recorded message from Londo explaining that these soldiers are loyal to House Mollari, at which point they promptly file out of the room and leave Refa alone to be beat to death by angry Narns.
188	* In ''Series/TheBorgias'' Cesare knows that while Juan, his incompetent younger brother, is sieging a fortress in Forli, reinforcements for Forli are coming. He decides ''not'' to warn Juan, leading to him taking a humiliating defeat. Juan is very quick to accuse Cesare of this trope. (He's probably right; Cesare also knew that there ''was'' a chance of a messenger reaching Forli in time.)
189	* In the ''Series/BuffyTheVampireSlayer'' episode [[Recap/BuffyTheVampireSlayerS2E22BecomingPart2 "Becoming, Pt 2."]], though they were only temporary allies when they fought Angelus together, once Spike gets Dru back, he shrugs and leaves Buffy to potentially get killed by Angelus.
190	* Team Weston from ''Series/BurnNotice'' has pulled this, or made it appear that they pulled this, a number of times on the various [[MonsterOfTheWeek Villains of the Week]]. In one of the more notable cases, Sam and Jesse convinced a mafia lieutenant that his boss was about to kill him, befriended him, and then made him decide that he had to kill his boss first. They offered to help him with their "private army", (which they get by hiring about a dozen intimidating looking guys to stand around and... [[ShapedLikeItself look intimidating]]) and accompanied the lieutenant to confront his boss. As soon as the lieutenant announced his intentions complete with some EvilGloating about becoming the new boss, Sam, Jesse, and company all left, resulting in the mob lieutenant being stuck by himself with his pissed off boss and the boss' armed bodyguards. [[BolivianArmyEnding It cuts away at the part where said lieutenant decides to go out guns blazing anyway despite facing off with at least four guys...]] and according to what Fiona says after the fact he actually ''survives'' and managed to kill his boss, although he still got shot up by the bodyguards and arrested by the police afterward.
191	* ''Series/ControlZ'': When the hacker outs Isabela as transgender, she tries to seek comfort from Pablo, the only person who ever knew about her secret. However, rather than defending her from his friends, Pablo decides to feign ignorance about this piece of information by publicly breaking up with her, much to Isabela's anger. While Pablo sort-of regrets it later on after being exposed as an unfaithful boyfriend, this doesn't really change what he did before.
192	-->'''Isabela [to Pablo]:''' You're an idiot!
193	* ''Series/GameOfThrones'':
194	** In Season 6, [[spoiler:Doran Martell's [[BodyguardBetrayal guardsmen]]]] commit treason when they stand by and allow [[spoiler:Ellaria Sand]] to kill their master under their watch.
195	** Harald Karstark commits it to Roose Bolton, when he does nothing to prevent his liege's murder by standing there in front of him and doing nothing while Ramsay kills him.

197
198	[[folder:Professional Wrestling]]
199	* A classic set-up for a FaceHeelTurn involves this. Two faces go up against two heels in a tag team match. One face gets the hell beaten out of him by the heels, then manages to create just enough of an opening to go for a tag to his partner. The face on the apron, however, doesn't reach for the tag (and may even back away from the corner to prevent a tag from happening). This betrayal costs the faces the match, and the betrayal by refusing to tag paints the traitor as a bad guy in the mind of the audience. This set-up has been used countless times in all levels of pro wrestling, but it's a classic because it's such an effective way to turn someone heel.

203	* ''Theatre/WesterosAnAmericanMusical'': Early in "Plot Development", Eddard expects Littlefinger, Varys and Renly to help him secure the throne for Stannis. Littlefinger ends up being the one to actually pull a knife out and sneak up on Eddard. Varys and Renly's response to the knife being pulled out is to simply [[ScrewThisImOuttaHere leave the stage]].

207	* In ''VideoGame/BaldursGateII'', a group of mercenary mages approaches the heroes, telling them that really don't like working for Baron Ployer, and that for a modest price they will not show up for his protection when they are going to confront him.
208	* ''VideoGame/DawnOfWar'':
209	** Sindri's last sacrifice to the Chaos gods is his master Lord Bale which he leaves when Bale is surrounded by the Blood Ravens. This is what Sindri is most remembered for (or more accurately, thanks to Bale's cry of [[SayMyName "SIIINDRIII!"]]).
210	** In ''Winter Assault'', this happens whichever faction you're fighting as in the penultimate level. Both sides consist of two factions nominally allied with each other, and whichever faction you're playing as at the end goes through the gate towards the Titan, leaving the other one fighting off orks and Chaos/humans and Eldar (though if Chaos wins, the orks turn on each other as well).
211	** In ''Dawn of War II: Chaos Rising'', Eliphas, the ObviouslyEvil TreacherousAdvisor to Araghast, allows him to die at the hands of the Blood Ravens when he refuses to open a portal. Of as fans like to say, Araghast was [[PersonAsVerb Sindri'd]] by Eliphas.
212	* In ''VideoGame/DragonAgeOrigins'', the Battle of Ostagar is planned to have King Cailan and the bulk of the army, including a vanguard of Grey Wardens, lure the darkspawn horde into a narrow chasm, at which point his general, Teyrn Loghain, would attack with a second army from the back, trapping the darkspawn between them. But when the signal comes late, Loghain simply orders a retreat and returns with his men to the capital, leaving the king, his army, and every Grey Warden with them to die at the hands of the darkspawn. There is much in universe debate as to whether or not he was actually trying to kill the king or simply save what remained of the army. He did object to the plan and the signal ''did'' come far too late to save Duncan or Cailan, but he also had several reasons to want Cailan out of the picture and seems to have been plotting before the battle anyway.
213	* In the backstory for ''VideoGame/Fallout4'', this led to the near-collapse of the Minutemen, a militia group pledged to each other's mutual defense in the post-apocalyptic New England Commonwealth. In their heyday the Minutemen were able to defend major settlements like Diamond City from a horde of Super Mutants, but then they lost their headquarters, radio tower, and General all in the same disaster. Without General Becker's leadership, the scattered settlements' Minutemen units stopped supporting each other, culminating in the Quincy Massacre, when only a single squad answered the call for help from a town threatened by an army of mercenaries - and to make matters worse, one of those Minutemen decided to defect to the enemy and helped lead an attack from an unexpected quarter. In the game proper it's possible for the player to rebuild the Minutemen into a force to be reckoned with, but doing so will require earning the trust of settlements that are leery of putting their faith in a group that failed so spectacularly.
214	* Part of Yotsuyu's backstory in ''VideoGame/FinalFantasyXIV'' involves her stepparents abusing her while her stepbrother, Asahi, stood by and did nothing while seemingly enjoying watching her suffer. Yotsuyu swore that she would kill him first among the many Domans that betrayed her and she eventually does enact her revenge on him.
215	* ''Franchise/FireEmblem'':
216	** Travant in ''VideoGame/FireEmblemGenealogyOfTheHolyWar'' went to a lot of trouble to overthrow Leonster so his own country, Thracia, will have access to their fertile lands and won't have to live as impovrished sellswords anymore... but Bloom, a duke belonging to his nominal ally Grannvale, swoops in and claims the territory first. Travant bides his time since he knows that Grannvale is too powerful to fight openly. When Seliph's liberation army drives Bloom into a retreat, Bloom frantically demands help from Thracia's dracoknights. Travant gleefully ignores his appeal and instead kicks back to watch Bloom and the rebels whale on each other so that he can push the weakened victor out of the territory he's been waiting so long to rule.
217	** The Flame Emperor in ''VideoGame/FireEmblemThreeHouses'' does this multiple times to their TeethClenchedTeamwork allies, first by leaving Kostas to be tracked down and killed by the Knights of Seiros and Byleth's class, then by leaving Kronya and Solon to the same fate. [[spoiler: This trope isn't in play if you're following the Black Eagles, as since Edelgard is a playable character the betrayal is more direct, and she can even kill these three personally.]]
218	* In ''VisualNovel/HeartOfTheWoods'', this happens to [[spoiler:Abigail]] in her backstory. She offered to take the place of her sister Helena when the latter was to be sacrificed, but Helena didn't thank or try to stop her, basically showing that she never cared for [[spoiler:Abigail]] as much as [[spoiler:Abigail]] did for her.
219	* During the final battle in ''VideoGame/MassEffect1'', this is one of your options when the Citadel Council aboard the ''Destiny Ascension'' call for help. You can be subtle about it and tell the human Alliance fleet to save their strength and numbers by focusing on [[EldritchAbomination Sovereign]], who is currently attacking the Citadel, or outright pick the "Let the Council die" option and admit what you did in the aftermath of the battle. It can be very easy to justify this option, as Shepard warns the Council throughout the game that a Reaper invasion is coming, of which Sovereign is just one of thousands. But they [[CassandraTruth completely dismiss anything]] they're told about it by you, at least until a Reaper shows up at the Citadel.
220	* In ''VideoGame/RedDeadRedemptionII'', over the course of the story, Dutch does this to John at least twice and later to Arthur, most likely because both have begun to openly question and doubt him and Dutch's increasing paranoia about a traitor in the gang. First, there is some ambiguity regarding [[spoiler: John's arrest after the Saint Denis heist]] and whether Dutch actively chose not to help John. Then, Dutch willingly leaves John [[spoiler: to rot in prison to be hanged]], deceiving himself to believe that John would be fine. Later, Dutch does not step in to help Arthur who could have been captured or killed during [[spoiler: the assault at the oil refinery]], pretending he did not see Arthur, even gaslighting Arthur when accused of abandoning him. And finally, Dutch leaves John to die after the latter was shot during the final heist and tells everyone else that John was dead.
221	* ''VideoGame/StarCraft'':
222	** Part of Mengsk's UriahGambit, when he sends Kerrigan to keep a Protoss force from destroying a hive of Zerg, which he wishes to use for his own purpose. Once the Protoss are destroyed, he immediately orders all ships to retreat, leaving Kerrigan on the ground with the Zerg and not responding to her requests for evac. It didn't turn out too well for him in the long run, due to Kerrigan not only surviving but becoming the Queen of Blades with [[RoaringRampageOfRevenge the mother of all mad-ons for Mengsk]].
223	** The intro cinematic for Brood War has a huge battlecruiser sitting there without participating in the battle against the Zerg, finally leaving under the DeathGlare of the Marine who's about to be overrun.
224	** One level ends where Stukov and Duran are guarding your flanks as you try to capture Raynor and Mengsk. At the end of the level, the capture is interrupted by a massive Zerg swarm. Stukov tells Duran to move his troops in there immediately, but Duran claims he's not seeing anything, even suggesting Stukov's sensors are off, ending the call with the usual static and "you're breaking up" as Raynor and Mensk escape. Stukov isn't fooled for a second, realizing Duran was a Zerg traitor all along.
225	* ''VideoGame/ShantaeAndThePiratesCurse'': During the climax, [[spoiler:the Pirate Master]] states that when he was attacked by the Genies, Risky Boots did nothing to stop them and took over his fleet and his men when he was defeated.
226	* ''VideoGame/TheTiamatSacrament'':
227	** King Khytiel started concentrating all of Ildria's resources into protecting the castle and keeping his daughter safe, but did nothing for the rest of his domain even as they faced bandit attacks. This caused many of his soldiers to become desperate enough to help Ry'jin overthrow him.
228	** The Great Seven eventually gave up on the war and sealed themselves away. Xandra holds them in contempt for leaving Ildrians behind to be oppressed by Ry'jin. However, they have a point in that if they stayed behind to fight, Ry'jin would probably just kill them and steal their DNA, becoming even more unstoppable.
229	* ''VideoGame/UntilDawn'': When Chris is being chased by [[spoiler:the wendigo]] in Chapter 8, [[spoiler:his love interest Ashley]] will refuse to unlock the cabin door for him if [[spoiler:he chose to shoot her during Chapter 6 (despite her begging him to do so)]], instead opting to stand still and watch him get torn apart.
230	* ''VideoGame/VampireTheMasqueradeBloodlines'': Throughout the game, [[spoiler:your boss Prince [=LaCroix=]]] tries this by [[UriahGambit ordering you into increasingly dangerous situations]] and then simply not giving you the equipment, back-up, or instructions you should need to survive. He does this because you are a political liability but killing you would be a PR nightmare, so he throws you into chaotic situations in the hopes that someone else will do it for him, but it fails because [[SurprisinglyEliteCannonFodder you keep succeeding against all odds]]. You only really piece together what he's doing when [[spoiler:he sends you to negotiate with Nines in Griffith Park, then has another agent of his start a wildfire so that the [[OurWerewolvesAreDifferent werewolf]] in the park will go berserk and rip you both to shreds.]]

234	* ''Webcomic/DarthsAndDroids:'' During Episode II, Pete is angry at Jim and Ben (but more Jim than Ben, because he always hated Ben) for leaving his character for dead in their last game. So he deliberately refuses to make a Spot Check when an assassin comes after Padmé, who is only saved when the GM suddenly reminds Ben and Annie they can sense danger with the Force.

238	* ''WesternAnimation/AvatarTheLastAirbender'':
239	** In season 2, Long Feng and Azula form an alliance to capture Aang and gain control of the Earth Kingdom, with [[InevitableMutualBetrayal neither of them having any intention to share the prize]]. However, when Long Feng orders his followers, the Dai Li, to take Azula into custody in "[[Recap/AvatarTheLastAirbenderTheCrossroadsOfDestiny The Crossroads of Destiny]]", they don't move a muscle. Azula explains that the Dai Li aren't sure who would prevail between the two of them and are waiting to see which of them is more worthy to have their loyalty. She quickly browbeats Long Feng into submission.
240	** "[[Recap/AvatarTheLastAirbenderTheAvatarAndTheFireLord The Avatar and The Fire Lord]]" shows that [[PredecessorVillain Fire Lord Sozin]] and [[SpiritAdvisor Avatar Roku]] were lifelong friends until they grew apart when Sozin revealed that [[EvilColonialist he wanted to conquer the rest of the world in order to forcibly "share" the Fire Nation's prosperity and technological advances]]. After being forbidden from doing this by Roku, the two didn't talk for many years until the volcano on Roku's home island had a sudden, titanic eruption, and Sozin, who flew there on his dragon, came to help the evacuation. When Roku was poisoned and weakened by the volcanic gas, Sozin realized that if Roku died, he could move ahead with his conquest plans after all, and promptly [[MurderByInaction left his friend to die]].
241	* In the ''WesternAnimation/BatmanTheAnimatedSeries'' episode "[[Recap/TheNewBatmanAdventuresE12OverTheEdge Over the Edge]]", after getting doused by Scarecrow's fear gas, Barbara envisions a nightmare where she was killed and Commissioner Gordon, discovering her identity as Batgirl moments before she died, furiously launches a vendetta against Batman for never being told about this.
242	* In Episode 5 of ''WesternAnimation/BlueEyeSamurai'', Akemi tries to get Mizu to prevent her father's samurai from carrying her off to go through with her ArrangedMarriage. Mizu, who is badly injured and exhausted after having won a fight against an entire {{Yakuza}} gang only minutes earlier ''and'' thinks Akemi is better off just shutting up and going along with the marriage, wearily sits down and does nothing, allowing the samurai to take Akemi away. Akemi's furious and incredulous cries echo in Mizu's ears as they ride off.
243	* ''WesternAnimation/JackieChanAdventures'': In the series finale, Jade convinces Jackie not to interfere with their current ally [[BigBad Shendu]] from confronting his son Drago alone as the latter is being dragged into the demon netherworld, causing both of them to be banished from Earth. However, since Shendu has a long history of [[ChronicBackstabbingDisorder turning on]] everyone he meets when they are no longer useful to him, this is actually a ''good'' thing.
244	* In ''WesternAnimation/SheRaAndThePrincessesOfPower'', Scorpia does nothing when Catra knocks out Entrapta with a stun baton and arranges for Entrapta's exile to Beast Island. Scorpia's guilt gnaws at her until she leaves the Horde and alerts the Princesses to Entrapta's whereabouts.
245	* ''WesternAnimation/SonicPrime'': After Sonic vanishes from touching the Red Prism Shard, Nine takes the shard for himself and abandons Rebel, Knucks, and Rusty to fend for themselves.
246	* ''WesternAnimation/SupermanTheAnimatedSeries'': In "[[Recap/SupermanTheAnimatedSeriesS1E1To3TheLastSonOfKrypton The Last Son of Krypton]]", [[IgnoredExpert Jor-El]]'s warnings of Krypton's impending doom are ignored by his people because Brainiac, acting as [[DeusEstMachina the planet's supercomputer]], presents his own findings and assures them that there is nothing wrong. Jor-El later discovers that Brainiac doctored his findings and intentionally misled the Kryptonians to buy time and save himself at their expense. In other words, an ''entire race'' had to die because of this one betrayal, and Jor-El only had enough time left to ensure that his infant son survived [[EarthShatteringKaboom Krypton's destruction]]. This makes Brainiac one of Superman's three [[ArchEnemy arch-enemies]] (the other two being Lex Luthor and Darkseid).

250	* Alexander Selkirk, the man who inspired the story of ''Literature/RobinsonCrusoe'', had a heated argument with the captain of the ship he was traveling on and said he would rather stay on an island and wait for another ship to pick him up than continue the journey with the captain. But none of the other sailors wanted to come with him, and when he was brought to the beach of an island, he got second thoughts and shouted to the boat to come back and pick him up again. They didn't. [[LaserGuidedKarma Four months later, the ship that marooned Selkirk sank]]; the Captain survived but was immediately captured by enemy soldiers and imprisoned for four years.
251	* George Clinton and Robert R. Livingston spent over a decade attacking Aaron Burr and undermining his political career, [[WithFriendsLikeThese even though he belonged to the same party as them]]. Burr believed that the party's leader, [[UsefulNotes/ThomasJefferson Thomas Jefferson]], wasn't aware of the attacks-- and didn't realize that Jefferson was in fact intentionally pulling this trope on him until Jefferson told him to his face that nobody was going to help him. [[HeroicBSoD Burr did not take it well]].
252	* The Battle of Crécy during UsefulNotes/TheHundredYearsWar counts as one if you were to ask the French King Philippe of Valois's opinion. King Philippe had hired Genoese crossbowmen as mercenaries in order to counter England's longbowmen. The Genoese would provide cover fire for the French knights, allowing them to mow down the English in a chivalric charge. However, the crossbowmen's [[DeployableCover pavise shields]] had been left behind on the baggage train, and even worse, they had been pushed out too far forward by the French advance. This, combined with water damage to their crossbows from recent rain and heavy casualties at the hands of the English, encouraged the Genoese to [[ScrewThisImOuttaHere make a tactical withdrawal]]. King Philippe, who had already lost many of his knights to the English archers during the battle as a result, saw this as outright ''betrayal''. The Count of Alençon ordered his forces to hunt down the retreating crossbowmen and slaughter them.
