A convenient way to deal with someone you want dead is to simply not save their life when a situation arises in which their death is inevitable.
Killing is messy. You have to deal with those pesky murder charges, or go to the effort of engineering a convenient "accident" or "suicide" to avert suspicion, or clean up the crime scene to hide your involvement. But as fate would have it, if your foe winds up in a fatal position and you are their only means of survival, all you have to do to kill them... is nothing at all.
In Real Life, this concept is called the duty to rescue. According to The Other Wiki, the failure to offer help for those in need isn't usually considered a crime (because of the can of worms that opens when you punish someone for "not doing anything"), but there are countries where people are obligated by the law to come to the aid of those in life peril. In France for example, abandoning a helpless person can earn you a prison sentence of up to five years. On the other hand, you cannot be prosecuted for a bad first aid, precisely for the reason to prompt people to help those in need no matter what, unless it would endanger their own lives as well. Of course, an exception is made for on-duty emergency workers, law enforcement, and military personnel, where failure to act is to violate your duty. It can also be your duty because of your relationship to the person: parents have a duty to rescue their minor children. Failing to act is also generally punishable if you're in some way responsible for creating the dangerous situation in the first place.
Compare Do with Him as You Will, Make It Look Like an Accident, Never Suicide, and Throw 'Em to the Wolves. Contrast Accidental Murder and Save the Villain. If the victim is murdered actively by a character and another character does not intervene, it's a case of Accomplice by Inaction or Betrayal by Inaction depending on the case. Contrast/Compare Failure-to-Save Murder where someone is held responsible for a death because they tried and failed to prevent it, and Bystander Syndrome when people in general don't help the victim. Is often the FaceHeel Turn for a character. Most of the time it is not a Moral Event Horizon however unless the perpetrator contributes actively enough into this to be considered indirectly culpable. This is often a favored tactic of the Technical Pacifist. Contrast Save the Jerk, where the hero might not like the person, but still goes out of their way to save them.
As a Death Trope, all spoilers will be unmarked ahead. Beware.

Usami tells Ban to use his medical knowledge and save him. Ban states that his medical skills are lacking and Usami is left to die. It's Played for Drama, though, as Ban is shown to already have been distraught over not being able to save more people during the Final Test and might not have meant malicious intent with leaving Usami.
- Dragon Ball Z: During the Frieza Saga, after Vegeta takes a mortal wound from Krillin as part of a plan to have Dende heal him and receive a Zenkai boost, Dende initially refuses to do so and is fully prepared to let Vegeta die since Vegeta was just as evil as Frieza and had killed numerous Namekians himself.

- In Fairy Tail, Loke/Leo ends up being accused of this crime. He and Aries were Celestial Spirits in the service of the cruel Karen Lilica, and to save Aries from Karen's wrath, he switched places with Aries, and gave Karen an ultimatum- he'd remain in the human world and refuse to help Karen until she canceled both their contracts. Karen was initially confident that since Leo couldn't remain in the real world forever, he'd soon be forced to give up, but he lasted longer than she expected. In the end, Karen became desperate since, without her spirits, she couldn't work as a mage, and she eventually went on a job anyway and got herself killed. The Celestial Spirit King blamed Loke for his mistress's death and banished him until Lucy successfully pleaded his case, saying that he'd only been protecting his friend Aries.

- At the very end of Now and Then, Here and There, Abelia watches while King Hamdo's palace is flooded and he drowns. In this case, it's half this trope half The Dog Bites Back since Hamdo certainly had it coming, but Abelia's face makes it clear she's still rather conflicted over it.
- In Yuureitou, this turns out to be the real way Tetsuo's adoptive mother died: she was tied to the clock tower by a killer after the treasure within, but since she'd abused Tetsuo for his transgender identity as a child (including leaving him to die in the trap-filled labyrinth beneath the tower until he pretended to cry 'like a real girl'), he simply stood and watched. Tetsuo himself makes no attempt to claim it wasn't murder, telling the cops he'd killed her and using it as a reason that Amano shouldn't be his friend.
- What primarily leads to Erya Uzruth's death in Overlord, even if Hamsuke was the one who dealt the death blow. Did he really expect his elf maidens to use their magical powers to save him when he was so clearly outmatched?

- Batman: In issue #633, Robin (Stephanie Brown) dies due to torture and Batman later discovers that Dr. Leslie Thompkins deliberately withheld treatment that could've saved her life but chose not to in order to teach the kids of Gotham a lesson about superheroing. After massive backlash, this was retconned into Thompkins making Batman think that Stephanie died when she was actually smuggled out of the country. (Then it was retconned even further into Batman and a few other adults in Stephanie's life being aware too, and everyone dancing around the Open Secret for complex psychological and political reasons...)
- The Batman story Knightfall has Jean-Paul Valley/Azrael do this while assuming Batman's identity. When the villain Abattoir is left dangling above a vat of molten steel, Jean-Paul is torn between fulfilling his duty as an avenging knight and killing him, or rejecting it and saving his life.

Even Superman pleads with her, but Kara doesn't cave in◊, and lets Brainiac disappear. Reviewed here.
- In Catwoman, Catwoman once deliberately refused to rescue Black Mask from falling to his death from a penthouse.

- The Emperor's New Groove: As Kuzco and Pacha cross a rickety old bridge on their way to the palace, Pacha falls through and ends up tangled up in the ropes.

- Frozen: Attempted by Prince Hans when he first chooses to withhold a potentially life-saving Almost Kiss from Anna, since an act of true love would save her from freezing to death from Elsa's magic (although said act is eventually done by Anna, not for Anna) then leaving her to succumb to her frozen heart. You could argue that he also sped up the process by extinguishing flames, but ultimately, it was a choice not to save, rather than to kill.

- Batman Begins: Batman uses this as a loophole around his "no killing" rule to dispose of Ra's al Ghul, who's caught on an about-to-crash train. The waters are muddied even further by the fact that he had James Gordon ride the Tumbler (a tank-esque Batmobile) and take out the bridge supports ahead of the train to cause said crash, and in that all of this was ultimately caused by Ra's, including Bruce becoming Batman in the first place since he all but orchestrated the Wayne murders in this version of the story.
Batman: I won't kill you... but I don't have to save you.

The Count (being a vampire) does not fall into the quicksand, but the priest does. As the priest sinks under the bog begging for help, the Count admits to being a vampire, shies away from the cross that the priest holds up, and then watches from a distance doing nothing as the priest disappears and drowns.

- Isaac Asimov's "Little Lost Robot": (Discussed Trope) Dr Susan Calvin immediately conceives of this danger when informed of the modifications to the NS-2 robots. Some of the models had their First Law were modified to say, approximately, "A robot may not harm a human being", which omits "...or through inaction, let a human come to harm". Dr Peter Bogert dismisses the idea that a robot with this modification can kill, and Dr Calvin then describes a robot dropping a heavy weight above a human, knowing that its quick reflexes will allow it to catch the weight in time to not harm the human; but then, having dropped the weight, it has the ability to decide not to stop the weight from killing the human.

- In the Dragonlance series this was the final step of Lord Soth's Slowly Slipping Into Evil descent. He had been tricked to believe that his second wife Isolde (who he had first gotten together with while still married to his first) was cheating on him and went to confront her when he should have been going to stop The Cataclysm. While he was doing this said Cataclysm began and caused a chandelier to fall on Isolde and their child. She begged him to save them, but he just stood by, and with her last breath Isolde cursed him.

- Discussed In Masques: the heroes are in a kind of rebel camp, and there are two nobles who are pretty useless and only cause problems. They jokingly discuss the option of feeding those nobles to a dragon (they're male and their virginity is questionable, but it may be worth a try), or let them be eaten by the undead abominations. Or just fall down a hole in the caves the rebels are hiding in. They don't do any of those things in the end, as, after all, they're still the heroes.

- House Frey learns a universal truth: don't try to really piss the neighbours off after decades of being pains, because they might just ignore you when you actually do need real help to not die of insurgency on all fronts... Since they are going to; buy popcorn to silently munch as they consider how lands and titles will be divvied up afterwards, offer heckled "advice" from the sidelines to you, offer real advice to those undermining you and/or critique the performances of the oh-so tragic Frey victims as they get killed. Right in front of them or relatives of them. Rather than, you know, help the decades-long problem family out of the Hate Sink hole they've definitely helped dig themselves.
- In Sphere, Norman decides to abandon Beth and Harry to their fate by rationalizing how much trouble they've become and how their fears have almost killed him.

- In Mapleshade's Vengeance, Mapleshade believes the deaths of her kits to be this: Frecklewish was watching to make sure Mapleshade left the territory when exiled, saw them swept into the river, and left. Frecklewish said she'd seen RiverClan warriors on the other side, and assumed that they'd be saved and she never wanted them to die; this is also what she told her own Clan. It's not clear if Frecklewish was lying or not, as we're limited to Mapleshade's POV and she was only aware of RiverClan once they pulled her out of the water.

The final insult to the driver as he's being charged is that if he'd saved the man's life, no charges would have been pressed due to the suicide note.
- ER: Dr. Greene once found himself alone in an elevator with the abusive father of children that he (Greene) had helped get removed from their father's custody, and the father had gone on a shooting rampage, intending to kill Mark's wife and daughter. The patient went into cardiac arrest, and Mark allowed him to die while setting off the defibrillator to make it seem like he was attempting to save him.
- Game of Thrones: Halfway through the first season, Viserys barges into a "whore's feast" completely drunk, and threatens to cut out his sister Daenerys's baby from her womb if Khal Drogo doesn't "give him his crown". After Drogo seemingly agrees, with Dany saying that Viserys will have "a golden crown that men shall tremble to behold", he has Viserys seized and melts his gold belt in a pot to "crown" Viserys. Viserys tries to plead with Dany, but she stands by and says nothing when Drogo returns, says, "A crown for a king!", and "crowns" Viserys by pouring the now-molten gold over his head, killing him.
- Resoundingly defied by Jim Gordon in one of the turning points of his characters and Gotham as a whole. He can just hand big-time criminal Theo Galavan over to the Penguin and let him have his way with him and never see his face again while neither witnessing anything or incriminating himself. Does he do that? No, true to himself, he determines that by violating his code of conduct as a cop he would be as guilty as the Penguin and chooses to take as always the responsibility upon him to make sure both that Theo is executed and that his torture won't be prolonged as it would surely otherwise be.
- One episode of The Guest Book has Jenna Fischer as a therapist who rents Froggy Cottage as part of an experiment. He takes an Alzheimer's patient there to see if recreating his past life will help him regain his memories. It works, but he then starts to revert to his life as a Klansman. Later, she discovers he once burned down a church and killed a black man in the process just before he starts an old pickup truck in the garage and asks her to go with him to church. When she and her assistant realize the garage is slowly filling with exhaust fumes, they leave him to gas himself.
- Law & Order: UK: In the episode "Samaritan", based on the original Law & Order episode "Manhood"note , a homophobic policeman is discovered to have essentially killed his (gay) colleague by not getting him any help when he was shot (the courtroom section of the episode is mostly based around proving he was there and deliberately didn't do anything).
- Luther: The biggest source of blackmail against Luther comes from the opening scene in the pilot when a child molester nearly falls to his death while fleeing capture. Instead of helping the molester back on his feet, Luther lets the man fall to his death.
- Medium: In one episode, a young Allison has visions about one of her friends. She sees that, by knocking on his door, she will stop him from killing himself, and many years later he will rape and murder teenage girls. So a few days later, she decides to not interrupt his suicide.
- Midsomer Murders:
- In "Death in Disguise", a death initially assumed to be natural causes turns out to be this. The victim suffered a heart attack and was calling for his medication, while the other present refused to give it to him, and stood by and watched him die.
- There's one where a snobby wine lover is tied to his lawn while the murderer is catapulting wine bottles at him. His wife is brought to the window and sees the whole thing (though the murderer remains unidentified). When she sees the bottle miss, she calls out corrections to the murderer. The next morning, the police arrive but she of course didn't see anything. Downplayed in that the wife probably couldn't have saved her husband if she'd wanted to (she was wheelchair-bound, and her wheelchair had been disabled), but she certainly had the mindset of this trope.
- "Birds of Prey": one Asshole Victim is a middle-aged man who lives with and horribly abuses his Maiden Aunts. So, when he comes home bruised after being hit by a car, one aunt realizes he's much more badly injured than he thinks, but puts him to bed and leaves him to die in his sleep.
- Monk: In "Mr. Monk Meets His Dad", Ben Glaser starts to cut Kenneth Woods' tie loose when it gets caught in a running semi engine, then stops. (The two were co-owners of the same trucking company, and had just found evidence that Ben was defrauding the company by buying used parts and pocketing the difference.) However, Ben ultimately kicks Kenneth's feet out from under him, just to be on the safe side.
- Nashville: Teddy watches as Lamar Wyatt has a heart attack. He begins to step forward to help, then stops, not even calling 911. Lamar dies.

- In the Korean Drama Who Are You?, Jang Yeon-hee's prospective mother-in-law really, really did not approve of the impending marriage between Yeon-hee and her son Park Woong-joon. So much so that when Yeon-hee goes into an asthma attack after a nasty argument with Mama Park, Mama Park holds onto Yeon-hee's asthma medication and watches her die.
- Primeval shows Oliver Leek. He is gathering an army of Future Predators and controlling them with technology from the future. Nick Cutter annihilates this technology and simply leaves Leek to the predators without helping him.
- In the first episode of the Vendetta season of Strike Back, Colonel Alexander Coltrane allows a henchman to bleed to death, having recognized him as a war criminal he clashed with when he was a lieutenant.
- An episode of The X-Files shows the wealthy owner of a settlement that terrorizes its inhabitants with a tulpa. When Agent Mulder arrests him and ties him up so he can not escape, the tulpa comes up to him. He asks his neighbors to help him. But the woman says that he now gets what he deserves and goes away with her husband.
- On Xena: Warrior Princess, this is how Xena originally killed Callisto; they tumbled down a hill, Callisto landed in quicksand and Xena simply let her sink. She got better, though. Multiple times.
- On The Walking Dead, several characters end up killed this way by being left to the walkers.
- Why Women Kill: After finding out that her husband Rob caused their daughter to be killed and lied to her about it for years in addition to cheating on her and planning to leave her, Beth Ann creates a plan to murder him and help her friend Mary be rid of her abusive husband Ralph at the same time. They make it look like Rob and Mary have been having an affair and plan to elope. A furiously jealous Ralph arrives at the house and fights Rob, gun in hand. Beth Ann throws Rob his own gun, but when he tries to shoot Ralph in self-defense, he finds it empty. Cut to the bullets stored away in Beth Anns drawer. Ralph shoots Rob, who dies, but not before Beth Ann whispers to him that she knows the role he played in their daughters death.
- In Carrie Underwood's "Blown Away" a young girl gets rid of her abusive father by taking refuge in the storm cellar (and locking the door from the inside) while hes passed out drunk and theres a tornado headed straight for the house.
She heard those sirens screaming out.
Her daddy laid there passed out on the couch.
She locked herself in the cellar,
Listened to the screaming of the wind.
Some people called it taking shelter.
She called it sweet revenge.
- Tanya Tucker's "No Man's Land" is about a young girl being raped, growing up to be a nurse, and seeing that one of her sick patients is her rapist. She denies him medical aid while he begs for mercy and leaves him to die in prison.
- A popular Urban Legend surrounds the Phil Collins song "In The Air Tonight". The legend usually involves someone watching someone else drown and being unwilling to help along with several other variations. In actuality, the song was about a divorce.
- In Eminem's "Stan", Stan refers to the above Phil Collins rumour during the third verse, relating it to his own situation: by this point, the lack of reply from his beloved hero has driven Stan to commit murder-suicide. In the sequel song, "Bad Guy", Stan's younger brother Matthew sets out to get revenge on Eminem, believing that Eminem committed this trope by way of not responding to his brother's letters.
- In Lillian Hellman's 1939 play The Little Foxes (later made into a 1941 film starring Bette Davis), Horace decides to cut his evil wife Regina out of his will, and tells her so.

- Little Shop of Horrors: Seymour tries to shoot Orin the Depraved Dentist, but can't bring himself to. Moments later, Orin gets himself high inside a mask full of nitrous oxide (laughing gas) but finds he can't get it off and begs Seymour to help him get it off (while he laughs maniacally.) Seymour just stands by and Orin suffocates.
- Batman: Arkham City:
- General consensus is that Batman kills the Joker after the events of the game. Granted, Batman was stabbed in the shoulder by the Joker, causing him to drop the only cure to the Joker's sickness, but random chatter in the post-game of City and throughout Batman: Arkham Knight make it clear that nobody sees much of a difference.
- In Arkham Knight's "Season of Infamy" DLC, it's possible for Batman to do this. The end of the League of Shadows mission sees Batman given the choice between saving a feeble Ra's al Ghul, or letting him die of old age without the Lazarus Pit. It seems throughout the mission that Batman is considering the latter option for the greater good, but is worried it will break his one rule. Alfred even asks Batman beforehand "is not saving someone really the same as taking a life?"
- Amnesia: Justine: The player character is presented with the option of doing this three times as a Secret Test of Character given to you by the title character, the Ax-Crazy Justine - who is the amnesiac Player Character.
- In Call of Duty: Modern Warfare 3, you came across a prisoner who's going to be executed by the militias, in order to maintain your low profile in a stealth mission, it is wiser to remain silent and let him die. You may try to save him but he'll immediately be killed by the militias and your cover will be blown.
- Ghost Recon: Future Soldier: The Ghost team deployed in Russia was about to take out the leader of the coup in Moscow when they were ordered by the US government to take him in alive. Ghost Leader is pissed off at this, but doesn't do anything to help the coup leader escape from being killed by an incoming train since he said "our orders were not to touch you."
- Loghain's betrayal at Ostagar in Dragon Age: Origins basically amounts to this. Instead of performing his part of the battle plan, which involves attacking the darkspawn from the rear while King Cailan, his forces, and the Grey Wardens are busy on the front lines, he sounds a retreat and returns with his forces to Denerim, leaving the King, Duncan, and everyone else to die at the hands of the darkspawn.
- Heavy Rain:
- Norman Jayden can do this if he fights the Origami Killer in the end. The alternative is to save him and then kill him.
- Shelby can also do this to Charles Kramer by not giving him his pills while he's having a heart attack.
- In Ghost Trick, when Sissel speaks to Lynne after she dies and tells her that he saw a video feed of her shooting him, Lynne comments that he could easily get back at her for it by simply leaving her dead. Sissel has no intention of doing that, however.
- Mass Effect:
- Mass Effect: The Council mocks, questions, and otherwise screws you for most of the game, even colluding with Udina to ground your ship on the Citadel. At the climax, you have the option to leave the Citadel fleet and the Destiny Ascension to be annihilated fighting the Geth fleet, allowing the Alliance to ride in and mop up the remnants and take down Sovereign. The dialogue tree option literally says, "Let the Council die!" Later, a renegade Shepard has the option to claim he/she was waiting for a chance to get rid of them all along, prompting a shocked response from Anderson and a smug response from Udina. However, this option also causes 10,000 people to die and can result in worsened relations between humanity and the other Council races.
- Mass Effect 2: In Jacob's loyalty mission you have the option to leave Acting Captain Taylor to be presumably maimed and killed by his feral crew. Why? He set his mechs on you and his crew, brainwashed several of them to be mindless guards, forced most of the crew to worship him like a god, and passed around the female crew members like sex slaves between officers. His abuses are so unacceptable his own son recommends you kill him or leave him to die.
- Mass Effect 3: The Renegade method to achieve peace between the Geth and Quarians is to tell the Quarians that you're sick of helping them out like you did in the past and that if they attack the soon-to-be-upgraded Geth, they will die and you will not stop it; they will then get the hint and abandon the attack. This option does, however, require a fair bit of preparatory choices going back as far as Mass Effect 2 to be available (as is the more Paragonic alternative to reconciling the two sides).
- In Metal Gear Solid V: The Phantom Pain, Huey Emmerich leaves his wife Dr. Strangelove to suffocate in the A.I. Pod she gets sealed into after she tries to stop him from placing their 2-year-old son in Sahelanthropus. When she realizes she's never getting out she begs him for a quick death, but he just leaves. When her corpse is found later Huey tries to claim she committed suicide, but at this point his credibility has been shot to hell by his pathological lying so no one believes him.
- In Until Dawn, this leads to a possible death for Chris. If you earlier chose not to save Ashley in the death traps or tried to shoot her with the gun, she will refuse to open the door when Chris is being chased by Wendigos and will watch him die instead.
- Persona 4:
- After Nanako's apparent death, the entire Investigation Team is so outraged at Namatame for his role in it that they seriously consider just tossing him into the TV world and leaving him to be ripped apart by the Shadows within as revenge; doing so leads to the Bad Ending. In The Animation, Yu very nearly does just that before managing to stop himself.
- When the true killer is revealed to be Tohru Adachi, he adamantly insists to the protagonists that he himself didn't kill Ms. Yamano and Saki; he merely threw them into the TV world and let the Shadows do it for him. Of course, some of them point out that since he had some idea of what would happen to them when he did so, that doesn't make much of a difference. The party later averts this trope when Adachi asks them to leave him in the TV world to die after he loses to them since they want him to pay for his crimes.
- Persona 5: Ichiryusai Madarame, representative of Vanity of the Seven Deadly Sins, lives up to his namesake when he lets a woman die so that he can steal her painting and adopt her young son Yusuke, whom Madarame uses to make paintings that he passes off as his own. When this fact comes out, Yusuke loses any reason to forgive Madarame for his sins and attacks him.
- There are a few instances where this can happen in Metro 2033. In particular, on the Frontline mission, you can find a pair of Red Line officers interrogating an apparent deserter, who tells them that he was merely investigating a rumor about a shortcut behind the Nazi line, after which they kill him anyway unless you kill them first. Letting the man die makes you lose a moral point while saving him gains you one, so there's incentive to do if you're trying to get the "good" ending. On the other hand, letting him die and then allowing the officers to walk away is preferable if you're trying not to kill anyone, which is required to get the achievement/trophy "Invisible Man" (and also gets you a moral point if you do go through the entire level without killing anyone).
- Metro: Last Light: One of the last levels in the game culminates with fighting Pavel and a bunch of communist soldiers in Red Square. After you wound Pavel and compromise his gas mask, the Little Dark One shows you his memories and then you're taken to a hellscape where the souls of the damned in the surrounding area start trying to drag Pavel in with them while he begs you for help. If you take too long getting to him or choose not to help, he dies; if you help him, he simply passes out and you replace the filter on his mask. Letting him die gets you the "Revenge" achievement/trophy, but it also practically guarantees that you'll get the "bad" ending.
- Injustice 2: Wonder Woman, Superman, and Damian all accuse Batman of this, pointing out how his adherence to Thou Shalt Not Kill enables psychopathic villains like Brainiac or the Joker to just keep on killing.
Robin: You coward! We are at war with these animals! You think you're better than him!? You let the Joker keep on killing! You couldn't save Lois, or Jason, or ANYONE!
Wonder Woman: None of us wanted this. But the Joker forced our hand. Metropolis changed the world. Now WE have to change with it!
Superman: Metropolis and Coast City are gone. How many more innocent people have to die before YOU accept that some lives need to be TAKEN?!
- In the DLC for Tomb Raider: Underworld, Lara Croft manages to take control of her doppelganger that was sent after her by Natla. Lara orders her clone to "make sure Natla suffers as long as possible" and then tells her to be independent and have free will while not taking orders from anyone anymore. Lara's clone then returns to Natla, who was wounded earlier, and is ordered to help free her from the debris. The clone simply stands there and watches with a devilish grin on her face as Natla starts to drown under the blue muck rising from the ground.
- Vampyr: The player can opt for Jonathan to do this when he finds out that Dr. Swansea was responsible for the Skal epidemic in London. Considering the latter was mortally injured, Jonathan can leave him to die because of the severity of his act, straight up drain him or turn him into a vampire as a Cruel Mercy. Keep in mind the first one keeps your "Not Even Once" run clean, but allows the district to fall into chaos, the second one gives you extra XP on top of ruining your run and the district, and the third one preserves your run, the district albeit at a huge cost of your XP, but backfires because Swansea regards his new condition as a blessing and now the district is at the hands of a vampire Mad Scientist. So basically, there is no good option.
- It's revealed late into Your Turn to Die that Keiji Shinogi refused to prevent his superior officer Megumi Sasahara from being ripped apart by chains.
- Acheron says this of the elves in Inverloch when—after it becomes clearer and clearer that elven society is isolationist, arrogant, selfish, and hypocritical—he learns that his father was killed by an elf for the offense of... being mad that the elves had reneged on their word to protect the da'kor. Lei'ella, an exiled elf who's herself pretty disgusted with them, delivers a What the Hell, Hero? for his willingness to let the entire race die (including the girl he undertook the quest for in the first place) just because the ones in charge are terrible. In the end, the elves are saved but are forced to recognize and reform their ways.
- The Order of the Stick: When the Faux Affably Evil Thieves Guild leader Bozzok is being beaten to death in front of Grubwiggler, one of the people he's extorting for protection money, he gets a very clear explanation of why no help will be forthcoming:
Grubwiggler: I'm sick of your banal little guild's petty intrigues interfering in my magical research. All I want is to be left alone, and I suspect your eventual successor will be more willing to accommodate that desire. ...Farewell, Bozzok. You were never as clever as you thought you were. [Teleports away, leaving Bozzok behind]
- Dragon Ball Z Abridged: Following the scene where Krillin has mortally wounded Vegeta (as Vegeta requested), Dende is understandably unwilling to heal him on account of his partaking in the Namekian genocide. He reluctantly does so when Piccolo points out how screwed they are without Vegeta's assistance.
- In Sword Art Online Abridged, Kirito almost does this when he comes home to find Suguha choking on a muffin, but to his own disappointment has undergone too much Character Development to go through with it.
Kirito: (thinking) This is it... this is the icing on my cake! A lifetime of physical and psychological abuse, brought to a swift and satisfying end! All I have to do... is nothing! I mean, this is just Darwinism at work! As long as I don't hand her this lifesaving juice that I am currently handing her NOOOOOOOOO!!
- In Dream's Minecraft Speedrunner VS 3 Hunters Finale Rematch, the Hunters are in the Nether fortress and Dream is chasing Sapnap, when all of a sudden Sapnap gets stuck fighting two wither skeletons while cornered. Dream just watches this happen as Sapnap begs him for help.
- Avatar: The Last Airbender:
- In a flashback showing parts of Roku's life, Sozin leaves Roku to die when the latter accidentally inhales toxic fumes from an erupting volcano, realizing with the Avatar out of the way, Sozin can proceed with his plans of world conquest unopposed.
- In the season one finale, Zuko considers doing this to Admiral Zhao when the latter is attacked by the (giant, enraged) spirit of the oceans. After a moment's consideration, he holds out a hand to save Zhao, but the admiral refuses to allow his rival to save him, and is swept away to what was presumably his death. It turns out Zhao should have taken Zuko's hand since he reappears in The Legend of Korra's second book as a wanderer in the Fog of Lost Souls for killing the Moon Spirit, which has driven him to insanity.
- Avatar Kyoshi let Chin the Conquerer fall to his death when she split her home island off from the mainland. Aang points out to her towards the end of the series that she didn't actually kill him, to which she replies that she sees no difference between letting him die and killing him because she was willing to kill him if that was what it took to stop his reign of terror.
- Kyoshis friend Yun got killed in her tie-in novel by his earthbending teacher, Jianzhu, in the same manner. Yun was believed to be the Avatar, so Jianzhu offered them both up to a spirit to see who it truly was. He chose to save Kyoshi once it was confirmed that she was the real Avatar but left Yun to be taken by the spirit, fully expecting it to kill him. Yun ambiguously Came Back Wrong at the climax, just to return the favor, a lot more directly.
- Bojack Horseman: It's eventually revealed in Season 6 that not only did Bojack wait seventeen minutes to call 911 when he discovered Sarah Lynn was dying from a heroin overdose at the planetarium in order to create an alibi for himself and make sure the police didn't discover he was the one who gave her the heroin in the first place, but that she didn't actually die until after EMS arrived and tried to save her. There's no way to know for sure whether immediately calling for help would have made a difference, but once a couple of reporters discover the incident and make it public, almost everybody, including many of Bojack's close friends and family, considers this trope to be in effect. He manages to avoid serious legal ramifications for that (the worst that happens on that front is that Sarah Lynn's parents sue him for his involvement in her death and he has to give them 5 million dollars for the settlement), but he becomes a pariah in Hollywood and among the public at large as they're all disgusted that he was willing to let somebody die to save his own ass. Even his friends (except for Mr. Peanutbutter) keep their distance from him, and Hollyhock cuts him out of her life in response to what happened.
- It is implied in The Dragon Prince that Viren acted so that Harrow get killed. Harrow was the king, and Viren was his wizard, and at the same time his only friend, or at least his oldest and closest confidant. When Harrow learns that elfish assassins want to kill him, Viren offers him to save his life with dark magic. But Harrow, who for some unknown reason does not want to have anything more to do with dark magic, reacts very gruffly. He forces Viren to kneel in front of him while humiliating, taunting, and offending him. When the elven assassins finally defeat the king's bodyguards, Viren does not move a finger to rescue Harrow. He even stops Callum from coming to the aid of the king. Later, General Amaya also accuses him of allowing the elves to kill Harrow so he can become king himself. It should be mentioned explicitly that it is unknown if Viren could have fended off the elven assassins because they were simply very good assassins. But because Harrow treated him so badly, of course, Viren did not do anything to protect him.
- In the Family Guy episode "Send in Stewie, Please," Stewie lets the preschool therapist he was talking to slowly die from a heart attack because he doesn't want his secrets getting out.
- Subverted in Green Lantern: The Animated Series. Sinestro uses something like this trope as a defense when his actions result in the in-custody death of Naraxis ("I didn't kill him, I just didn't save him"), but it's revealed to the viewer that Naraxis's death was anything but inadvertent; Sinestro actively manipulated events so that Naraxis would die, and actually gloated about it to the guy as he suffocated, making it just straight-up murder.
- Justice League:
- In "Twilight", Darkseid shows up in the Watchtower and asks for the League's help since Brainiac is attacking Apokolips. Superman, having suffered a lot at Darkseid's hands and expecting that Darkseid has an ulterior motive, only says, "Good." Superman turns out to be right.
- In "The Enemy Below", Aquaman confronts his evil brother Orm who stole the Trident of Poseidon, tried to overthrow him, and put him and his baby son near a submarine volcano to kill them both off. When Orm ends up hanging over an abyss during their last fight, he shamelessly begs Aquaman to save him. Aquaman just picks up his fallen trident while coldly saying "I believe this is mine" and lets him fall.
