[[quoteright:280:[[Webcomic/CyanideAndHappiness http://static.tvtropes.org/pmwiki/pub/images/cyanide-and-happiness_8354.jpg]]]]

Alice is dangling over a drop large enough to be certain death. The only thing holding her up is Bob, who she's attached to by the safety rope. Despite his assurances that he'll save her, she knows that the weight of the two of them is too much; she's as good as dead and if she doesn't do something, Bob will die too.

So ignoring his words, she takes out her knife, says a final goodbye and cuts her safety rope.

A common version of this is to have the characters holding hands, so that the faller must simply relax their hand to sacrifice themselves. If a character does fall in such a manner and doesn't appear onscreen as dead, [[NeverFoundTheBody they probably aren't]], except in a DwindlingParty situation.

Although the safety rope version is the most common, this trope covers any situation where someone is in such deadly danger that their death is all but assured and any rescue attempt would more than likely result in more death, making the mercy killing of the victim the pragmatic solution. A MoreHeroThanThou dispute may have preceded it, or the victim acted quickly to pre-empt the question.

Usually it's the victim who makes a HeroicSacrifice by deliberately condemning themselves to save others from death or prevent them from attempting a risky rescue attempt. The would-be rescuers are likely to feel a great deal of angst and guilt even if they did everything they could to save them.

The alternative is that it is the potential rescuer who condemns the victim to their fate. While potentially just as pragmatic as if the victim made the call, this will usually paint the character in a [[KickTheDog very negative light]], more so if they actively cause the victim's death; less so if they do so at the victim's request.

[[folder:Anime & Manga]]
* ''Anime/{{Grenadier}}'': Yajiro's love interest deliberately refuses to TakeMyHand so as not to pull him off when she's blown off a cliff in a flashback. Then it turns out that she's come back from the dead and both of them end up in virtually the exact same situation.
* Although it's not a literal rope, this is basically how ''Anime/TransformersArmada'' ends, in a rare case of it happening between enemies: Optimus Prime and Galvatron are about to be devoured by Unicron, and Optimus is the one clinging to a ledge with one and and holding Galvatron up with the other. Galvatron stabs Optimus' hand, forcing it to let go and plunging himself into Unicron; then, evidently, without Galvatron around, Unicron doesn't have enough evil to feed off of, so he disappears as well. Yes, ''Galvatron saved the universe.''
* A variation almost happens toward the end of ''Manga/FullmetalAlchemist'', when Wrath and Greed/Ling are both hanging off the edge of the Briggs fortress. Ling's devoted vassal Lan Fan is holding onto her lord, whom Wrath is trying to pull down with him. Lan Fan recently had an automail arm attached to her body and the weight is tearing it off, so Ling tries to order her to let go, but she refuses. Luckily, a Briggs soldier shoots Wrath and causes him to fall alone, enabling them to pull Ling back up before Lan Fan loses her arm entirely.
** Before that, there is a bait and switch using this trope in an earlier confrontation between the same three characters. Ling is running from Wrath while carrying an injured Lan Fan who has lost the use of her arm. Lan Fan complains that her weight will only slow him down, preventing him from escaping, but Ling doesn't want to let her go. We're then treated to a frame of Lan Fan with a resigned smile pulling out a knife and talking about how "sometimes sacrifices have to be made", followed by an off screen blood spurt. One might think she killed herself in order to convince Ling to drop her corpse, but instead we find out that [[spoiler:she actually only cut her *arm* and tied it to a dog so that the trail of blood would deceive the pursuer leading him into a dead end. They both make it alive and she later gets the aforementioned automail to replace the lost limb]].
* Subverted in ''Manga/DetectiveConan''. In the mermaid case, Kazuha falls over a cliff, but Heiji jumps after her, [[TakeMyHand grabs her with his one hand]] while [[LiteralCliffhanger holding onto a overhanging branch with his other]]. Kazuha, realizing the branch won't hold them both, takes an arrow she received as a prize recently and stabs Heiji's hand with it, in order to make him let go. [[SubvertedTrope He holds on nonetheless]], and they're both saved soon.
* A variation happens to Sabrac in ''LightNovel/ShakuganNoShana''. Bel Peol managed to latch on a chain to his arm in order to reel him in to safety after he took a nasty hit but he decides to sever his arm after realizing his (relative) impotency when compared to the Snake of the Festival, he chooses to die in the Abyss, the void between Earth and the Crimson World.
* Attempted by Seiya in SaintSeiya. When he and Shun are attacked by [[EvilTwin Dark Andromeda]] right next to a cliff, Shun is stuck between protecting the very weakened Seiya, whose survival hangs solely on how half of Shun's Armor chains are wrapped around his arm, and defending himself from [[BloodKnight Dark Andromeda's]] [[AttackAttackattack attacks.]] When Seiya realises this, [[TakeAThirdOption he decides]] to [[HeroicSacrifice cut the the chains and let himself plummet to what's surely his death]] so Shun can survive; between the [[BreakTheCutie shock of almost surely losing his friend]] and [[KickTheDog Dark Andromeda mocking them]], [[SilkhidingSteel Shun]] [[BewareTheNiceOnes snaps MASSIVELY on Dark Andromeda]] [[TheDogBitesBack and bloodily kills him]]. [[SubvertedTrope Seiya ultimately survives, but barely]].

[[folder:Comic Books]]
* ''Franchise/{{Tintin}} [[Recap/TintinTintinInTibet in Tibet]]'': Captain Haddock attempts this, but drops his pocket knife. Tharkey, who has walked out, catches up to them and makes his presence known, before saving them off-page.

[[folder:Film -- Animated]]
* A variation occurs in ''WesternAnimation/CloudyWithAChanceOfMeatballs'': In order to shut down the [=FLDSMDFR=], the heroes have to go down a long pit lined with [[ItMakesSenseInContext shards of peanut brittle]]. Since Sam is allergic to peanuts, Flint has to go alone, and he uses a licorice rope to jimmy down, with Sam feeding the rope as he goes. In the process, she gets stabbed with one of the shards, and starts to have an allergic reaction. She refuses to leave Flint, even though she'll die without her medicine, so Flint bites through the licorice and falls the rest of the way down, after telling Brent to make sure Sam gets back to the plane.
* ''WesternAnimation/PussInBoots'' has Puss dangling off the edge of a decimated stone bridge. In one hand is a rope tied around the Golden Goose, who is providing a counterweight. In the other is a rope that Humpty Dumpty is holding on to the other end of. Attacking them and San Ricardo is "The Great Terror! That's the Golden Goose's mama." The Goose's rope is starting to sever due to the stress on it from Puss and Humpty's weight rubbing it against the edge. Humpty insists that Puss save the town by delivering the Golden Goose to its mother. Puss insists that he's not going to let Humpty fall. Humpty... has other plans.
* ''Disney/BigHero6'' includes a climatic moment that messes with this trope in an interesting way. After his suit is destroyed after passing through the warp hole, Baymax sacrifices himself for Hiro by shooting Hiro back to earth through the warp hole. By effectively cutting his safety cord, Baymax sends both himself and Hiro into a fall--one to safety and one to death.
** In the manga adaptation, Tadashi and Hiro are both at the site of the portal when it malfunctions. Hiro manages to grab onto Tadashi, who, after giving his brother some parting words, willingly lets go and gets sucked into the portal.

[[folder:Film -- Live Action]]
* ''Film/VerticalLimit'': Happens to the main character's father in the prologue, causing the friction between him and his sister. All the more heartbreaking as it was the son who cut the rope at his father's insistence just moments before the sister was able to attach additional securing that might have saved them. Repeated with an IronicEcho at the end of the film when TheMentor sacrifices both himself and the SmugSnake (unwillingly) to save the others.
* ''Film/TheDayAfterTomorrow'': One of the rescue party falls through the glass roof of a snowed-over mall they were inadvertently hiking over. He cuts his rope to save the others when he sees the rest of the glass will crack before they can pull him up.
* ''Film/TouchingTheVoid'' had more or less the opposite. When trying to return to base because one of the pair had a broken leg, the other was forced to cut the rope and let them fall while attempting to lower them. Amazingly, despite thinking that his partner had certainly died from the fall, he not only survived (with even more injuries) but managed to crawl back to camp.
** It's a true story, and even more amazingly the man who did the falling (Joe Simpson) has since publicly supported the actions of the man who did the cutting (Simon Yates) and forgiven him. Simon was in an impossible position, and the cutting of the rope ultimately saved both their lives.
* In the Disney action-adventure ''Film/IronWill'' Will and his father have a dog-sledding accident on the bank of a river. With the two of them and all the dogs tangled in the sled/ropes and being dragged into the river, and Will screaming for him not to do it, the father cuts himself off the sled and drowns while the dogs drag Will and the lightened sled to safety.
* ''Film/MissionToMars'': One character takes off his helmet in space to keep his wife from wasting her fuel to come and save him as she would not have had enough to get them back.
* Played straight pretty much to the letter in ''Film/AlienResurrection''. Clone Ripley and her new TrueCompanions made up of space-smugglers are escaping from a Xenomorph in an unused elevator shaft. One smuggler, [[HandicappedBadass Vriess]], is paralysed from the waist down so his crewmate [[BlackBestFriend Christie]] strapped him to his back to get through a flooded section without leaving him behind. During the ladder climb, Christie makes the mistake of looking down... just in time for the alien to [[EyeScream spit acid into his face]]. He reflexively lets go of the ladder to claw at his melting face but Vriess catches the ladder, revealing that [[TruthInTelevision his paralysis gifted him with higher than average upper-body strength]]. Jorner eventually kills the alien with GunsAkimbo but the critter [[TakingYouWithMe grabs onto Christie's foot]], weighing down on Vriess whose arms can't support their collective weight. Christie, despite the [[OhCrap protests]] of Vriess, cuts the straps binding them together and plummets to the bottom of the shaft where he's instantly killed on impact.
* ''Film/TheGuardian'' featured this in its climax. After Ben (played by Kevin Costner) rescues Jake (played by Ashton Kutcher) on the ship in the middle of the storm, they take the safety rope up to the helicopter together. But the rope is not designed for their combined weight and begins to break.[[note]] The rescue cable on an HH-60 is designed to lift three people at once if necessary. It appeared to have been frayed some time prior [[/note]] Ben decides to sacrifice himself to save Jake. However, instead of cutting his part of the rope, he simply unstraps the glove that Jake is holding onto, falling into the water from a fatal height. Though, if the end of the movie it to be believed, Ben may be NotQuiteDead, simply AscendingToAHigherPlaneOfExistence..
* In ''Film/TheMountain'', Spencer Tracy plays a famous mountaineering guide who refuses to lead a rescue up a mountain to a crashed plane because it's simply too dangerous at that time of year. Another guide, a friend of his, agrees to lead them because they simply can't leave the survivors up there. Part of the rescue party comes back later and tells them it happened just as Tracy warned them and that his friend had sacrificed himself to save the others.
* ''Film/{{Volcano}}'':
** Two men who are rigging a condo to blow and create a lava barrier from rubble get trapped in the parking garage underneath it. When they get the radio call that the building ''has'' to be blown up right now, they lie and claim that they've gotten clear so the explosives can be set off in time.
** After evacuating the other passengers of a trapped subway train, the lead MTA official refuses to leave without the driver. After finding and carrying the unconscious man to the back of the train, he sees the only way out is to jump over a quickly spreading path of lava. Knowing he could not make the jump carrying the man, but refusing to leave him behind, the MTA official jumps as far as he can with the driver in his arms. Quickly being consumed by the lava flow he then throws the driver to the rest of the rescue party, dying and melting into the lava seconds later.
* A variation in the film ''Film/USMarshals''. As the fugitive and his girlfriend attempt to climb over a wall to escape, they quickly realize that he's unable to pull her up with him. She lets go of his hand and begs him to go, knowing full well that she'll be arrested, but giving him the chance to escape.
* ''Film/{{Gravity}}'' is about two astronauts [[DramaticSpaceDrifting cast free of their space shuttle after it is destroyed]]. They manage to make it to the International Space Station but are unable to grab hold of it. Fortunately the leg of the female protagonist tangles in a trailing line. The other astronaut knows that she's just run out of oxygen, plus there's the risk of her coming untangled as she pulls him in, so he unclips the tether holding them together.
* Inverted in ''The Eiger Sanction''. Creator/ClintEastwood's character is hung up on his own safety rope, and the only way to survive is to cut it so his friend can haul him to safety using another rope. The dilemma is [[spoiler:Eastwood has just found out his friend is TheMole. Is he planning to save him, or kill him?]]

* Averted in ''High Citadel'' by Desmond Bagley. The DirtyCoward of the team starts cutting through the rope to let the man below fall to his death, only for the lead climber to throw an axe into his head. That was a case of someone panicking rather than a ColdEquation type-decision though.
* Inverted in ''Literature/TheHeroesOfOlympus'', where instead of letting Annabeth fall by herself, Percy lets go of the ledge he was holding onto, sending them both into Tartarus.

[[folder:Live Action TV]]
* ''Series/GhostWhisperer'' had a variation in one episode, where a father allowed his wife to die (at her explicit request) in order to save their daughter. A pair of malicious manipulative ghosts who had hung around the house where they had killed someone else and then each other, were able to use the guilt of both father and daughter, to oppress and live through them.
* This is used in TheReveal of an episode of ''Series/MacGyver'': a rock star is revealed to be her [[MySiblingWillLiveThroughMe twin sister impersonating her]] after the latter died during a climbing accident and she cut the rope. This caused the surviving twin to have a FreakOut and start switching between the two identities to "keep her sister alive".
* The Doctor does a variation of this in the ''Series/DoctorWho'' episode "The Satan Pit" not to save someone's life, but to satisfy his curiosity. Fortunately, while he almost certainly fell far enough that he would have damaged or killed himself, some BenevolentPrecursors gave him a way to cushion his fall and allow him to save the day.
** Played straight by one of the Thals in "The Daleks" when he realizes Ian isn't strong enough to save him.
* ''Series/{{Mash}}'' had BJ forced to do this as the rescuer. Granted, the situation was the chopper pilot telling him he had to, they were already overloaded, and the thing they needed to rescue the wounded soldier from was a group of North Korean troops. Much angst and guilt.
** The fact that the Army gave him a medal for it didn't help. (He later gave the medal to one of the wounded soldiers.)
* In ''Series/PowerRangersLightspeedRescue,'' we have Ryan and his father holding onto something that can't support both of them. Captain Mitchell lets go. (Ryan manages to save him, though.)
* In ''Series/StargateAtlantis,'' Sheppard [[LeaveNoManBehind won't leave behind]] a [[RedShirt soldier]] who has been partially fed on by a Wraith and is in no condition to run ''or'' fight. In the end, the soldier shoots himself so Sheppard won't die protecting him.
** The same thing happened with [[InsufferableGenius McKay]] and another scientist, with whom he constantly argued. The other scientist was partially fed on by an ancient Wraith, so [=McKay=] stays behind to guard him, while Sheppard goes out to hunt for the Wraith. Realizing Sheppard needs [=McKay=]'s help and that, at best, he's looking at a short life in bed, the other scientist shoots himself, allowing [=McKay=] to go help Sheppard. While [=McKay=] doesn't do much more than distract the Wraith for a few seconds, this proves to be enough for Ford to do a GunshipRescue and blast the Wraith with a drone weapon.
* This is how Juliet from ''Series/{{Lost}}'' dies. She falls over the edge, only to be grabbed by her boyfriend Sawyer. Unfortunately, Sawyer begins to slip, so she lets go to save him.
* In the HBO film ''Deadly Voyage'', the last of the stowaways to be executed manage to escape from the murderous crew. Unfortunately, one of them has been injured. Knowing that if they stay together, they will immediately be caught and finished off, he pushes his uninjured brother away from him, wordlessly telling to make a run for it and save himself.
* ''Series/GameOfThrones''. In Season 3 the wildlings are [[CliffsOfInsanity climbing the Wall]] when a big chunk of ice falls away beneath them, leaving Tormund and Orell holding on for Jon Snow and Ygritte who are hanging from the rope which nothing to sink their axes into. Tormund refuses to let go, so Orell (who's rightly convinced that Jon Snow is a FakeDefector) saws through his rope. Jon sees what he's doing and is able to swing far enough to sink his ice-axe into a ledge just before the rope snaps.

[[folder:Video Games]]
* In ''VideoGame/PrinceOfPersiaTheSandsOfTime'', Farah is hanging over a cliff by the handle of a dagger, and the Prince is holding the blade, cutting his hand with enemies approaching-- but she knows that this will cause both of them to get killed, so she lets go and falls to her death. Fortunately, the dagger is able to rewind time... unfortunately, when the Prince tries to rewind time, it's ''out of sand''.
* In ''VideoGame/CallOfDutyGhosts'', this is what causes Rorke's StartOfDarkness. During a successful mission to assassinate the then-leader of the Federation, the helicopter he and his men are in is shot down and Rorke is left hanging on for dear life above a flooded street as Elias grabs him. In an interesting twist on how this trope normally plays out, Rorke is the one begging not to let go and Elias is forced to drop him in order to prevent them all from dying.
* In ''VideoGame/TalesFromTheBorderlands,'' [[PlayerCharacter Rhys]] and Shasha end up hanging from some partially collapsed walkways high above groud. Sasha is holding onto Rhys' legs while he tries to pull them both up, but she realizes that the structure is rapidly falling apart, and that Rhys won't be able to pull them up in time. [[HeroicSacrifice She tells him she will let go.]] [[VideoGameCaringPotential Rhys can either tell her not to,]] [[VideoGameCrueltyPotential or say he understands.]] Regardless of what you pick, [[spoiler:she lets go. Turns out that the walkway had lowered so much that they were just a few feet off the ground. She knew that, Rhys (and the player) didn't.]]

* ''Three Word Phrase'': [[http://threewordphrase.com/deathzone.htm As a result of a]] MinorInjuryOverreaction.
* Parodied in [[http://www.youtube.com/watch?v=gwvXtfRjonc this]] episode of ''Webcomic/CyanideAndHappiness''.
* The version of this where [[http://lawcomic.net/guide/?p=759 the OTHER person cuts the rope is deconstructed]] in ''Webcomic/TheIllustratedGuideToLaw'' in their section on murder. Namely? If you cut the rope on someone else... it's murder. (The law doesn't consider this self-defense.) If they cut the rope themselves, it's gonna be VERY hard to prove you didn't do it.

[[folder:Western Animation]]
* Inverted in ''WesternAnimation/AvatarTheLastAirbender'', when Sokka and Zuko break into [[TheAlcatraz Boiling Rock]]. The warden of the prison is shown early on pointedly stating that he would rather jump into the boiling lake just outside the prison than allow his escape-free reputation to be tarnished. At the climax of the episode, the good guys take the warden hostage so they can take a gondola over the aforementioned boiling lake to safety unharassed. However, the warden manages to free himself enough so that he can yell at the guards to cut the lines holding up the gondola, knowing full well that he'll be boiled alive along with the would-be escapees when it falls. The attempt is foiled, but points for trying.
* ''WesternAnimation/BewareTheBatman'': Done by Deathstroke in "Hero". In this case, he does not want to be saved by Batman, and knows that him cutting the rope and falling to his death will also cause Batman and Harvey Dent to fall because he was acting as an unwilling counterweight.
