->''"I'll tell him that the substitute Shinigami he was worried about... turned out to be a piece of trash that wasn't even worth killing."''
-->-- '''Ulquiorra Cifer''', ''Manga/{{Bleach}}''

You find yourself at the mercy of someone much more powerful than you. Whether you're too weak to keep fighting, hopelessly outclassed, or just plain out of luck, you know there's nothing you can do to stop them. And then... they do nothing. They leave you to your fate, whatever that may be, and go about their business like you were nothing but a bump in the road. What happened?

They decided that you're "Not Worth Killing."

If a hero engages in this behavior, it's usually because a hero has [[ThouShaltNotKill a code against killing]], and simply won't stain their hands with the blood of a bad guy, because their morals are more important to them. Sometimes, the hero believes that the villain is already suffering a FateWorseThanDeath, and [[CruelMercy killing them would be the easy way out]]. Sometimes the hero sees the villain is suffering and doesn't feel like they deserve a MercyKill. Sometimes the hero sees that the villain is no longer a physical threat and considers it beneath them to fight [[BloodKnight a weak opponent]]. Sometimes the hero decides that the villain is sufficiently punished by [[HumiliationConga being defeated]] or having their crimes [[ThePunishmentIsTheCrime backfire on them]]. Sometimes the hero decides that avenging whatever wrong the villain did [[VengeanceFeelsEmpty would just do nothing to solve their anger at them]], or that killing them would result in the hero [[IfYouKillHimYouWillBeJustLikeHim becoming no better than the villain]]. And sometimes the hero simply doesn't care about the villain's fate and lets them off with a warning. In any case, the hero decides the bad guy, from the toughest BigBad to the lowest of {{Mooks}}, simply isn't worth their time anymore. However, if the defeated bad guy is just [[EliteMooks the real villain's most powerful henchman]], the hero may believe he/she still has a chance at redemption, so the latter is spared death to think about what they're doing with his/her life, resulting in a somewhat possible HeelFaceTurn.

If a villain decides someone's not worth killing, it's usually either TheHero and their party or the averagely-skilled friends of the highly-skilled hero who survive their FinalBossPreview with the BigBad or TheDragon because the bad guy couldn't be bothered finishing them off. Whether or not this makes any sense as an excuse to keep the secondary heroes alive varies. Sometimes it's an excuse from a WorthyOpponent or NobleDemon to not engage in wanton slaughter. Sometimes the villain is trying to maintain a [[VillainWithGoodPublicity respectable image]] and doesn't want to risk getting his hands dirty. Sometimes the villain doesn't kill because [[PragmaticVillainy it wouldn't advance their goal]]. Sometimes the heroes fit into an EvilPlan of the villain that requires their survival (for the moment). Sometimes the villain figures that the would-be victim is actually [[TheMillstone a net liability to the heroes]] or a potential [[FaceHeelTurn convert to the villain's cause]]. Some consider the would-be victim [[EvenEvilHasStandards so pathetic or repulsive]] that being in their presence, even to kill them, disgusts them. In some cases, the villain just doesn't consider the victim any kind of threat that can interfere with their plans. Either way, expect this to backfire as the heroes eventually return and defeat the villain for real, [[WhyDontYouJustShootHim raising the question of why the villain did not just kill them]].

The most literal examples of the trope refuse to kill their targets for the same reason a normal person doesn't hunt down and stomp on every cockroach they see; it's just not worth the time and effort unless they're making a nuisance of themselves. This usually applies to characters arrogant enough to ''believe'' that the opponents aren't a real threat, or powerful enough to ''know'' that they aren't a threat. Savvy characters should note that those who invoke this trope can and will change their stance if the target causes enough trouble for them later.

Also sometimes used by the AntiHero as an excuse for not wiping out the {{Mooks}}. It can be parodied with words to the effect that, "I'd kill you, but the paperwork would kill ''me''."

[[folder:Anime & Manga]]
* In ''Anime/BlackLagoon'', Chaka ''desperately'' wanted to duel Revy despite being in way over his head. Fortunately for him, she was totally aware that he was not going to survive a fight against her under any circumstances and refused to engage him because she had no interest in fighting or killing an idiotic man-child. Unfortunately for him, Ginji wanted to kill him very, very much for completely valid reasons, and she was all too happy to turn Chaka over to him. [[CruelAndUnusualDeath It did not end well for Chaka.]]
* ''Manga/{{Bleach}}'':
** Subverted by Kenpachi. He decides Nnoitra is not worth killing once there's no fight left in him, and prepares to just leave him alone, hoping to fight him again some other day once he gets stronger. [[DontYouDarePityMe Nnoitra gets offended by the act of 'mercy' and charges Kenpachi]], who decides that this makes him worthy of being killed and cuts him down mid-stride.
** Ulquiorra took this line with Ichigo after their first confrontation, but later acknowledged him as someone that "needs to be eliminated" and started fighting him more seriously. Ichigo [[spoiler:turns this around with his SuperPoweredEvilSide and performs a NoHoldsBarredBeatdown on Ulquiorra]].
** In the "Burnout Inferno" chapters, Aizen [[spoiler:[[DefiedTrope Outright tells Yamomoto that he won't spare him or say "I won't kill you here" or anything]], and draws his blade to finish him off. Hilariously, on this one time that someone tries to defy the trope, [[TakingYouWithMe he gets a face full of Hadou 96 as a result.]] Of course, it barely burns Aizen's clothing and didn't kill Yamamoto either]].
** Ginjou does this to [[spoiler:Ichigo after [[TheReveal he reveals his true colors]] and [[PowerParasite steals Ichigo's Fullbring]]]].
** In fact, about half of battles in Bleach end with the winner leaving the loser alive because they're 'not worth killing'.
* In ''Literature/ACertainMagicalIndex'', the amoral psychopath Teitoku Kakine occasionally does this, because he feels it would be beneath him to waste energy on someone who is completely helpless or already dying. An example is when he is attacked by Rikou Takitsubo, whose powers are fueled by taking the drug Body Crystal, which slowly kills its users.
* In ''Anime/CodeGeass'', in the penultimate episode, [[spoiler:Diethard]] is not worth Geassing.
* ''Manga/DeathNote'': [[VillainProtagonist Light]] doesn't really target the regular Joes in the task force, figuring that they can be hoodwinked easily enough and besides, [[EvenEvilHasStandards they're decent enough people.]] The fact that his father is a part of said task force probably has something to do with it, too. When [[spoiler: Aizawa catches on, though, they pretty much all have to die when Near does]].
* In ''Anime/DevilMayCryTheAnimatedSeries'', Dante encounters a demon mook named Sid, who is so weak and pathetic that Dante simply tells him to get lost instead of killing him. [[spoiler:This comes back to bite him when Sid later acquires artifacts that increase his power to be a legitimate threat.]]
* ''Literature/DidntISayToMakeMyAbilitiesAverageInTheNextLife'' has a moment where Reina wants to take revenge on an army captain who has been raiding caravans, killing traders like her father. The rest of her team stop her, saying it's not worth the guilt.
* ''Anime/DragonBallZ'':
** Goku subjects Frieza to this during their fight on Namek. He fights until Frieza is no longer a challenge, then throws that fact in his face, believing that living with the shame of being defeated by a superior fighter was [[CruelMercy a far worse punishment than simply killing him]], made worse by the fact that said superior fighter was "just a monkey." Frieza, however, isn't about to give up so easily.
** A particularly strange example occurs early in the Android Saga. Dr Gero/Android 20 has the solitary goal of eliminating Goku, for his role in destroying the Red Ribbon Army. When Goku is weakened by a heart virus, Android 19 has the opportunity to finish him off. Vegeta intervenes, and when Yamcha flies away with Goku, Dr Gero decides that Goku is suddenly not worth his time, and can be finished at a later opportunity. This is despite how his entire existence has been devoted to killing Goku for the past 20-odd years. Some of this is because he wants to save the best for last and he truly believes Android 19 overpowered Goku, not knowing he only won because Goku had fallen ill.
** Cell, upon reaching his Perfect form, lays an effortless beatdown on Vegeta (who was way too powerful for him in his previous form) and then defeats Trunks only after humiliating him, then abashing him about his poor judgement in powering up too much to move fast. He then claims that both Super Saiyans have disappointed him and that none of the heroes are a threat to him now. This is part of why he lets Vegeta and Trunks live-- the other part is his desire to fight powerful opponents, giving them more time to become stronger.
** Mr. Satan "[[NoSell fights]]" Perfect Cell and is simply backhanded a few hundred feet backwards into a mountain. He inexplicably survives (Piccolo suggests Cell didn't want to waste a single drop of energy when he was about to fight Goku).
** In ''Anime/DragonBallSuper'', Goku spares Frieza again because he isn't worth killing since he failed to master his new golden form, causing Frieza to burn himself out, [[HistoryRepeats just like the last time they fought]]. [[spoiler:This [[NiceJobBreakingItHero backfires]] on him when it turns out [[SoreLoser Frieza]] still has enough power to [[EarthShatteringKaboom blow up Earth and kill everyone on it]].]]
* In ''Literature/TheExecutionerAndHerWayOfLife'', when Manon Libelle was a child, the Executioner Flare killed her mother for being an Otherworlder but spared Manon because she hadn't inherited her mother's power. Manon always felt worthless due to people being disappointed she hadn't inherited a Pure Concept, and being told that she wasn't even worth killing was the final straw that pushed her into death-seeking nihilism.
* {{Invoked|Trope}} in ''Manga/FistOfTheBlueSky'' when a mook asks a mob boss and a French general about his share of the money of a drug operation and finds himself held at gunpoint by both of them. They discuss the thing and agree he's not worth the price of a single bullet... And then they shoot him anyway.
** UsefulNotes/AdolfHitler is spared by Liu Zong Wu because he thinks the tyrant is far too pathetic to deserve a good beating.
* ''Manga/FushigiYuugi'' has Miaka's [[FaceHeelTurn ex-]][[UnluckyChildhoodFriend best friend]] Yui justify (in both of Miaka's visits to Kutou, mind you) that she only wants to keep Miaka and the Suzaku Seven alive because after all, "Where's the fun in killing them right away?" [[LikeYouWouldReallyDoIt Yeah right]].
* The ''Anime/GhostInTheShellStandAloneComplex'' episode "Jungle Cruise" ultimately results in this. The suspect in question is an ex-American soldier who is terrorizing the city and with whom Batou is familiar. This is intentional on the American Empire's part, as they're trying to draw Batou into killing the soldier for them. When the two finally confront each other, Batou seems on the verge of doing this, firing his gun...but he intentionally misses, shooting the wall behind the perp instead.
--> '''Batou:''' Sorry, pal. But my war ended a long time ago!
* Weed from ''Anime/GingaDensetsuWeed'' would often spare a bad dog's life, saying that they're not worth killing and murder is wrong. A few dogs in his own pack call him out on this...especially [[BloodKnight Kyoushiro]].
** Hiro decides this with a recently beaten Kamikiri, who's been [[GroinAttack castrated brutally]], and says that he's only showing him mercy one time. Kamikiri tries to attack the Great Pyrenees once more, but...surprise, surprise! His fangs were ripped out! And it's been confirmed that he died from his wounds.
* ''Manga/HenkyouNoRoukishiBardLoen'': After [[spoiler:Kaldus's DespairEventHorizon and asking if he's going to be killed]], Bard judges his actions [[spoiler:between being NecessarilyEvil from an economic point, a SnowballLie to the prince-turned-king he had to keep, and injustice to the farmers, soldiers and Aidra who've died for his ambitions. He]] just intimidates him to return all the money and leaves.
* ''Manga/{{InuYasha}}'': When Inuyasha was controlled by his SuperpoweredEvilSide and killing bandits right, left and centre, it took [[AloofBigBrother Sesshomaru]] to bring him down. To the [[TrueCompanions gang's]] surprise, instead of killing Inuyasha, Sesshomaru merely tells them how to reverse Inuyasha's condition. When Miroku demands to know why Sesshomaru spent the entire fight holding back against Inuyasha and refusing to kill him, Sesshomaru simply responds that there's no point in killing someone who's in no condition to know even his own self. He also adds that he'll kill Inuyasha [[TheOnlyOneAllowedToDefeatYou when he's ready]]. [[IWasJustPassingThrough He never does]].
* In an episode of ''Anime/IrresponsibleCaptainTylor'', the ''Soyokaze'' enters a dimension where the ghost of a previously demoted captain (who was DrivenToSuicide) starts haunting them, attempting to drive them to insanity and despair before killing them. However, at the end, Yamamoto and Tylor start arguing with each other about responsibilities (namely, trying to dump them on the other) and in their squabble [[IgnoredEnemy they completely ignore the ghost]] who, [[TooSpicyForYogSogoth completely shocked upon seeing how pathetic and cowardly they are]], ultimately decides to leave alone and spare their lives.
* In ''Anime/KillLaKill'', Ryuko Matoi tells Nui Harime to surrender after cutting off her arms rather than take the open opportunity to finish her off. Whereas before Ryuko held a blind, murderous, vengeful rage toward Nui, she now realizes that this only allowed Nui to manipulate her and she isn't worth the emotional energy anymore. As a result, ''Nui'' becomes [[VillainousBreakdown the one filled with blind, murderous, vengeful rage]].
* ''Anime/MagicalGirlLyricalNanohaStrikers'', The Number's attack on the TSAB's Headquarters left destruction of property, wounded many troops and main characters alike, and kidnapped two secondary characters. They let no one die. This bites them hard in the end when the wounded main characters were the turning point of the final battle and this is when they decided to drop the trope.
* ''Franchise/{{Gundam}}'':
** In ''Anime/MobileSuitGundamAGE'' [[spoiler:Decil]] gets bored seeing a UE mook clearly beating the Gundam Titus in episode 8 and orders the UE to retreat.
** In episode 7 of ''Anime/MobileSuitGundam00'' 2nd season, Setsuna's 00 Gundam suffered overheating issues after activating Trans-Am system in its fight against Mister Bushido despite Ian already warned him not to use it as the twin drive isn't stable yet. Mister Bushido realises the flaw in Gundam 00 & outright says that Setsuna isn't worth defeating at the moment, thus sparing him. Obviously, this irritates Mr Bushido's teammates.
* Inverted in ''Literature/MoribitoGuardianOfTheSpirit'' despite trying to kill her. They [[EvilCannotComprehendGood suspect this trope is why they were left alive]], [[spoiler:and in the show's climax corner Balsa to demand an answer, because their warrior's pride won't stand for being ignored. When Balsa replies she had "no reason" beyond living by a ThouShaltNotKill creed, they realize she would have done this to ''anyone'' she fought and decide not to push for a rematch]].
* ''Manga/{{Naruto}}'':
** Part of Sasuke's {{backstory}} is that this was why his brother spared his life alone among the extended family. [[spoiler: Or so he believed for years.]]
** Sasuke also gives this excuse for not killing the mooks he faces in his quest to kill his brother.
* Mireille says this to Altena in the last episode of ''Anime/{{Noir}}'', specifically that it's "not worth soiling a bullet" with her blood. [[spoiler:Altena then (nonfatally) shoots Mirielle in the arm and then tries again but Kirika jumps in by TakingTheBullet and then tries to pull a TakingYouWithMe by shoving them both into a volcanic vent, though Mireille manages to grab her in time while Altena plummets to her death, her final satisfied expression before she falls out of view suggesting this was [[ThanatosGambit the plan all along]].]]
* ''Manga/OnePiece'':
** Shanks didn't respond to Higuma's attempts to pick a fight because he felt there was no point in crushing somebody so much weaker than him. Only when Higuma threatens Luffy's life does Shanks change his opinion.
** Luffy and Zoro take a similar stance when they encounter Bellamy in Jaya. Not only was Bellamy so much weaker that crushing him would almost be insulting, actually fighting him would in a way imply that his ideology was worth getting upset over. Blackbeard declares Luffy won decisively by recognizing it wasn't worth fighting.
* In ''Anime/ResidentEvilDegeneration'', towards the end Angela Miller holds [[spoiler:Frederic Downing]] at gunpoint, once he's been outed as the real mastermind of the events. He shamelessly tries to beg for his life, even offering to share the profits with her. Angela scares him by pulling the trigger only to reveal the gun wasn't loaded, and says "You're too pathetic to kill!" before the police and the marines swoop in to arrest him.
* Phoenix Ikki from ''Manga/SaintSeiya'' delivers this line to Sea Dragon [[spoiler:Kanon]] at the end of the Poseidon Saga, throwing the pointlessness of his {{plan}} in his face before turning his back on him and walking away. [[spoiler:Kanon]] tries to retaliate, but fellow Marine Shogun, Siren Sorrento, confronts him after hearing the truth behind Poseidon's premature resurrection. Like Ikki, Sorrento reasons that [[spoiler:Kanon]] is so pathetic and worthless that fighting him would be a dishonor to Poseidon.
* In ''Literature/SoImASpiderSoWhat'', when Earth Dragon Araba destroyed Kumoko's he knew she was still alive due to his Detect skill but didn't kill her as she was too weak to be worth the effort. Kumoko, already traumatized by her near death, is further infuriated by this realization and becomes fixated on getting revenge.
* ''Anime/StreetFighterIITheAnimatedMovie'': Invoked by M. Bison towards Guile, during their confrontation near the end of the film. Bison doesn't even give Guile the dignity of fighting him back. Instead, he taunts Guile as he [[HopelessBossFight wastes time and energy]] trying to even land a punch before Bison drops him with one attack. Just when it seems he's about to finish Guile off, Bison adds further insult by turning his back on him and walks away laughing.
* Hal in ''Anime/{{Texhnolyze}}'' tells this to [[spoiler:Shinji]] after [[spoiler:being turned into a Shape,]] musing on his earlier promise to kill him when they next time met.
* In ''Manga/TokyoBabylon'' and ''Manga/{{X 1999}}'', Subaru, the ''protagonist'' of the former, is left alive by the Sakurazukamori because Seishirou explicitly tells him that he's not worth killing. This becomes Subaru's primary motivation in the sequel; he believes he can only be worth something to Seishirou ([[LoveMartyr who he loves]]) if Seishirou kills him. However, as it turns out, it's not that Subaru isn't worth killing - it's that [[spoiler:Seishirou wants Subaru to kill ''him'']].
* ''Anime/YuGiOh'': Before easily defeating Duke Devlin and Rebecca Hawkins in a duel, Valon decided that they weren't worthy to have their souls taken by the Orichalcos.
* ''Manga/YuYuHakusho'':
** Younger Toguro spared Suzuka, Bui, and Karasu. He said Suzuka was a pathetic and spineless coward, who was not worth killing. He made the other two serve him and join his Dark Tournament team. Averted with his brother. Elder Toguro says he will spare one of the two defeated team members that lay before him in the semi-finals. One begged for his life and was instantly killed. The other says he would rather die than do the same. Toguro says that his brother would let him live, but [[ILied he won't]] and finishes him off.
** The Ice Maidens were shocked and aghast that one of them gave birth to a boy (which meant she had contacted a male: strictly against their strict isolationist policy). Said boy ([[spoiler:Hiei]]) was cast down into Demon World proper and left to fend for himself. After some ordeals in the past, he located the sky island where they lived, seeking revenge. Ultimately, though, after seeing their cold, emotionless lives with his own eyes, he declares them to be not worth his time and leaves them to their pathetic existence.

* ''ComicBook/StarWarsDoctorAphra'': When Winloss and Noxx finally track down Aphra in Issue #30, it at first seems like they're going to finally take their revenge on her.

She decides to leave the battle and wait until Logan is better to exact her revenge.

* ''[[https://m.fanfiction.net/s/11481821/ Another Way]]'': Marquis has security camera footage of the Brockton Bay Brigade's ill-advised home break-in from after he skipped town. But rather than use it to discredit them, he merely brings out a spliced version to watch with his daughter each Christmas -- because he doesn't consider the Brigade to be a sufficient threat to need any action. (Brandish is unamused to hear about this. Marquis is amused by her reaction.)
* ''Fanfic/TheChildOfLove'': In chapter eight’s omake, the author thinks that Asuka is going to kill him after he used the words “time of the month” to describe her mood. However, Asuka says that he isn’t worth it… before kicking his groin.

They ''could'' execute her for murdering Jon Arryn and being an accessory to Baelish's plans, but she's so ''freaking'' crazy that it'd be a MercyKill more than anything else. Instead, Bronze Yohn Royce has her drugged to the gills for her own safety while taking custody of Robin Arryn and the Vale in preparation for the Others.
* ''Fanfic/RosarioVampireBrightestDarkness Act I'': In chapter 16, when Dark discovers that Kotsubo had tried to molest Mizore the previous year, he goes ballistic and gives him a NoHoldsBarredBeatdown.

While he's not persuaded by Gaston's begging, especially right after Gaston tried to kill ''him'', he had already promised Belle he would become a better person and simply tells Gaston to GetOut.

[[spoiler: As such, they all carry torches to the Simpson house, [[IllKillYou not only with the intent to kill Homer for what he did]], [[FamilyExtermination but also Marge and the kids for being related to him]]. And upon Cargill's plan to blow up Springfield with a nuclear bomb, the townspeople tried to escape, only for Homer to [[FromBadToWorse accidentally blow their chance and set the bomb's timer in half]]. Despite having another chance to kill Homer for this, the townspeople instead throw rocks at Homer to make him leave their presence, knowing that killing him won't do any good as they're all gonna die with him sooner or later.

She puts him over her knee, spanks him with the flat of her sword, and tells him to go home to his mother. He flees.
---->'''The Bride''': THIS IS WHAT YOU GET FOR FUCKING AROUND WITH YAKUZAS! GO HOME TO YOUR MOTHER!
** In ''Film/InglouriousBasterds'', SS Colonel Hans Landa orders a family of French Jews [[DownerBeginning assassinated in the beginning]]. A young girl escapes and Landa decides not to have her chased down. In a [[GenocideBackfire twist of fate]], the girl will grow up to play a part in [[AlternateHistory Hitler's assassination]].

!!By Title:
* In ''Film/BatmanAndRobin'' [[Characters/BatmanPoisonIvy Poison Ivy]] is about to {{kiss|OfDeath}} Commissioner Gordon before deciding to spare him, saying that he's way too old for her.
* In ''Film/BuffyTheVampireSlayer'', after her {{sidekick}} comes to help her out and her mentor dies in a HeroicSacrifice to save her, TheDragon is about to turn around and finish Buffy off when the BigBad says it's time to leave:
-->'''Lothos''': She is not ready yet.\\
'''Amilyn''': What? Dinner's off!?
* In ''Film/TheCrossing'', General Howe doesn't want to bother with finishing off the Continental Army in the middle of winter, so he leaves a small force of Hessians to keep an eye on them while he and his army winter in New York. [[UsefulNotes/GeorgeWashington Washington]] is incredulous, and also, insulted.
* Seen in the Creator/PeterCushing[=/=]Creator/ChristopherLee movie ''Film/HorrorExpress''. The brain-sucking alien finds the crazy monk not worth killing, and eventually the crazy monk starts worshiping the alien (which the alien finds somewhat annoying).
-->'''Crazy Monk''': Are you going to kill me?\\
'''Brainsucking Alien''': Oh, [[YourBrainWontBeMuchOfAMeal there's nothing in your head of any use]].
* At the end of the FinalBattle in the ''Film/JamesBond'' movie ''Film/{{Spectre}}'', [[spoiler:Blofeld]] is severely injured after his helicopter crashed onto the Westminster Bridge. As 007 approaches [[spoiler:Blofeld]] crawling away from the wreckage, he offers Bond the chance to FinishHim. But after some initial hesitation, Bond tosses his Walther PPK away and states he's "out of bullets", and leaves him to be arrested by [[BigGood M]]. [[spoiler:This also left [[EvilCannotComprehendGood Blofeld a bit perplexed as to why 007 chose to spare him]] despite their CainAndAbel relationship. And [[EvilCannotComprehendGood it also escapes Blofeld's mind]] in the fact that despite being a ProfessionalKiller, there [[EveryoneHasStandards are certain moral lines even Bond won't cross]], and [[HeWhoFightsMonsters while 007 may finally get his revenge, killing Blofeld won't do much]].]]
* ''Franchise/MarvelCinematicUniverse'':
** ''Film/AvengersInfinityWar:'' When Nebula tells Thanos that he should have killed her when he had the chance, Thanos taunts his least-favorite "daughter" that he didn't want to waste the spare parts.
** ''Film/CaptainMarvel2019'': Carol spares her EvilMentor, [[spoiler:Yon-Rogg]], finally seeing him as a pathetic man to whom she has nothing she needs to prove. Instead, she [[spoiler:sends him back to the Kree home planet and alert the [[GodEmperor Supreme Intelligence]] that she is coming to end the Kree's reign of terror]].
* In the first act of ''[[Film/Napoleon1927 Napoléon]]'' (1927), a Royal Navy officer aboard the ''HMS Agamemnon'' spots the ship ''Le Hasard'' making its way from UsefulNotes/{{Corsica}} to mainland UsefulNotes/{{France}}, and asks his superior if they should fire on the suspicious-looking craft. His superior replies that it's not important enough to be worth wasting ammunition. And so Captain [[EarlyBirdCameo Horatio Nelson]] can only glare at the departing ship, somehow sensing that he will have a long military rivalry with one of its passengers: future French [[TheEmperor Emperor]] UsefulNotes/NapoleonBonaparte (then a young army officer).[[note]] Unfortunately, director Abel Gance was never able to make the other five films in his planned Napoleon hexalogy, the first few of which would have continued the thread of Napoleon's rivalry with Nelson until the latter's death at Trafalgar in 1805.[[/note]]
* ''Film/NevadaSmith'' (1966). Creator/SteveMcQueenActor's character hunts down the men who murdered his parents one by one. The final villain he shoots several times non-fatally until he pleads for Smith to GetItOverWith. Smith just rides off, saying he's not worth it.
* In the ending of ''Film/OutlawKing'', [[spoiler:Robert the Bruce utterly crushes Edward II's army at the Battle of Loudon Hill, and then also defeats the boy prince in a personal confrontation. At this point Edward [[VillainousBreakdown actually has a panic-attack]], [[VomitIndiscretionShot vomits]] and cries out in terror as he crawls and stumbles away through mud and over the bodies of his slain Englishmen. The scene is clearly pathetic to Robert and the assembled Scots and none move forward to finish him off.[[note]] Had Edward actually been present at the battle - which most historians believe he was not - the Scots might have believed he wasn't worth ''killing'', but he would have been deemed too valuable as a hostage to be allowed to escape.[[/note]]]]
* When the Spanish ships sail by Barbossa's in ''Film/PiratesOfTheCaribbeanOnStrangerTides'', they don't so much as spare him a glance, even though their numbers would have easily allowed them to sink his ship. Barbossa sees this for what it is and realizes that his crew just wasted time getting ready for a fight.
* ''Franchise/{{Predator}}'':
** In ''Film/{{Predator}}'' Dutch is about to smash the mortally wounded Predator's head with a boulder but then changes his mind and apparently decides to leave the creature to die on its own. The Predator then demonstrates why following this trope can be a really bad idea, when he activates his self-destruct mechanism, and Dutch barely escapes the resulting explosion.
** In ''Film/AVPAlienVsPredator'', at one point one of the Predators has a chance to kill Charles Bishop Weyland, but instead turns away, due to Charles' terminal illness meaning that he's not a threat and thus not worth killing. Charles gets offended at being ignored (and is desperately trying to stall the creature in an effort to help two others get away) and fires a makeshift flamethrower at the Predator. The Predator then kills him, either having re-evaluated him as a legitimate threat or simply being pissed off at having been set on fire.
* Nemesis in ''Film/ResidentEvilApocalypse'' effortlessly mows down an entire squad of S.T.A.R.S while leaving the EthnicScrappy L.J. untouched. [[RoboCam We see L.J. through Nemesis's eyes]] and he's identified as "Armed Civilian. Threat: Minimal". When L.J. throws down his gun, the reading changes to "Noncombatant. Threat: None" and Nemesis walks away.
* In ''Film/SavingPrivateRyan'', the German soldier who stabs [[spoiler:Pvt. Mellish]] to death in the upstairs room finds [[NaiveNewcomer Cpl. Upham]] cowering on the stairs outside, and is apparently able to piece together that Upham was there and could've intervened but didn't out of [[DirtyCoward cowardice]], and thinks so little of him that he simply walks past the still-crying Upham and rejoins the battle.
* In most of the ''Franchise/{{Terminator}}'' films, Terminators have a habit of hijacking a vehicle, then ordering the driver to "get out". Presumably, scaring the driver out of the vehicle is less time-consuming than killing him and dumping his body outside. They'll also eagerly use non-lethal attacks if it's the fastest and most effective way to get non-targets out of their way.
* ''Literature/TheTwilightSaga'': In ''Breaking Dawn Part 1'', when Bella is feared dead, Jacob blames Edward and tells him to his face, "I won't kill you. That would be too easy. [[CruelMercy You deserve to live with this]]."
* ''Film/WarForThePlanetOfTheApes'': Caesar spends most of the film with [[ItsPersonal a personal vendetta]] against the Colonel because [[spoiler:he killed his wife and eldest son]]. When Caesar finally gets his chance near the end of the film, he finds the Colonel curled up alone in his quarters, [[DrowningMySorrows drunk out of his mind]], because [[spoiler:he's been infected and succumbed to the Simian Flu, rendering him permanently mute. Because in his mind, speech is what separates humans from animals, in the Colonel's own deranged logic, he is now less than human. When Caesar furiously holds a gun up to the Colonel's head, [[DeathSeeker he actually steadies Caesar's hand rather than try to fight back]]. Caesar realizes he's now too pathetic to kill, lets go of his quest for vengeance, and [[LeaveBehindAPistol leaves the pistol behind on the table]], forcing the Colonel to blow his own brains out instead.]]
* At the end of ''Film/{{Yojimbo}}'', the only enemy Sanjuro spares the life of in his CurbStompBattle is the son of a couple of farmers he met early on. The guy practically shits his pants, and [[IWantMyMommy pathetically calls for his mother]].
-->'''Sanjuro:''' Children shouldn't play with swords! Go home to your mother and live a long life eating gruel!

[[folder:Literature]]
* In ''Literature/{{Animorphs}}'', after Visser Three discovers that Tobias's father was a morphed Elfangor, he tries to arrange to see if Tobias responds in an interesting way, hoping to kill or infest him. Tobias, who already knew that Visser Three was in morph, instead hides behind his hawk instincts (at this point, he's a human in ShapeshifterModeLock as a hawk, morphed into himself) to resist showing any emotion and plays off like he's some street thug hoping his crazy father left him money. Visser Three is so disgusted that his WorthyOpponent has such an apparently useless offspring that he just lets Tobias waltz right on out.
* ''Literature/{{Discworld}}'': This basically saves Rincewind's life and the world in ''Literature/{{Sourcery}}'' when tries to attack the nigh-omnipotent sourcerer Coin with a half-brick in a sock. Coin is so fascinated by the idea of someone trying to use a weapon that feeble against him that he defies his father's orders to kill him.
* In ''Cibola Burn'', the fourth novel of ''Literature/TheExpanse'', [[spoiler:Murtry]] explicitly doesn't kill Amos and Fayez because both were crippled and they weren't worth either the time or the bullets to finish off.
* ''Franchise/HarryPotter'':
** In ''Literature/HarryPotterAndThePrisonerOfAzkaban'' Harry ''was'' going to kill Sirius Black, but [[ThouShallNotKill couldn't bring himself to do it]]. [[MiscarriageOfJustice Fortunately, too!]] Later in the same scene, when Remus Lupin and Sirius expose Peter Pettigrew as the ''actual'' turncoat who framed Sirius for betraying Harry's parents to Voldemort (and [[FakingTheDead for supposedly killing Peter]] in an explosion that also killed a dozen {{Muggles}}), they're about to kill Peter when Harry invokes this trope ''again'' by pointing out that [[RevengeBeforeReason revenge against such a pathetic scumbag isn't worth jeopardizing Sirius's innocence]]. In fact, [[CantKillYouStillNeedYou bringing Peter back alive to the authorities]] would not only [[ClearMyName clear Sirius's name]] but also serve as CruelMercy. [[PacifismBackfire Too bad the heroes didn't do a better job of restraining Peter on the way back to Hogwarts!]]
** In ''Literature/HarryPotterAndTheOrderOfThePhoenix'' Snape tells Crabbe to stop hurting Neville [[spoiler:[[ReverseMole without breaking character]]]] by telling him that if Neville chokes he'd have to do a lot of boring paperwork and also mention the Manslaughter offence when he went job hunting.
* ''The Last of the Untouchables'', by Oscar Fraley & Paul Robsky. Robsky tells of how he got lost after raiding a backwoods distillery, eventually running into an old hermit armed with a rifle who guides him to the correct trail. His partner goes pale when he hears this, as from Robsky's description the man was a notorious multiple murderer, who apparently thought that a rookie Prohibition agent wasn't worth bothering about.
* ''Literature/TortallUniverse'': In ''[[Literature/TrickstersDuet Trickster's Queen]]'', Vereyu kills the [[IneffectualSympatheticVillain recently-appointed spymaster]] (who's not really sympathetic, just incompetent, but you ''do'' kind of pity him). The heroine, {{A|ctionGirl}}liane [[TheSpymaster Cooper]], tells her that he was "not worth killing". Vereyu retorts that he "wasn't worth leaving alive, either." Aly remarks that that's true.
* A nation-scale example in ''Literature/TheWitchlands'' - the state of Illrya has never been conquered because of just how difficult it is to live there, making any attempt at colonizing it worth less than whatever could be gained from it.
* ''{{Literature/Wulfrik}}'': At the end of the book, Wulfrik decides not to kill Viglundr. Not that the man doesn't deserve it, but Wulfrik instead tells him that he's arranged a FalseFlagOperation wherein the men hired for Viglundr's expedition think he's responsible for leaving them stranded in the Empire, and once they find their way back north, will attack him. Those who don't will still demand compensation for their dead soldiers, meaning Viglundr won't be able to hire defenders, dooming his city and destroying the work of several generations of his line. [[spoiler:Even offering to let Wulfrik marry Hjordis gets rejected, since unbeknownst to him Wulfrik had already been forced to kill her]].

[[folder:Live-Action TV]]
* ''Series/BetterCallSaul'' has a variation, in which it's less of this and more "Not Worth Killing Quick and Painless". Gus Fring would rather make his formidable enemy Hector Salamanca suffer a slow, painful death instead of wasting ammo on a man that's too despicable for such compassion.
-->'''Gus:''' Would you care to know why I stopped you from killing Hector?\\
'''Mike:''' Like you said, it wasn't in your interest.\\
'''Gus:''' A bullet to the head would have been far too humane.
* ''Series/BuffyTheVampireSlayer'':
** In season 4's [[Recap/BuffyTheVampireSlayerS4E11Doomed "Doomed"]], Xander, during his [[BreakThemByTalking Breaking Speech]] to [[BadassDecay Spike]], remarks that he knows that he could easily kick Spike's ass as a result of his being [[RestrainingBolt chipped]], but he's so pathetic right now that he's not even worth the effort. Spike is so humiliated by this that he attempts to stake himself... [[BungledSuicide only to be thwarted by Xander and Willow's sudden entrance]] (Xander didn't want his Hawaiian T-shirt that Spike had borrowed turning to dust with him).
** Averted in [[Recap/BuffyTheVampireSlayerS5E10IntoTheWoods "Into the Woods"]]. After [[ExtremeMeleeRevenge massacring the vampire pimp's gang]], Buffy finds herself facing the vampire prostitute she earlier caught feeding on her boyfriend. She looks so pathetic that Buffy lets her go but then Buffy's DarkSide takes over, and [[WomanScorned she hurls a wooden spear into the vampire's back as she's running away]].
* Played with in ''Series/BurnNotice''. Michael Westen takes great pains not to kill anybody himself — often employing elaborate {{Plan}}s instead — because a body count would draw too much heat while he tries to clear his name. A few people are worth it, but the consequences are still generally unpleasant.
** In one episode, Nate invokes this on himself, after he pisses off some arms dealers. While at gunpoint, he points out that they'd spend all afternoon getting rid of the body, and he wasn't significant enough to be worth the trouble.
* ''[[Series/Charmed1998 Charmed]]'': After the IneffectualSympatheticVillain Stillman sisters manage to swap identities with the Halliwell sisters in [[Recap/CharmedS6E4ThePowerOfThreeBlondes "The Power of Three Blondes"]], they find that the Halliwells' [[GreatBigBookOfEverything Book of Shadows]] does have an entry about them. A small one. Which calls them "not worth vanquishing".
* ''Series/CriminalMinds'': The episode "Painless" centers around the anniversary of a school shooting, where survivors are being killed off. In the initial shooting, the shooter Randy Slade asked students to look him in the eyes and then shot them when they were too afraid. When one boy ''did'' look him in the eyes, Randy declared him "not worth the bullet" [[ExactWords and then escalated to a bomb.]]
* ''{{Series/Gotham}}'': After Oswald Cobblepot realizes that the Riddler no longer has the intelligence that made him a threat, Oswald chooses not to kill him commenting that now that he’s “plain old Ed Nygma” he is no longer worthy of his attention.
* ''Series/Daredevil2015'': After Karen Page survives two attempts on her life in order to leak information about criminal activity at Union Allied to the ''New York Bulletin'', Wilson Fisk and James Wesley go to work covering their tracks. They kill off Karen's former boss, the assassin that Matt Murdock defeated in Karen's apartment, and the guard that tried to strangle Karen in jail. But with Karen herself, Fisk decides to have her spared, telling Wesley that there's no need to kill her as everything she knows is already in the papers. They instead decide to try bribing Karen into silence, which backfires as it instead motivates her into investigating Fisk. And it backfires big on Wesley, as Karen ends up killing him when he kidnaps her and attempts to blackmail her.
* ''Series/DoctorWho'': In [[Recap/DoctorWhoS37E10TheBattleOfRanskoorAvKolos "The Battle of Ranskoor Av Kolos"]], when Graham and Ryan have [[spoiler:Tim Shaw]] at their mercy, they both decide not to kill him, with Graham saying the trope name word-for-word.
* ''Series/GameOfThrones''. At the beginning of Season One and the end of Season Two, the White Walkers leave a single member of the Night's Watch alive, either to spread fear or as an example of this trope.
** ''Series/HouseOfTheDragon'': Rhaenys Targaryen could have prevented the SuccessionCrisis after the death of King Viserys right then and there with the whole royal family of King's Landing at the merci of her dragon Meleys, but she decided it was not her call to start the war.
* ''Series/HoratioHornblower'': Horatio tells his opponent in a duel Jack Simpson that he's "not worth the powder" after Simpson has fired prematurely, claiming it was a misfire, wounding Horatio and giving him a free shot. Simpson then begs for his life like a DirtyCoward. The minute Horatio turns his back, however, Simpson attempts to stab him InTheBack. [[spoiler: Captain Pellew can afford the powder and shoots Simpson with an exceptionally fine shot.]]
* In ''Series/NCISNewOrleans'', Pride stops a Green Beret father from taking revenge on Michelle Facheux, stating that it's not worth killing the villainess. He reluctantly buries his weapon in the dirt inches from her face instead.
* ''Series/StarTrekDeepSpaceNine''. After Gul Dukat is demoted to commanding a freighter, he gets miffed when a Klingon warbird attacking a Cardassian colony flies off without bothering to destroy his ship.
* ''Series/StarTrekVoyager'': The initial villains the Kazon were so hated that, in a later season, Seven mentions that the Borg classified them as [[TakeThatScrappy not worth assimilating]].
* In the ''Series/{{Supernatural}}'' episode "Time Is on My Side" Dean tracks down [[ClassyCatBurglar Bela]] with the intent to kill her, before announcing that she's "not worth it." Subverted with the later reveal that Dean knew [[DraggedOffToHell her number was up anyway]].
* ''Franchise/SuperSentai'' and ''Franchise/PowerRangers'' feature multiple examples of [[WorthyOpponent honourable villains]] who will let the Rangers go after beating them.
** ''Series/PowerRangersMysticForce'' has a subversion: BlackKnight Koragg vastly outclasses the heroes but keeps finding excuses to let them live ([[spoiler:due to being a BrainwashedAndCrazy version of the Red Ranger's heroic father, who does not kill innocents]]), the main one being that it's dishonorable to slay an unworthy opponent. When a Ranger confronts him, Koragg gives the standard 'unworthy opponent' speech, and the hero responds with a volley of lightning bolts. Koragg is ''completely'' unharmed, but decides anyway that the hero's worth fighting after all and proceeds to utterly mop the floor with him (he still lets him go in the end).
*** {{Downplayed}} with his original ''Series/MahouSentaiMagiranger'' counterpart Wolzard, who spares the Magiranger siblings more because [[BloodKnight he wants them to grow and become more challenging opponents]] ([[spoiler:because he's actually the team's father ReforgedIntoAMinion, and his pride in seeing them mature is causing him to act as a StealthMentor without even realising it]]).
** ''Series/JukenSentaiGekiranger'': Rio proves that [[MyKungFuIsStrongerThanYours his Juken is stronger than theirs]] by pummeling the Rangers flat, then lets them go because they are not yet worthy of being killed by him.
** ''Series/PowerRangersWildForce'': After the [[BigBad Master Org]] is defeated and [[spoiler:[[DePower loses his Org power]], reverting to being just Victor Adler]], Cole decides to spare his life out of pity towards the hateful being he had become. [[spoiler:This backfires after Victor ends up becoming a true Org and returns more powerful than ever.]]
* ''Series/TerminatorTheSarahConnorChronicles,'':
** Cromartie slaughters the FBI agents sent after him, but leaves Ellison alive in the end, apparently for this reason. As it turns out, Cromartie does this because [[spoiler: he believes Ellison will lead him to the Connors.]]
** Another Terminator leaves at least one minor character alive because, as the audience sees through the Terminator's vision, the character has a threat level of "none". [[spoiler:Then subverted when he is (apparently) killed offscreen later in the episode by the same Terminator after he unloaded a Mossberg into it, which must have upped his threat level a tad.]]
** Cameron later explicitly tells John (after being confronted with an empathy test) that Terminators are not designed to be cruel. Which makes sense; being unfeeling machines, they think logically and practically, simply following their motivations. Interpreting an action of sheer pragmatism as cruel or benevolent is something only a human would do.
* Non-fatal variant in ''Series/TheThickOfIt'' - when Ollie informs his MeanBoss Malcolm that a disgraced former MP is here to see him, Malcolm rounds on Ollie, delivering him a metaphor about how when the Queen's butler sees a cockroach in the kitchen, he steps on it and she never knows. When Malcolm does eventually go and speak to the MP, he treats him with weary contempt rather than his characteristic foul-mouthed ranting, suggesting he finds him beneath even a bollocking.
* ''Series/TheUnit'': When the members of Alpha Team eventually find out that their CO Colonel Ryan has been having an affair with Mac Gerhardt’s wife Tiffy [[note]]The viewer is made aware of this, right in the beginning of the show [[/note]], they have an impromptu “trial” in some secluded spot in the field. Standard procedure for the Unit to handle such situations is that they execute the officer who is sleeping with an operator’s wife. And Colonel Ryan is on his knees and seems ready to accept his fate. Mac even has a pistol pointed at the colonel’s forehead. But then, Jonas asks Mac if shooting the Colonel now in such a state - unarmed and on his knees - will be good for Mac’s own warrior ethos or not. Mac ultimately decides to spare the colonel, considering him too worthless and pathetic to deserve an execution.
* ''Series/TheVampireDiaries'': For much of the third season, the good guys depend heavily on Klaus not bothering to kill them, which he could do pretty much any time he wanted.
* On one episode of ''Series/{{Wings}}'', Antonio becomes a limo driver for a businessman, only to become convinced that the guy is a mobster. Antonio frantically wants to quit but is afraid he won't be allowed to walk away. His friends comfort him by pointing out that Antonio knows nothing incriminating, so he poses no threat.
-->'''Antonio:''' You're right! I'm too stupid to kill. I would be a waste of a bullet.
* ''Series/TheWire'': Omar and his shotgun arrive on a construction site owned by Stringer Bell to waste the drug kingpin. Stringer makes a run for it after Omar shoots his bodyguard, but the project manager Stringer was speaking to gets down on his knees and rather hysterically begs and cries for mercy. Omar realizes the guy is just a civilian and moves on.

[[folder:Music]]
* In the music video for "You Could Be Mine", the Terminator from ''[[Film/Terminator2JudgmenTDay T2: Judgment Day]]'' stalks Music/GunsNRoses through a concert, finally cornering them outside as they leave the building. After scanning the band members, the assessment shown on his RoboCam is: WASTE OF AMMO.
[[/folder]]

[[folder:Newspaper Comics]]
* ''ComicStrip/CalvinAndHobbes'' has a non-killing variant: Calvin is trying to fill balloons for a water fight, but keeps messing them up and splashing water on himself. By the time Hobbes arrives, Calvin is soaked from head to toe. Hobbes just says, "Gee, what's the point?" and walks away.
[[/folder]]

[[folder:Tabletop Games]]
* In ''TabletopGame/MagicTheGathering'', Sarkhan muses upon arriving in the alternate, dragon-ruled Tarkir he's created that his old enemy, Zurgo Helmsmasher (now Bellstriker) has sunk so far he's not worth the effort to kill. Ironically, the Zurgo Helmsmasher card was AwesomeButImpractical and saw no serious tournament play, while Zurgo Bellstriker's became an instant mainstay of red decks due to being a one mana 2/2.
* ''TabletopGame/{{Munchkin}}'': Several monster will not chase you if you're below a certain level, specified on the card. If you can't fight them, you automatically succeed in running away. This being ''Munchkin'', there have been cases where other players have played level up cards on the active player specifically to raise them to the cut-off limit just to avoid this.
* In TabletopGame/{{Traveller}} ''Intersteller Wars'' the Vilani don't bother making a real effort to subjugate the Terrans because they are "just another barbarian tribe". By the time they learn differently, it is the Vilani who are being subjugated.
* ''TabletopGame/{{Warhammer 40000}}'':
** [[PlayingWithATrope Played with]] on the Imperium's general policy towards the [[SpaceElves Craftworld Eldar]] and [[TheFederation Tau Empire]]. While the humans would love to see the foul xenos extinct and don't take incursions into their space lightly, sparing both species is a matter of [[{{realpolitik}} practical foreign policy]]: In either case, the xenos are reasonable enough they often can be dealt with through diplomacy, and difficult enough to fight as to require a major expenditure of resources that can be better spent on more implacable foes such as Chaos, orks, necrons, and tyranids (and will sometimes even ally with the humans against them). In the case of the Eldar, it helps that they're a dying race anyway (their low birthrate is compounded by the fact that sexual acts can cause them to fall to Chaos), so all the Imperium ''really'' has to do is outlast them. The Tau, on the other hand, are growing aggressively, peacefully absorbing entire species that the Imperium would have destroyed as well as stealing worlds away from the Imperium.
** Imotekh the Stormlord happen to have such policy on those he defeats. High Marshal Helbrecht punishes him, leading the force that ambushed and destroyed his flagship, while Imotekh was forced to flee.
** From the novel [[Literature/IronWarriors Storm of Iron]], after the first battle of the siege, Iron Warriors Captain [[BloodKnight Kroeger]] took one of the defeated soldiers, Imperial Guardswoman Larana Utorian, as his slave after deeming her not worthy kill, though he admitted to himself [[{{Foreshadowing}} he didn't know why]] he decided not to kill her out of hand. Unfortunately for him, her hatred for Chaos and for her comrades grew to the point when it attracted the demon residing in Kroeger's armor. [[KillAndReplace Afterwards]], "Kroeger" was uncharacteristically silent, always in full armor, and more aggressive, but in a more disciplined and refined way than his usual self, more like a seasoned fighter than the usual crazed butcher he usually was. Kroeger also murdered a company's worth of Space Marines, traitor and loyalist alike, with officers and a librarian, then disappeared into a warp portal. The real Kroeger's body was only found after the siege was over.
** Orks being genetically engineered for war, they naturally exhibit this trope. However, they also apply to their enemies, so what they thought constituted the ultimate insult was nothing more than an incredibly stupid decision for the lucky victim, [[MadeASlave except when they're not so lucky]]. The only known exception to this was when the biggest Warboss in the galaxy made spared Commissar Yarrick, [[WorthyOpponent whom the ork considers the only 'umie to fight well enough to spare him so they can fight later on]], demonstrating foresight unheard-of in an ork.
** In theory, devotees of Khorne practice this trope as their WarGod rewards valor and self-sacrifice. In practice, it's more that they'll kill defenseless civilians after anything that can fight back.

[[folder:Theatre]]
* In Noah Smith's stage version of ''Theatre/TheStrangeCaseOfDrJekyllAndMrHyde'', Hyde initially refrains from killing Utterson, saying that it would be no fun to take the life of somebody who's never ''lived''. During the final confrontation, after Utterson has tracked Hyde down and figured out his secret, Hyde says that now Utterson has tasted life and is fair game.

[[folder:Video Games]]
* In ''VideoGame/AceCombat7SkiesUnknown'', in the cutscene that plays before the second to last mission, [[spoiler: Dr. Schroeder is revealed to be a Belkan, who was sent to gather data from Mihaly to improve upon Erusea’s drone army to get revenge on Osea. After Ionela, Mihaly’s oldest granddaughter, destroys the data chip that contained the data, she stares down at Schroeder with a loaded gun, and Schroeder [[FaceDeathWithDignity fully expects]] Ionela to kill him. She instead tosses the gun to the side, as it wouldn’t make her any different from him, and calls Schroeder out on what he’s done, which convinces him to help put an end to the war]].
* The {{AI|IsACrapshoot}} in ''VideoGame/AIWarFleetCommand'' starts out regarding the player this way, occasionally harassing them but otherwise leaving them alone. Much of the game is making sure the AI ''continues'' to believe this even as the player amasses enough power to turn the tide.
* At the end of ''VideoGame/AssassinsCreedII'', Ezio Auditore spares the life of [[BigBad Rodrigo Borgia/Pope Alexander VI]] despite the latter being the one who had his father and brothers killed, leaving him defeated, humiliated, disillusioned and deprived of Eden artifacts.
-->'''Rodrigo:''' Get it over with then.\\
'''Ezio:''' No. Killing you won't bring my family back... I'm done.
* In ''VideoGame/BaldursGate'', when the party visits the town of Nashkel, an NPC named Noober actively engages dialog with the party, asking inane questions, interrupting other actions, and just generally being annoying. Killing a neutral NPC in the game usually affects reputation, but killing Noober does not. However, patiently cycling through all of his dialog triggers will [[spoiler:net you some decent XP, at least at that point in the game]].
* In ''VideoGame/ChronoTrigger'', this is the justification given if you decide not to fight [[spoiler:[[DiscOneFinalBoss Magus]]]] in 12,000 B.C. At this point, you have much bigger problems (namely [[spoiler:[[BigBad Lavos]]]]), and killing [[spoiler:Magus]] accomplishes absolutely nothing towards solving said bigger problems (or, as Frog points out, [[spoiler:bringing back [[TheHeroDies Crono]] or [[DeadPartner Cyrus]]]]). [[spoiler:Magus rewards you for this decision by ''[[HeelFaceTurn joining your party]]''.]]
* ''VideoGame/DawnOfWar II: Retribution'': the ork ending has Bluddflagg pull this on the Inquisitor, stealing her hat as well.
* In ''[[VideoGame/DefJamSeries Def Jam: Fight For NY]]'', the protagonist confronts [[Music/SnoopDogg Crow]] in the finale of the story campaign, absolutely livid over [[spoiler:the death of his girlfriend]]. He's just about ready to kill Crow with a gun handed to him by [[HeelFaceTurn a defecting]] [[Music/BustaRhymes Magic]], but ends up unloading the piece around the room instead, tossing it over his shoulder while quipping that he "wasn't worth it". [[spoiler:[[SubvertedTrope The protagonist ends up killing Crow anyway when Crow, in a fit of rage, tries to kill him.]]]]
* Reversed in ''VideoGame/{{Drakengard}}'s'' canonical ending: [[spoiler:Caim has defeated the BigBad and she lays crying at his feet, [[HitMeDammit begging him to kill her.]] Caim decides [[FateWorseThanDeath that would be too easy]]]].
* In ''VideoGame/TheElderScrollsArena'' the Eternal Champion is left to rot in a dungeon because his position in the Imperial Court was so low that the usurpers saw no need to bother. This was a mistake.
* Early in ''VideoGame/Fallout2'' there's an optional encounter where you run into [[AxCrazy Frank]] [[BloodKnight Horrigan]] and a couple of Enclave soldiers butchering a random family. Luckily, you're still at the "[[FromNobodyToNightmare Nobody]]" stage in your journey and well beneath Frank's notice, so he just tells you to beat it.
* ''VideoGame/FateGrandOrder'':
** In the London Singularity, Goetia shows up and effortlessly beats up the heroes, then says that they are so weak that he won't bother to kill them before leaving.
** Hera was known for being a WomanScorned who would attack her husband Zeus' lovers. However, she didn't do anything to Europa after Zeus slept with her. This was because Europa is so ditzy that she looks insane, so Hera didn't think it was worth it to attack someone not in their right mind.
* [[VideoGame/FinalFantasyIII The Onion Knight]] attempts to {{invoke|dTrope}} this trope when he and [[VideoGame/FinalFantasyVI Terra]] are faced with the mighty [[VideoGame/FinalFantasyV Exdeath]] in ''VideoGame/DissidiaFinalFantasy''. It appears to work, as Exdeath lets them go unharmed, but not without imparting some cryptic {{foreshadowing}}, implying that he may perhaps have had [[NiceJobBreakingItHero reason to]] [[UnwittingPawn do so]]...
* ''VideoGame/GodOfWarIII'' features two inverted examples:
** When he runs into Hermes, Kratos initially holds this opinion of him, dismissing Hermes as "a fly from the ass of Zeus" that isn't worth his time. However, he reconsiders when Hermes decides to [[BullyingADragon taunt him]] over how he killed his family.
** Later, he views Hera the same, just pushing the LadyDrunk aside when she tries to pick a fight with him; however, when Hera decides to insult Pandora, Kratos loses his cool, doubles back, and [[NeckSnap snaps her neck]].
* ''VideoGame/GodOfWarPS4'': When Kratos and Atreus run into Modi after having defeated him, he is found [[IHaveNoSon completely beaten up by his own father Thor and left in disgrace]]. Kratos tells his son to leave him alone, stating this trope word-for-word as reason. However, Atreus disobeys him and [[TroublingUnchildlikeBehavior proceeds to execute Modi]] for [[YourMom insulting his mother Faye too many times]]. [[spoiler:By the end of the game, after Atreus is snapped out of his arrogance, he [[MeaningfulEcho repeats his father's advice to him]] to prevent him from strangling Baldur, and Kratos heeds his word. Too bad Baldur tries to strangle his mother Freya as soon as Kratos walks away, forcing the Spartan to step in and kill him after all.]]
* ''VideoGame/GodOfWarRagnarok'': [[spoiler: After Odin is finally defeated and Atreus has put his soul in a [[SoulJar soul marble]], neither he, Kratos, or Freya feel he's even worth the bother of smashing since he's no longer a threat. Sindri has no such compunctions.]]
* In ''VideoGame/GrandTheftAutoIV'', the main character Niko Bellic comes face to face with the man who betrayed his group in the Balkans and killed his village for money in Balkans war. The man is flown in and is in a pathetic state, barely even sane and you can choose to either execute him for crime or spare him. If the latter is chosen, Niko concludes that he is indeed not worth killing and deserves to be [[CruelMercy left alive to suffer]], while in the former case, Niko brutally kills him, only to find that VengeanceFeelsEmpty.
* In ''VideoGame/HitmanAbsolution'', after interrogating Lenny Dexter, while the player is given a variety of options to kill him (including a wacky EasterEgg option), 47 can also just drive away and let the desert take him on the basis that he's not even worth wasting a bullet on. You even gain an achievement called "Not Worth It". Besides, there's an even more fun way [[BigLippedAlligatorMoment via Ice Cream Truck]].
* In ''VideoGame/HollowKnight'', the Hunter's journal contains notes on hunting and killing most of the creatures in the game. The most prominent exception is [[BoisterousWeakling Zote]], who's ''such'' a clownishly inept jagoff that the Hunter could not even be arsed to go after him.
-->''Some rare creatures are so weak, so helpless, so inept and so irritating that hunting them gives no pleasure.''
* ''VideoGame/JediKnightIIJediOutcast'': After [[CurbStompBattle curb-stomping]] Kyle Katarn in their initial duel, [[BigBad Desann]] spares his life; not out of mercy, but because he thinks Katarn [[HowTheMightyHaveFallen has become so weak and pathetic]] after abandoning the Jedi Order that he's barely worth ''fighting'', let alone killing. [[spoiler:[[SubvertedTrope That's what he says anyways]]. The ''real'' reason he let Katarn live was so he could follow him to [[MacGuffinLocation the hidden Valley of the Jedi]], knowing that the humiliated and enraged Katarn would go there to re-empower himself in order to take on Desann.]]
* In ''VideoGame/JustCause2'', Rico bribes a low-life for information, using ([[WorthlessCurrency heavily-inflated]]) Panauan dollars. In a rare economic spin of this trope, Rico gives this quip for [[WhyDontYouJustShootHim why he didn't just shoot the informant]] [[YouHaveOutlivedYourUsefulness after he told Rico all he needed to know]]:
-->'''Rico''': Considering the value of the Panauan buck, shooting you would have been more expensive.
* In ''VideoGame/TheLastOfUsPartII'', Ellie and Abby spare each other's life on separate occasions with this in mind.
* In ''Franchise/MassEffect'', this trope is considered by the krogan race to be the ''ultimate insult'' one can give to an enemy. As a {{Proud Warrior Race|Guy}}, krogan social status is [[EnemiesEqualsGreatness determined by the enemies you make and even more so, the enemies you have killed]]. If one decides that they won't kill you, it's no act of mercy; it means you're considered less than noteworthy in a krogan's eyes while they go on to look for a better, proper enemy to kill. They extend this facet of their culture to other races as well; the long list of enemies comprising the Commander's RoguesGallery, from the already-killed to the soon-killed to the eventually-killed, is precisely why most krogan pay [[WorldsBestWarrior Shepard]] tremendous respect, despite the fact that s/he's a human.
-->'''Warlord Okeer:''' "With that, I will inflict upon the genophage the greatest insult an enemy can suffer - to be ignored."
** This trope also can appear in Garrus' loyalty mission. Garrus seeks to kill the traitor who betrayed his entire squad and caused all ten of their deaths. Once you track him down, you can help Garrus take the shot or talk to the traitor and warn him, where you learn he only did what he did because of a threat to his own life, and his life has been nothing but an empty shell of pain and guilt since. Garrus can be convinced to relent and stand down, and later says that he's okay with him living because Sidonis will have to live with that torment for the rest of his life, which he feels is a [[CallItKarma far better fate]] for him than a simple death. Later on, you can hear about how Sidonis eventually turns himself over to C-Sec out of guilt.
** In his own loyalty mission, this is Jacob's opinion of [[spoiler: [[CallingTheOldManOut his father]]]] -- that he's not worth the price of the bullet it would take to kill him (and when you consider how ammunition in ''Mass Effect'' works, that's a very low price indeed). If prompted by a renegade Shepard, Jacob will change his position to "worth shooting, [[LeaveBehindAPistol but I'm not going to do it]]".
** Finch, a member of the gang Shepard belonged in as a child. Finch attempts to blackmail Earthborn Shepard into getting a fellow gang member released from jail, using their [[StateSec Spectre]] status, but Shepard can refuse, then either scare the guy off or shoot him. If s/he shoots Finch, the C-Sec officer guarding Finch’s friend is impressed. If Finch is just told to fuck off, the C-Sec officer asks why Shepard didn’t shoot him, to which Shepard can reply that he wasn’t even worth the target practice.
** ''VideoGame/MassEffectAndromeda'' demonstrates the krogan principle with Morda. Finding one of her rivals has been trying to undermine her, she beats the crap out of him and declares him not worth killing. After that, it's shown she's gone the extra mile and not even bothered to throw him out, merely telling anyone nearby to do it for her, if they feel like it.
* ''VideoGame/MetalGear'':
** ''VideoGame/MetalGearSolidPortableOps'' has a scene where Python encounters General Skowronski in the bottom of a warehouse while hunting for Big Boss. After defeating Skowronski, Python freezes him inside a cage and exclaims "You're not worth killing!" before leaving. Snake frees the general minutes later.
** In one scene in ''VideoGame/MetalGearSolid'', Meryl tries to prove her dedication to the mission by telling Snake that if she slows him down even a little, he can shoot her. Snake tells her "[[{{Tsundere}} I don't like to waste bullets]]".
* In ''VideoGame/MiddleEarthShadowOfMordor'', Uruk captains and warchiefs with the Humiliator trait will do this upon defeating Talion. This can be a pain; Talion has ResurrectiveImmortality, and [[ImmortalLifeIsCheap there's times you'll want an Uruk to kill you]] so they can become more powerful, granting you better runes when you kill them or making them better puppets when you dominate them. The Shame mechanic lets you do this in return with a side-dish of MindRape, which will lower their level for the next time you encounter the, with the side effect of damaging them mentally on the side, starting by increasing trauma until you reduce them to a wailing, mindless EmptyShell.
* In ''VideoGame/OctopathTravelerII'', Osvald decides Stenvar isn't worth killing after his boss battle, despite the fact that Stenvar accepted a bribe from Harvey to get Osvald arrested for [[MiscarriageOfJustice a crime he didn't commit]]. Stenvar is so pathetic and greedy that Osvald sees [[LaserGuidedKarma burning all of Stenvar's money]] as a much better punishment.
* In ''Videogame/TheOuterWorlds'' if you bring Felix to the Rizzo's Secret Labs when confronted by the patrolling security robots Felix will make up an excuse so pathetic that the robots will deem your party a negligible threat and promptly ignore you.
* ''VideoGame/Persona5'':
** The Phantom Thieves feel this way towards their targets in general. Not only because they find the people they go after despicable and know that killing them would make them no better than they are, but also because it would prevent the target from having to face justice for what they've done.
** The fifth palace's guards beat Mona severely when they catch him sneaking around, but refuse to actually kill him since they don't think he's worth the time and settle for dumping him outside instead.
* ''Franchise/{{Pokemon}}'': Tyrannitar are perpetually seeking strong opponents to fight, but if they find something not worth their time, they'll just move on.
* Zest from ''VideoGame/ShiningResonance'' is a BloodKnight and SuperSoldier so desperate for a WorthyOpponent that he refuses to kill opponents he judges as "weak" because it's a waste of his time and effort. If they insist, of course, he won't hesitate to mow them down.
* Subverted in ''VideoGame/{{Silver}}''. Having destroyed the source of the titular villain's power the hero feels like sparing his life cause he's all old and pathetic now, but the Silver's Nemesis arrives and finishes him anyway. Somehow the hero has no qualms with that. Huh.
* In ''VideoGame/TheSims3'', when a Sim with both the Unlucky and Loser traits gets into a fatal accident, the Grim Reaper will appear. Instead of taking the sim to the afterlife as usual, he'll resurrect your sim. His rationale is that it would be funnier for your Sim to continue on with his miserable, pathetic life rather than being granted eternal rest.
* ''Franchise/SonicTheHedgehog'':
** In ''VideoGame/SonicAndTheBlackKnight'', after Sonic's first showdown with King Arthur, the king remarks that Sonic is "a fool of a knight not even worth slaying" before departing. This bites him in the ass later on, as Sonic takes the opportunity to [[TaughtByExperience learn and grow stronger]] in order to defeat him.
** Despite giving him more credit than he initially assessed, Infinite says Sonic isn't worth finishing after they fight in ''VideoGame/SonicForces''. Dr. Eggman, however, [[WhyDontYouJustShootHim wishes he would have gone through with it]]. In fact, [[HistoryRepeats Infinite commits the same mistake]] Shadow did [[spoiler: to him. When Shadow [[NeverSayDie destroyed]] the Jackal Squad, he defeated Infinite and let him live, telling him to "never show his face again" before leaving him to rot]].
* In ''[[VideoGame/SoulSeries SoulCalibur 2]]'', one of Raphael's {{victory quote}}s is "You're not even worth killing," said in the snootiest possible manner.
* ''VideoGame/SpookysJumpScareMansion'' originally had two endings, [[spoiler:based on how many enemies you killed with the axe. You would either be recruited as a new speciment, presumably "alive" [[WasOnceAMan in at least some manner]], or be killed and recruited as a ghostly warrior in her army. However the HD Renovation added options to disable jumpscares and specimens. If you disable ''both'', you get an EasyModeMockery ending where Spooky "congratulates" you and simply sends you on your way.]]
--> [[spoiler:'''Spooky:''' Congratulations, you've done... it. You can go home now. And if anything changes, uh, we'll... let you know. Bye.]]
* In ''Franchise/{{Starcraft}}'', one of the Zerg missions has you directing Sarah Kerrigan in an assault against Jim Raynor's headquarters on the planet Char. After razing Raynor's base to the ground Kerrigan decides not to kill him, proclaiming that he's not a threat to her....although it's possible and quite likely that she did it out of some remaining sentiment toward him. After defeating the UED base on Korhal, she decided that she had to kill both Raynor and Fenix. But after killing Fenix, she instead decided to spare Raynor again.
* ''Franchise/StreetFighter'':
** In ''VideoGame/StreetFighterII'', Guile chooses to do this to M. Bison rather than kill him in his ending. This has become a bit of CharacterizationMarchesOn as M. Bison is such a monumental world-ending threat that sparing him like this is hardly practical.
** Akuma has said this to Ryu but it's really a bluff as Akuma isn't sparing him because he regards Ryu as too pathetic to use lethal force against but rather because [[INeedYouStronger he wants a worthy challenger]] and sees Ryu becoming that once he gives into TheDarkSide. It works but not necessarily as Akuma predicted when he spared him (as Ryu never adopts Akuma's fighting philosophy to prove himself but instead proves that the opposite can be just as powerful if honed).
* In the Genocide run of ''VideoGame/{{Undertale}}'', [[spoiler:you can ditch Jerry and still qualify as genocidal. He's just that much of a pain in the ass to kill]].
* This is one of [[spoiler:Chunk's possible fates]] at the end of ''VideoGame/VampireTheMasqueradeBloodlines'', he is considered such a pathetic threat that the player can choose to convince him to stay out of the way or outright ignore him and go straight to fight the real guards.
* In the "Bad" ending route of ''VideoGame/TheWitchAndTheHundredKnight'', Metallia spared [[spoiler:Lucchini's]] life even though [[spoiler:Lucchini]] asked her to kill him, with Metallia explaining she should have the freedom to make that choice, not [[spoiler:Lucchini's]]. Metallia chose to [[spoiler:just simply sever her relationship with Lucchini]] and never want to see him again.
* In ''Videogame/TheWitcher3WildHunt'', when Geralt finally confronts the crimelord Whoreson Jr., after a solid beating and some interrogation as to Ciri's whereabouts he's given the choice of killing him or sparing him on the basis that he's not worth staining his blade. That and since [[spoiler:[[YouHaveOutlivedYourUsefulness he no longer has King Radovid's protection]] from the other crime bosses of Novigrad]] and his criminal empire has been all but dismantled means he's now powerless.
* The eponymous villain of the ''Wrath of the Lich King'' ''VideoGame/WorldOfWarcraft'' expansion. After being hyped up in the months before the release as being a villain whose threat will be felt throughout your travels instead of just "a meaningless name until you suddenly face him at the end" (the expansion is called ''The Wrath of the Lich King'', for pity's sake), every time you meet him he lets you live, either knocking you out or just giving you a stern warning, while first '''killing his minions left and right''' for their failures to kill you. He always says something like "You are barely beneath my notice" or "Perhaps in time you will become worthy of serving me." He does have ulterior motives for keeping you alive. [[spoiler: When players finally confront and almost defeat the Lich King, he uses Frostmourne to wipe out the players, and reveals his true plan; everything up to that point was a test to [[INeedYouStronger find the strongest warriors]] in Azeroth, and lure them to Icecrown where he kills them and raises them as EliteMooks in his [[NightOfTheLivingMooks undead army]].]]
** He had done it earlier in ''Warcraft III: The Frozen Throne'' as well: After severely wounding Illidan near the Frozen Throne, Arthas didn't finish him off. The game's sound files reveal that he considered Illidan a piteous creature who wasn't worth killing.
* In ''VideoGame/XMenNextDimension'', several characters use this as a taunt, including some such as Mystique saying another character isn't even worth her time. One of the first matches in the story mode could have her saying this to her [[TangledFamilyTree son]], which opens up [[ParentalAbandonment a whole set of problems]].
* Can be done at the player's discretion at the climax of the Blood Lobster sidequest in ''VideoGame/XenobladeChroniclesX''. [[spoiler:Said villain is unmasked as a bit part character you met early in the game, who went full-tilt LoonyFan after noticing all the JRPG hero tropes [[PlayerCharacter Rook]] fulfilled, and decided to become a proper villain for him. Instead of killing him (which he ''wants'' in order to finish the insane narrative in his head), Rook can just turn and walk away, which causes him a [[VillainousBreakdown total meltdown]].]]
* In ''VideoGame/XenobladeChronicles3'', after the Ouroboros breaks Colony 4's Flame Clock and liberates them from the ForeverWar, a colony member by the name of Jeremy confronts Mio and Sena about a friend of his who had been killed in battle by Agnian soldiers, not caring that they themselves were not from the same colony as said soldiers. When Mio [[PleaseKillMeIfItSatisfiesYou offers her life as compensation]], he moves to take her up on it, but relents upon seeing from her markings that [[YourDaysAreNumbered she has only a few months left to live anyway]].
* In ''VideoGame/YuGiOhCapsuleMonsterColiseum'', losing to Marik makes him declare that you suck ''so'' much you're not even worth banishing to the Shadow Realm.

[[folder:Webcomics]]
* PlayedForLaughs in ''Webcomic/EightBitTheater'' when [[BigBad Sarda]] spares the lives of [[RagtagBandOfMisfits the Dark Warriors]] because they’re so utterly incompetent and helpless that [[EvenEvilHasStandards even he can’t find the idea of killing them amusing]].
-->"Look, I don't do [[PetTheDog this]]... Uh, ever. But you guys are basically like kittens stuck on a leaking lifeboat in a typhoon. Just run."
* In ''Webcomic/BobAndGeorge'':
** [[http://www.bobandgeorge.com/archives/001223c Bob decides that killing Megaman and George would only delay his fight with Protoman]].
** Mynd decides neither of the titular characters - demigod children imbued with [[strike:fire]] explosion and electric powers, respectively - are worth killing, and even brushes George aside before trying to leave. This, inevitably, comes back to bite him in the ass.
* In ''Webcomic/GirlGenius'' Colette doesn't deem it worth her time to hunt down [[spoiler:Beausoliel's real body outside Paris after destroying all his clank bodies, as whoever his new "masters" are will certainly not be happy with [[YouHaveFailedMe his failure to deliver Paris to them]]]].
* [[FantasticRacism Dellyn Goblinslayer]] from ''Webcomic/{{Goblins}}'' [[BigBadWannabe considered himself the arch-nemesis]] of Thaco the goblin. [[spoiler:Eventually he's at the latter's mercy, thinking that Thaco is going to kill him and immortalize Dellyn as his greatest foe... [[CruelMercy only to be left alive instead]] after a truly magnificent TheReasonYouSuckSpeech.]]
--> '''Thaco:''' [[spoiler:You're not worth the XP I'd get for killing you.]]
** Of course, by recent ''TabletopGame/DungeonsAndDragons'' rules, [[spoiler:Thaco gets XP for "overcoming the challenge" that Dellyn poses, so]] he's really '''not''' worth killing at that point. But Thaco (as his name suggests) is used to the rules of older editions...
* PlayedForLaughs in [[https://www.nerfnow.com/comic/3188 this]] ''WebComic/NerfNow'' strip where Angie decides an enemy is not worth killing because they don't give out enough XP or drop valuable enough loot to be worth the effort. Said enemy is unamused.
* {{Lampshade|Hanging}}d in ''Webcomic/TheOrderOfTheStick'': During his second encounter with Roy, Xykon, the EvilOverlord, dismisses him as not worth fighting and suggests calling off the battle as a Mulligan, essentially offering Roy to go free so he can [[LevelGrinding gain power]] and return later for a "good final tussle, Hollywood style". [[spoiler: Roy rejects the offer, so Xykon kills him.]]
* ''Webcomic/TwoKinds'': Subverted in a side strip, where Zen begs for his life by saying that he is too pathetic to kill. Clovis agrees, but then replies that Zen is too pathetic to live. [[spoiler:It turns out that Clovis is playing with action figures.]]
* Seongmok from ''Webcomic/WeakHero'' is well-known for only fighting opponents that he thinks are strong. He passes up Alex without a second thought, which his partner Dongha loudly mocks Alex for. This doesn't help with Alex's existing self-doubts about being TheLoad to his best friend Ben, and he ends up picking a fight with Dongha instead to prove himself.
* ''Webcomic/ZebraGirl'': Sandra invokes this as the reason why she doesn't kill the vampires who [[spoiler:attacked Crystal and Sam]].
[[/folder]]

[[folder:Web Original]]
* PlayedForLaughs in [[https://youtu.be/chsSC8I5b3Y "A Peppa Pig Magazine"]] by ''WebVideo/{{Caddicarus}}''. Caddy tries feeding a cutout of [[WesternAnimation/PeppaPig Daddy Pig]] to his dog, Stan, only for Stan to avoid eating it and leaves it on the floor instead.
-->'''Caddicarus''': Daddy Pig, you're not even good enough for the ''DOG'' to eat.
* In ''WebVideo/CouriersMindRiseOfNewVegas,'' [[VideoGame/FalloutNewVegas The Courier]] decides Benny is not worth killing ''yet.'' When The Courier finally catches up with Benny to avenge his own attempted murder, he's stunned to disbelief by the fact that Benny not only shrugged off seeing one of his victims BackFromTheDead, [[SuicidalOverconfidence but is now offering to]] [[WeCanRuleTogether let The Courier become his right-hand man when he takes over New Vegas]]. The Courier sees right through it but lets Benny go and kills the goon squad Benny sends up to dispose of him. As The Courier puts it, he wants Benny [[OhCrap to realize how fucked he is]] before killing him, and dealing with him while he still thinks on top of things would suck all the fun out of finally killing him.
* The Dimensional Guardians from the web fiction serial ''Literature/DimensionHeroes'' find themselves being spared from death multiple times, often by the BigBad, who would much rather his servants take care of matters that are beneath him.
* In ''Roleplay/TheGamersAlliance'', [[spoiler:[[FaceHeelTurn Ronove]]]], the new [[TheDragon Dreadlord]] of the [[TheLegionsOfHell Northern Horde]], decides to spare the surviving defenders of the besieged city of Vanna and allow them to flee while the horde takes over the city. His superior and peers later question the merciful act as well as the fact that the survivors will inevitably spread the news of the horde's activities and strategies to other cities which will be prepared for the upcoming war. He quickly justifies his actions by explaining his reasons for letting the heroes flee: their worthy opponent status, the promise of a later even bloodier battle worthy of higher demons' time, as well as the heroes' tales of the siege which will weaken other cities' morale when they find out about the horde's unstoppable might. However, the Dreadlord is playing a much more complicated game because among other things he also wanted to pay the defenders back for helping him when he was helpless by letting them flee to fight another day.
* ''WebAnimation/{{RWBY}}'': At the conclusion of his battle at the end of Volume 8, James Ironwood is deliberately left alive by his opponents. [[spoiler:[[BrokenPedestal Winter Schnee]] defeats and leaves him behind in the Vault, where [[TheHeavy Cinder Fall]] later meets with [[BigBad Salem]]. Though Ironwood had believed himself to be the world's best chance to defeat Salem, she doesn't even acknowledge his existence. Cinder only acknowledges his existence fleetingly to rub in just how badly he's lost. In the end, he's left to die while Cinder and Salem fly away from the [[TrashTheSet crashing city]].]]
* In ''Literature/TheSalvationWar'' there is a psychic woman who had been mentally tormented by a demon for her entire life. After the human army conquers Hell, she finds and confronts her tormentor... who turns out to be a teenager, literally a {{Troll}} From Hell, for whom driving a random innocent person insane was just a game (well, you know the kind). She's about to shoot him, but after seeing him groveling and wetting himself with fear, she decides that he is not worth pulling the trigger.

[[folder:WesternAnimation]]
* ''WesternAnimation/AvatarTheLastAirbender'': Katara tracks down the man who [[YouKilledMyFather murdered her mother]], and after seeing what a pathetic wretch he's become since then, to the point that he's even ''begging'' her to kill his ''own'' mother in exchange, and lampshading it with a mini-TheReasonYouSuckSpeech, she lets him live with the knowledge that she will ''never'' forgive him for what he did to her and her family and that he's already living out a FateWorseThanDeath.
* ''WesternAnimation/{{Ben 10}}'':
** In one episode of the original series, after Kevin went around committing crimes and placing the blame on Ben, they end up in a showdown on a bridge. At one point, Kevin shifts back to his normal human form on accident and [[SwordOverHead is completely at Ben's mercy]], who is still using Fourarms. It seems like he's about to crush his skull with a well-placed fist or two but instead hits right next to him before walking away, remarking that Kevin's not worth it and never was. This, however, doesn't end up going well for him as he ends up needing to be saved by the guy who's been hunting him down the entire time due to Kevin's rage and hatred at being told this causing him to go OneWingedAngel. It ended up working out for the best in the long term though, as Kevin would eventually pull a HeelFaceTurn and become one of Ben's best friends.
** In the sequel series, ''WesternAnimation/Ben10AlienForce'', after getting hassled by [[TheBully school bullies]] [=JT=] and Cash, Ben is seemingly about to go alien on them... but then outright states that they aren't worth the trouble, instead opting to give them a TheReasonYouSuckSpeech about how they're nothing but sad, pathetic losers who bully others to make themselves feel big and that they need to grow up.
** ''WesternAnimation/Ben10UltimateAlien'' has JT and Cash being {{Fake Ultimate Hero}}es in "Reflected Glory". When Psyphon hears them boast about being the ones responsible for his master's defeat, [[AvengingTheVillain he arrives to Earth to destroy them]]. The two admit in tears making all this up, causing Psyphon to say the trope with disgust.
** In the sequel, ''sequel'' series ''WesternAnimation/Ben10Omniverse'', there is a less-lethal example. A group of former villains who call themselves "The Vengers" are trying to subvert Ben and become the city's superheroes instead of him. Ben not only ''doesn't'' take them seriously, but he also doesn't even bother trying to prove them wrong or compete with them. He instead chooses to sit on the sidelines and watch as they tear each other apart.
* Used in ''WesternAnimation/{{Futurama}}'', except not with killing. Zoidberg teaches Cubert that the best way to avoid an ass-kicking is to pitifully grovel at the feet of a bully. It works surprisingly well.
* ''WesternAnimation/MiraculousLadybug'' has a non-lethal variant in the [[ValentinesDayEpisodes Valentine's Day episode]]. The MonsterOfTheWeek [[FallenCupid Dark Cupid]] is infecting everyone in town with a HatePlague, but when he gets to [[AlphaBitch Chloé]], he notes that she's already so cruel and hateful that there's no point shooting her.
* ''WesternAnimation/MoralOrel'': Clay's father Arthur tells the boy he's not worth hitting following the prank that caused Clay's mother Angela to die of a heart attack. Unfortunately, this resulted in Clay associating abuse with worth and attention.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': In the episode "[[Recap/MyLittlePonyFriendshipIsMagicS4E6PowerPonies Power Ponies]]", the Mane Six and Spike are transported into Spike's comic where they become the titular heroes and Spike is their sidekick Humdrum. When they attack The Mane-iac's lair, she defeats them by paralyzing them with her [[DoomyDoomsOfDoom Hairspray Ray of Doom]]. However, she doesn't spray Spike with it, declaring that he is too "useless" to be of any concern and not worth paralyzing and taking hostage like the others. This comes back to bite her when Spike manages to infiltrate her lair and free his friends.
* ''WesternAnimation/ReBoot'': Upon defeating Megabyte, Matrix appears to be about to impale him through the skull with [=AndrAIa's=] trident... but instead stabs the space right next to Megabyte's head, declaring him to be not worth it before going on to tell Megabyte to remember the humiliation of his defeat and that [[TheGoodGuysAlwaysWin Mainframe will always endure and Megabyte will never win]]. [[spoiler:Sadly backfires come Season 4: a still-alive Megabyte invokes CameBackStrong and, because of the show's {{Cancellation}}, '''''does''''' win.]]
* ''WesternAnimation/RobotChicken'':
** The {{Yakuza}} kills all of Music/{{NSYNC}} except Joey Fatone, who was in the kitchen at the time. When he begs them not to shoot him, they tell him they wouldn't waste their bullets on a simple roadie.
** Zune Man decides to kill UsefulNotes/SteveJobs but ends up being thwarted by CD Man. After proving how outdated CD Man's format is, he takes care of him, but not before realizing how pathetic he and the Zune really are. He begs Steve Jobs to put him out of his misery, but Jobs wouldn't want to waste the bullet.
* A variation happens in ''WesternAnimation/TheVentureBros'' when Dr. Venture, Pete White, and Billy Quizboy accidentally find Sphinx's headquarters and they wipe Billy's memory of the encounter, but not Pete's. When he asks why, this is Col. Gathers' response:
-->'''Gathers:''' White, you lazy bastard, if you had even an ounce of that little guy's moxie, I'd be cleaning you like a toilet seat!

* The first time someone tried to release ''Film/TheNewYorkRipper'' in Britain, every single print got returned to Italy after the BBFC refused to classify the film.
* On ''Radio/TheHowardSternShow'' G. Gordon Liddy gave this as his reason for not holding a grudge or seeking revenge against his fellow Watergate conspirators (who had cooperated with prosecutors to get lenient sentences, leaving him hanging out to dry because he refused to do so).
* UsefulNotes/MuhammadAli once stopped a boxing match because of this. In 1972, he was having a rematch bout with Jerry Quarry. However, by the seventh round, Jerry was running on fumes and not fighting at his best. Ali saw this and urged the ref to end the bout as he could have severely injured the man.
* On a somewhat grimmer and more literal note than many of the examples here, warfare in the 21st century is often as much a contest of funding as it is technology.
** Several cases exist of military units splitting up their materiel and fighting without support because while a unit of tanks and IFV's are a delicious target for artillery, a single tank might not be worth the kind of firepower it takes to destroy it.
** Drones are cheap, mass-produceable, and present relatively small targets, meaning that to shoot one down you either need to hope it is susceptible to jamming, or you need to fire a missile at it - a missile that is often many times more expensive than the drone. Needless to say, unless that drone is spotting or attacking something critical, a missile isn't going to be used to shoot it down unless you are confident that you have enough missiles for the foreseeable future.
