9	----
10
11	* ''Series/TwentyFour'':
12	** This is often done by the villains, especially when it comes to kidnapped civilians who have useful skills that they can exploit. It ''always'' ends badly for the poor civilians.
13	** Also pulled by the heroes. Jack works with both Nina Meyers and Christopher Henderson to foil the terrorists, putting aside his desire for revenge. As soon as the terrorists are stopped or they no longer have a use, he killed them both. Both of them know him well enough to see this coming and take steps to avoid it, but [[OutGambitted both fail]]. He also pulls this one last time on Dana Walsh in the final season, but with a twist. Despite Dana being one of the villains, Jack carrying this out [[spoiler:is to actually [[TheReveal reveal]] that he ''[[WhamEpisode isn't]]'' the [[VillainProtagonist hero]] this time around]].
14	* ''Series/AdamAdamantLives'': After betraying Adam to the Face, Louise served her new master faithfully for sixty-five years. That didn't cut any [[HumanPopsicle ice]] with the Face; as soon as he was revived, he made off with his new, younger FemmeFatale sidekick, leaving Louise to die in Adam's arms.
15	* ''Series/AlexRider2020'': [[spoiler: Dr Greif plans to kill the pupils he's replaced with his clones. Stellenbosch goes to carry out the murders, only to find Kyra's already broken them out.]] [[spoiler: He falls victim to this trope himself when Yassen Gregorovitch murders him on the way to be interrogated.]] [[spoiler: Finally, the duplicate Alex is gunned down outside the school by Yassen Gregorovitch.]]
16	* ''Series/{{Alcatraz}}'': Garrett Stillman was once betrayed by his partner in crime so now he gets rid of all his accomplices after they have fulfilled their role. [[spoiler:He's also the victim of this trope, c/o Tommy Madsen]].
17	* ''Series/{{Arrow}}'': At the end of the first season, this, combined with HeKnowsTooMuch, is why [[spoiler:Malcolm]]/[[BigBad Dark Archer]] kills the scientists who built the Markov [[spoiler:earthquake-generating]] device for him upon its completion.
18	* ''Series/{{Attila}}'': Emperor Valentinian and his mother pull this on Flavius Aetius after he has defeated Attila, killing him on the basis that he's no longer useful to them.
19	* The pilot episode of ''Series/BattlestarGalactica1978'' had the Cylons kill [[TheMole Bal]][[EtTuBrute tar]] after they didn't need him anymore. [[note]]They also didn't trust him. Who would trust someone who would betray their own kind?[[/note]] This is changed for the series, when Baltar is spared by the new Imperious Leader because he's useful again.
20	* ''Series/TheBarrier'': Agents of the PoliceState don't seem to care much about people surviving their EnhancedInterrogationTechniques, as long as they get the information they need. When Álex gets taken out of the interrogation room by a police higher-up who is curious about information other than what he was interrogated about, he's convinced to give that information by being threatened to be sent back to the interrogation room and the reminder that his chances of leaving it alive are limited.
21	* ''Series/BattlestarGalactica2003'' plays this straight with Admiral Cain, shown in its full detail in the ''Razor'' flashback: during an attack on a Cylon staging ground, a large amount of Raiders jump in but Cain still orders her Viper compliment to launch in what is a blatant violation of her earlier promise of not sacrificing her underlings in a mad quest for revenge. Her XO calls her out on it, to lethal consequences.
22	-->'''Belzen:''' This is ''exactly'' what you said we wouldn't do. Even if we succeed, is this really worth the lives and planes what it'd cost?\
23	'''Cain:''' Mr. Belzen, are you refusing to carry out my orders?\
24	'''Belzen:''' Sir, I cannot in good conscience obey that.\
25	'''Cain:''' Mr. Belzen, [[YouHaveFailedMe give me your sidearm]]...\
26	'''Belzen:''' Sir?\
27	'''Cain:''' ''I said'', give me your sidearm! '''NOW!'''\
28	''[Belzen turns over his weapon, she immediately shoots him in the head with it in front of the crew]''\
29	'''Fisk:''' Gods...!\
30	'''Cain:''' Colonel Fisk... Colonel FISK! ''[Fisk steps up]'' [[YouAreInCommandNow You are now my XO]].
31	* In ''Series/TheBoys2019'', it's revealed that [[EvilInc Vought]] [[CorruptCorporateExecutive CEO Stan Edgar]] was the one who masterminded Soldier Boy being sold out to the Russians in order to more easily promote [[VillainWithGoodPublicity Homelander]].
32	* ''Series/BreakingBad'':
33	** When Walt is working under Gus, this problem continuously hangs over his head as his antics strain Gus' tolerance of him. Walt repeatedly has to find ways to keep from being replaced or rendered unnecessary, which would mean certain doom for him, and he knows the clock is ticking, because Gus has guards and security cameras watching his every move inside the Superlab, meaning it's only a matter of time before Gus can replicate Walt's formula. When Jesse proves he can closely replicate Walt's formula without Walt, Gus promptly fires Walt, although it's ultimately subverted as Jesse made a deal with Gus not to kill Walt. Gus agreed to the terms, and changes his target to Walt's ''family'' instead.
34	** When Jesse finds two of Gus' underlings using a kid as their assassin, he has to have Gus promise no more kids in the business for him to forgive them. Gus [[ExactWords agrees to the terms]], but later that same day, that kid is shot dead by the two guys since he's no longer of any use to them (whether Gus ordered the kid's death or the pair did it of their own volition is ambiguous). Things quickly go FromBadToWorse for everyone after that.
35	* In the first season of ''Series/TheBridge2011'', this happens to [[spoiler:Daniel Ferbe]], who is gassed to death in his car after [[spoiler:losing his job and no longer being useful as a spokesman for the killer]], and [[spoiler:the entire first group of terrorists]] in the second season, who are gassed to death in a shipping container after [[spoiler:coming under police suspicion]].
36	* ''Series/BuffyTheVampireSlayer'': The Mayor promises Principal Snyder a reward for his services. A few hours later, he eats him.
37	* ''Series/BurnNotice'': The organization that burned Michael has killing operatives who outlive the usefulness as standard protocol. They have a similar protocol for operatives who [[YouHaveFailedMe Have Failed Them]].
38	* ''Series/{{Cannon}}'': In "Flight Plan", the villain of the week leaves a trail of bodies behind him in his escape route across Mexico: killing each of his accomplices after they have fulfilled their part in his escape.
39	* Used in an episode of ''Series/{{CSI}}''. Three people work together rob a casino. One is killed by his partners at the scene. Another is killed sometime later. [[spoiler:The mastermind, who had killed the other two, is himself killed by a DirtyCop he had bribed earlier in the episode, who wanted all the spoils to himself.]]
40	** Another episode has several {{Monster Fangirl}}s show up to support a SerialKiller in his bid for freedom. In the end, one woman helps him escape, but as she's gushing about their new life together, she's killed by ''another'' woman. That one is then killed by still another in a later episode, and the last one is personally killed by the killer once her usefulness expires.
41	* ''Series/DoctorWho'':
42	** This exchange from [[Recap/DoctorWhoS28E13Doomsday "Doomsday"]] sums up the Daleks' attitude:
43	--->'''Rose:''' You didn't need to kill him!\
44	'''Dalek Sec:''' [[AC:Neither did we need him alive.]]
45	** The Cybermen kill their own programmed workhouse owners.
46	*** The Cybermen have even turned the statement that ILied before they "convert" whoever helped them into a catch phrase... though arguably from their perspective that's not killing them.
47	** [[Recap/DoctorWhoS13E3PyramidsOfMars "Pyramids of Mars"]]: The first thing Sutekh's [[TheDragon Dragon]] does on arriving is dispose of the minion who did all the preliminary work. Given that Sutekh plans to [[OmnicidalManiac destroy all life anyway]], from his point it's PragmaticVillainy.
48	--->'''Namin:''' Master, spare me. Spare me. I am a true servant of the great Sutekh.\
49	'''Dragon:''' ''I'' am the servant of Sutekh. He needs no other. ''[kills him]''

54	** [[Recap/DoctorWhoS29E4DaleksInManhattan "Daleks in Manhattan"]]: Diagoras, the human assisting the Daleks, has a foreman on the Empire State Building who threatens a work stoppage because of the speed Diagoras is demanding, as well as the unsafe conditions, hauled off by the Daleks to become either a pig-slave or one of the Dalek-human hybrids.
55	** [[Recap/DoctorWhoS30E1PartnersInCrime "Partners in Crime"]]: The Adiposian royal family decides to [[GravityIsAHarshMistress let their nanny go]] when she has Outlived her Usefulness regarding the illegal breeding of their new generation on Earth.
56	** [[Recap/DoctorWhoS30E5ThePoisonSky "The Poison Sky"]]: The Sontarans execute the human soldiers they brainwashed to serve them, and were planning on using their human pawn Rattigan and his students for target practice when they showed up, having lied to Rattigan that they would take him and his students to a (non-existent) planet that they could colonize.
57	** [[Recap/DoctorWhoS30E14TheNextDoctor "The Next Doctor"]]: Miss Hartigan has the mind-controlled workhouse masters after they've delivered the children in their care to her. She and the Cybermen then attempt to dispose of the kidnapped children after they've gotten the Cyberking's starter engine up to 100%, but the Doctor and company save the kids just in time.
58	** [[Recap/DoctorWhoS30E17E18TheEndOfTime "The End of Time"]]: After the Master opens the lock around the Time War, BigBad Rassilon reveals his plan to destroy the entire universe so the Time Lords can become beings of pure thought. With the Master's role fulfilled, Rassilon ''also'' declares he's going to personally vaporize him for being "diseased — albeit a disease of our own making."
59	** [[Recap/DoctorWhoS31E3VictoryOfTheDaleks "Victory of the Daleks"]] has the last three Daleks (made out of whatever hodge-podge genetic elements Davros could scrabble together) activate a progenitor device that creates new-model, redesigned Daleks... who, of course, decide to exterminate their saviors, because they're inferior. The three Daleks are perfectly okay with this and even agree with the new Daleks' assessment because... well, they're Daleks.
60	--->'''The Doctor:''' Blimey. What do you do to the ones who mess up?
61	** [[Recap/DoctorWhoS32E13TheWeddingOfRiverSong "The Wedding of River Song"]]: The Silence kill Madame Kovarian, not because of a specific failure, but because the best way to get at their enemies would happen to also kill her, and they hate their enemies more than they need her.

64	* ''Series/{{Ezel}}'': [[TheSociopath Temmuz]] calmly instructs a unnamed henchwoman to kill [[ChildrenForcedToKill Chucky]] after [[spoiler: he kills Tevfik,]] as he has "served his purpose". The order is particularly shocking as Chucky was [[SubvertedTrope set up]] as an expected MoralityPet -- not to mention he's no older than ''twelve'' at the very most.
65	* Subverted in ''Series/{{Farscape}}''; in an early episode, Crais nonchalantly killed a subordinate so no one else would know he had been recalled. When this was uncovered by his superiors much later, it was his downfall.
66	%%** Subverted again later. In the three-part episode "Look at the Princess", a palace servant betrays Crichton to Scorpius. Scorpius asks his lieutenant to "give her something special", and everyone expects this trope to occur. Instead, the servant dies because Crichton triggers automatic defenses. Later, we learn that Scorpius is a reasonably honorable man who treats his underlings well when they do their jobs, which means he probably ''did'' mean to give her something special.
67	%%*** Not quite. He tells Braca, who was to help the traitor finish her mission, to make sure there are "no. . . witnesses." He was pretty clearly intending to have her offed after Chrichton was picked up. Chrichton just beat him to it in his escape.
68	* ''Series/TheFBI'': In "The Assassin", the eponymous character kills the pilot who smuggled him across the border from Canada into the US.

71	--> '''Mal:''' "They killed Heinrich? Guess he wasn't useful anymore."
72	* This happens to [[spoiler:Max's boyfriend/colleague Tom]] in ''Series/TheFollowing''. Mark and Daisy extort him into helping them after they catch him with the corpse of a colleague he just murdered, after which Mark throws acid in his face and Daisy shoots him. Daisy is acutely aware that she may end up a victim of the trope at the hands of Theo.
73	* A woman kidnaps geniuses on ''Series/{{Fringe}}'' so she can get them to finish a formula. At the end, she gives the formula to a mysterious henchman, who tests it. The test successful, she has just enough time to stare in awe and exclaim it's amazing before the henchman pulls a gun and shoots her.
74	* ''Series/GameOfThrones'':
75	** Littlefinger kills Dontos Hollard for this and HeKnowsTooMuch.
76	** Ramsay has Tansy hunted down by his dogs just because he's gotten bored with her and Myranda is a tad jealous.
77	** The Master Torturer is tricked and murdered by Ramsay Snow in order to gain Theon's trust.
78	** As the war starts winding down, Tywin has no problem selling Gregor Clegane out to Oberyn Martell.
79	** King Maegor Targaryen had the builders of the Red Keep massacred to protect its secrets.
80	** In a heroic example, Sansa [[spoiler: executes Littlefinger once the Stark control of the North is achieved and she finds out the extent of his crimes.]]
81	* ''Series/GenV'': In "[[Recap/GenVS01E07Sick Sick]]" [[spoiler:Neuman]] meets the creator of a virus that can kill superpowered people in a parking garage. He hands over the virus; she confirms he is the only one who knows about it, promises him that he and his family will be safe—and then kills him by [[spoiler:making his head explode]].
82	* Narrowly averted in ''Series/{{Heroes}}'': [[spoiler:Arthur Petrelli]] says "I think you may have outlived your usefulness" to Linderman, who's savvy enough to take the hint and stop slacking. (Oh, and [[spoiler:betray Arthur by breaking his mind-control on Angela]].)
83	** The above perpetrator has [[spoiler:Adam Monroe]] abducted and brought to him so he can steal his power. The victim tries to bargain his way out of it, insisting he can be of use to him alive, but the man disagrees and steals his power, the act itself killing him.
84	* ''Series/HitlerTheRiseOfEvil'': Hitler is shown cultivating a close alliance with Ernst Rohm, particularly during his early years in Munich. However, when Rohm refuses to accept that the SA will never replace the German Army, Hitler purges the SA and has Rohm executed for "treason".
85	* ''Series/{{JAG}}'': In "Brig Break", once [[spoiler: Gunnery Sergeant Gentry has got the nukes]], he kills his accomplices.
86	* Happens in Episode 47 of ''Series/KamenRiderWizard'': [[spoiler:Now that 4 Wizards have been created, there's no need for any more Gates to be found, so Medusa soon becomes the victim of this trope.]]
87	* In ''Series/KyoryuSentaiZyuranger'', Daizujin has this attitude towards Burai following [[spoiler:"Reborn! The Ultimate God!"]]. During the Zyurangers' hibernation, Burai's body [[spoiler:got crushed by rocks]]. Daizyujin only cured him because [[spoiler:they needed six Zyurangers in order to unleash Ultimate Daizyujin]]. Unlike the others, Burai awoke with a [[DeathsHourglass magic candle]] that would cause him to die at a certain time following [[spoiler:Ultimate Daizujin's release]]. Daizyujin explained to the Zyurangers that they found it unnecessary for Burai to live beyond that event.
88	** Later, in ''Series/TensouSentaiGoseiger'', it was was revealed that this was partly the reason [[spoiler:Buredoran was on every villain team: Gain knowledge from each group- Warfare from the first, magic from the second, and technology from the third- and let them all fall when he perfected them so no one could interfere in his master plan, sometimes even ''orchestrating'' the fall.]] Most notably is [[spoiler:the third group, where he manipulates the Robogog and Metal-Alice into becoming severely weakened and then personally finishing them off. Soon after, while the Goseigers start talking about why Buredoran is doing this, Buredoran is currently taking over the third group's base and talking to himself about his plan, so the viewers can start to realize that Buredoran is the TRUE BigBad and that the three groups were expendable to him. At the end of the episode and the beginning of the next, it's confirmed that this is the case.]]
89	** Earlier, in ''Series/BattleFeverJ'', when BigBad Satan Egos [[MakeMyMonsterGrow grows to giant-size]] for the final battle, the transformation causes his castle to collapse on top of his last remaining henchwoman, Salome. It's not clear whether he did this deliberately, but he didn't seem too bothered either way.
90	** In several ''Franchise/SuperSentai'' series, especially during the '80s, a favorite tactic for disposing of useless, failing, or disobedient henchmen is to chuck them into the monster-making machine and mutate them into a mindless beast for the heroes to kill. ''Series/ChoushinseiFlashman'''s Emperor Lah Deus in particular was fond of this ploy, dispatching no less than seven unwanted minions thusly. [[spoiler: It's then [[HoistByHisOwnPetard turned right back on him]] in the finale when his treacherous head scientist sticks a knife in his back]].
91	* ''Series/Kingdom2019'': The Queen murders any mother in her care who has given birth, and also any female infant they give birth to. [[NiceJobFixingItVillain The trail of blood from an escaping mother raises the Royal Commander's suspicion and leads him to investigate into the conspiracy.]]

93	* In an episode of ''Series/TheLegendOfWilliamTell'', a summoned demon overhears two mooks discussing that the sorcerer will unsummon it when it has served its purpose. It's not happy about that. After the heroes have escaped, they discuss with the [[BigGood Kalem]] that they were lucky that the demon betrayed its master... at which point [[spoiler:Kalem polymorphs into a Mook before their eyes for a second]].
94	* In ''Series/{{Lexx}}'', His Divine Shadow was a parasitic Insect essence that would bond with human hosts to maintain the Divine Order dedicated to reviving his original Insect body. He would keep the hosts' brains around as Divine Predecessors which would act as advisors to the current incarnation as well as providing power. In "Gigashadow", the essence returns to its original body. When its essence makes contact with the Predecessors aboard the Lexx, they rejoice thinking it is their time of salvation. The Gigashadow has other ideas.
95	-->'''Predecessors:''' Gigashadow! It is our time of rejoicing!\
96	'''Gigashadow:''' Wrong! It is your time of pain! You are no longer needed, human vessels of my essence.\
97	''[the Gigashadow promptly pops each of the predecessors like grapes as they shriek in agony]''
98	* In the ''Series/LoisAndClark'' episode "Vatman" ([=S01E18=]), the villain drops this line verbatim while speaking to Superman.
99	* ''Series/TheMagician'': In "The Illusion of the Fatal Arrow", a hitman is worried that a psychic might be able to identify, decides that his junior partner is too much of a potential weak link and kills him before going after the psychic.
100	* Textbook example in ''Series/Merlin2008''. After a season of UnresolvedSexualTension and heavy subtext, Morgause finally gains control of Cenred's army and immediately has Cenred dispatched by one of his own men.
101	* In the revival of ''Series/MissionImpossible'', an episode has such order given to an underling (paraphrased):

103	* ''Series/MurdochMysteries'': In "This One Goes To Eleven", the murderer disposes of their accomplices once they have served their purpose; killing the two thieves after they have stolen the painting, and disposing of the forger when he threatens to become a liability.
104	* Jason Dean is sacrificed to ''Series/{{NCIS}}'' after killing Colonel Bell for his real employer.
105	* ''Series/NCISNewOrleans'': In "Sleeping With the Enemy", TheMole does this to one of his underlings; detonating the bomb he has just finished constructing in an attempt to make the NCIS team think that the underling was the mastermind and that he has just accidentally blown himself up, taking all of the explosives with him.
106	* ''Series/TheNewAvengers'': In "The Last of the Cybernauts...??", Kane employs Goff to get the Cybernauts working. Once they are operating, he quickly determines that Goff is only an engineer and incapable of making any improvements to the robots, he uses a Cybernaut to snap Goff's neck.

109	** He does this to [[spoiler:Amara and turns her into his staff.]]
110	** He eventually does this to [[spoiler:Anastasia after all. He uses her to make her wishes and give him the genie, then uses her as bait to get Will to tell him where his heart is. Once both tasks are complete, he decides he has no use for her and stabs her.]]
111	** He does it ''again'' to [[spoiler:the Jabberwocky immediately after achieving his goal.]]
112	* In ''Series/TheOuterLimits1995'' episode "[[Recap/TheOuterLimits1995S3E4LastSupper Last Supper]]", a MadScientist is on the trail of an immortal woman he wants to experiment on. When his assistant manages to find her, the scientist stabs him in the chest.
113	* ''Series/PersonOfInterest'':
114	** In the Season 1 episode "Mission Creep", Sam Latimer runs a ring of ex-soldiers turned criminals who conduct high-end robberies and noted for their discipline and efficiency (they can conduct a BankRobbery in no more than a minute). Later on we learn why they're so effective: whenever the gang gets erratic or becomes a liability, Latimer kills the gang and hires a new crew. At the end of the episode, [[spoiler:[[LaserGuidedKarma Latimer himself is killed by a client]] to tie up loose ends]].
115	** In Season 3, Team Machine repeatedly clashes against Vigilance, a faction similarly opposed to mass surveillance and government overreach ... but [[HeWhoFightsMonsters significantly more violent]] in their methods. Vigilance's leader, Peter Collier, is portrayed as a sympathetic character whose [[spoiler:older brother was falsely accused of terrorism and driven to suicide]]. At the end of the season, however, it's revealed that [[spoiler:Vigilance is secretly being funded and organized by Greer, the BigBad, and its actions used to convince the government to invest in Samaritan, Greer's AI surveillance system. Once Samaritan is approved and put online, Greer has no further use for Collier or his organization - and they become Samaritan's first target.]]
116	* In ''Series/PowerRangersJungleFury'', Dai Shi, the BigBad, and his [[TheDragon Dragon]] Camille, gleefully allows his overlords to be destroyed, two of them by the rangers and one by the Phantom Beast Generals, when they are no longer useful in his plans now that he has learned enough about his techniques from them. It has a lot to do with the fact that [[BearsAreBadNews Grizzaka]], the leader of the Overlords, has laid claim to Dai Shi's position. The honeymoon is over.
117	-->'''Camille:''' They've destroyed Carnisoar.\
118	'''Dai Shi:''' They did me a favor. One less overlord and a lot more power.

122	* ''Series/TheRookie2018'': [[spoiler:Armstrong]] is told to murder Nolan, and takes the gun willingly. It turns out [[ItWorksBetterWithBullets to be empty though]], and he's shot instead, presumably because (with his work for them revealed) he's of no more use to the mob.
123	* ''Series/TheShadowLine'':

After Van does his part by smuggling in a piece of kryptonite, Ian kills him. After Eric steals Clark's powers, he declares he's invincible and thus doesn't need Ian anymore, then throws him into a wall, presumably killing him.
130	** In "[[Recap/SmallvilleS03E22Covenant Covenant]]", [[spoiler:Jor-El's disposal of Kara]] after Clark discovers [[spoiler:she is not actually Kryptonian.]] Instead of the normal phrase, [[spoiler:he]] uses [[spoiler:"She served her purpose."]]
131	* Subverted in ''Series/StargateAtlantis'': [[spoiler:Michael, a villain known to have a low opinion of humanity in general]] takes a gun away from [[spoiler:a clone he created]] and tells him that he's "served his purpose"... then draws his own stun weapon and uses that to shoot him.

132	** Played completely straight, and stated word for word by a Wraith queen in regards to [[spoiler:Todd the Wraith]] in another episode.
133	* Franchise/StarTrek
134	** ''Series/StarTrekTheNextGeneration'': In the episode "Starship Mine", Kelsey, the leader of a terrorist group trying to [[EmptyQuiver steal the highly unstable toxic waste of Enterprise's engine core]], shoots one of her mooks after learning from him how to remove the [[AppliedPhlebotinum trilithium]] from its container.
135	** ''Series/StarTrekDeepSpaceNine'':
136	*** The Dominion used the Cardassians as help in invading Alpha Quadrant. And then it switched to [[spoiler:the Breen. And it was planning to betray them, too.]]
137	*** The Dominion is also in the habit of executing Jem'Hadar soldiers as soon as they show signs of insubordination, conscience, honour, or really anything other than fanatical devotion to the Founders.
138	*** The Dominion also outfits all Vorta with a [[CyanidePill termination implant]] that leads to almost immediate death for a Vorta who activates it. Vorta are expected to activate it if they are captured. Also if a superior officer or Founder demands it they would activate it. Late in the Dominion War the Female Changeling states that she would order Weyoun to activate it if the Dominion Alpha Quadrant cloning facilities were operational. This was after she ordered en entire team of Vorta researchers trying to find a cure for a new disease attacking the Founders because she felt they were [[YouHaveFailedMe not]] working hard enough to find that cure to activate their implants.
139	*** Kai Winn has no qualms about doing this with [[spoiler:Vedek Bareil. After he's injured during the middle of sensitive negotiations with Cardassia, she pushes for more extreme treatments right up until the treaty is signed. Then she says it's time to pull the plug]]. In Winn's defence, [[spoiler:Bariel was given enough choice to insist that he be a part of the talks by any means, and chose to let himself die after the talks were concluded]].
140	** ''Series/StarTrekDiscovery'': Lorca, in his verbose way, puts it plainly:
141	--->'''Lorca:''' Speaking of which, we've reached the tipping point, where your usefulness to me is outweighed by the risk of keeping you alive.
142	** ''Series/StarTrekPicard'': In "[[Recap/StarTrekPicardS1E06TheImpossibleBox The Impossible Box]]", after Narek gains information from Soji about her homeworld, he locks her inside a room and tries to kill her with his puzzle box, in which he had placed a tiny canister that emits a poisonous, radioactive gas. Fortunately for Soji, her android strength activates and she escapes by punching her way through the floor.
143	* ''Series/{{Supernatural}}'':
144	** In "It's the Great Pumpkin, Sam Winchester", Samhain does this to the witch who raised him. Not a nice way to reward several ''hundred'' years of summoning.
145	** And in Season 5, the demon Crowley helps the Winchesters in trying to stop the Apocalypse because he believes [[{{Satan}} Lucifer]] is going to pull this trope on the demons once he's won (Lucifer hates humans, and demons are corrupted human souls--do the math). He's right.
146	** Invoked by Dean in "Point Of No Return", where he says he'll only agree to become [[ArchangelMichael Michael's]] host if Michael pulls this on Zachariah first. After all, who's more important now?
147	--->'''Zachariah:''' You listen to me - you are nothing but a maggot, ''inside a worm's ass''. Do you know who I am?! After I deliver you to Michael?\
148	'''Dean:''' ''Expendable.''
149	** A somewhat unusual example happens in the Season 7 finale. Due to a deal, Crowley (who is now the king of hell) and his demons can't (actively) help the Winchesters fight the Leviathans. The demon Meg, who is fighting against Crowley, can. While the Winchesters don't turn on her, Crowley has his men grab her as soon as she has played her part.
150	* On Social Game shows such as ''Series/{{Survivor}}'', this is common. Some have noticed that typically when an alliance has all their threats down or, decides to turn on each other thinking the other target(s) are of no threat, this happens to one of two people. Either the person who carried the alliance through by winning challenges or making plans, or the low-man on the totem pole who just was another vote. More often than not, it's the first.
151	** Russell Hantz pulled one of these every other episode (which alliance-mate Natalie White was fully aware of and used as her cover).
152	* In ''Series/TeenWolf'', Kate offers to team up with Derek in exchange for giving her the identity of the Alpha. When she finds out that he doesn't know anything, she more or less declares this and tries to off him.
153	* In ''Series/TerminatorTheSarahConnorChronicles'', Terminators typically dispose of human subordinates this way once their objectives are completed, usually to prevent them from talking about sensitive information. At one point, Cameron uses a man and his sister to find information on the Turk, on the promise that she would help them deal with TheMafiya goons out to kill him. However, once she has the information she abandons them to be killed, since they serve no further purpose to her, and she doesn't have anything else invested in their survival.
154	* In the ''Series/TrueBlood'' episode "Release Me", [[BitchInSheepsClothing Maryann]] has her servant [[spoiler:Daphne]] put to death with a ritual dagger after thanking her for her efforts and service.
155	* ''Series/WalkerTexasRanger'': Many of the show's villains do this to their accomplices all the time, usually when they don't want to share any of the loot or to [[HeKnowsTooMuch prevent them from talking]] [[LeaveNoWitnesses before or after they are arrested]]. When it comes to killing off the accomplices, either the villains do it themselves or the Rangers do it for them; in the latter case, it's usually before the accomplices are arrested.
156	** Season 3's "[[Recap/WalkerTexasRangerS3E16AndS3E17WarZone War Zone]]" had the Rangers in pursuit of a gang of bank robbers in clown masks led by Mitch Bolton, who killed a fellow Ranger. After one of the mercenaries scream "Bolton" when another robbery is taking place, Bolton shoots him stone cold dead. However, Walker and Trivette heard him say Bolton's name, upon which they look up his information.
157	** During the beginning of Season 6's "[[Recap/WalkerTexasRangerS6E24TestOfFaith Test of Faith]]", Walker and Trivette are pursuing a trio of bank robbers and after they kill two of them, the leader gets away with an accomplice in a helicopter. [[HangingByTheFingers Walker hangs on for dear life by grabbing the copter's skid]], and eventually sidles up to the robbers and forces them to land so they can be arrested. Just before the landing, this exchange occurs between the leading robber and the helicopter pilot:
158	--->'''Pilot:''' Jeez, that was close with those Rangers.\
159	'''Lead Robber:''' Are you kidding? They did us a favor. Half million dollars in loot and two less guys to split it with. Hell, if they were here right now, I'd kiss 'em both.\
160	'''Walker:''' ''(holding the robbers at gunpoint)'' I'll pass on the kiss! Take it down!
161	** "[[Recap/WalkerTexasRangerS9E16SixHours 6 Hours]]" in Season 9 had the Rangers dealing with [[BodyguardBetrayal Theodore McNeely, the traitorous bodyguard]] of wealthy 16½-year-old Heather Preston, who kidnapped her and threatened to murder her [[MurderDotCom live on the internet]] [[RaceAgainstTheClock within]], [[ExactlyWhatItSaysOnTheTin well, six hours]]. After Heather is brought to [=McNeely's=] lair and restrained to her death chair, Edmund, one of the hired banquet gunmen, demands that [=McNeely=] pay him. How does [=McNeely=] do so? With a bullet to the chest! Then, he demands that his loyal pilot, William Borla, kill the other two gunmen who were arrested before they could be interrogated, so nobody can talk (especially also knowing [[BallroomBlitz two other gunmen were killed during the kidnapping]]).
162	** In another Season 9 episode, "[[Recap/WalkerTexasRangerS9E18Legends Legends]]", Michael Viscardi, the son of recently convicted Dallas mobster Samuel Viscardi, sought [[RoaringRampageOfRevenge revenge]] against the people involved in his father's trial, with Alex, the prosecuting attorney, being at the end of his list. He has his middle man, Dean Scaggs, hire blind hires to perpetrate the hits against those involved in the trial, then the hires are killed so nobody talks. Scaggs kills the hire who killed the head juror before Gage and Sydney could arrest him, but Trivette manages to arrest one of the hires who killed the judge, upon which he identifies Scaggs as the person who hired him. When Gage and Sydney get a warrant for Scaggs' arrest, Scaggs is killed by Michael after he is followed by the two Rangers to his office, just before Michael can proceed killing Alex, but Sydney was disguised as Alex the whole time while the real Alex was in hiding (due Walker having arranged extra protection for her and everyone else in the trial), upon which he and his two mooks have their butts easily handed to them by her and Walker.
163	* In Season 3 of ''Series/{{Warehouse 13}}'', this trope is why even ''thinking'' of siding with Walter Sykes is a very bad idea.
164	** Similarly, in the second season opener "Time Will Tell", Wells kills [=MacPherson=] by setting off his [[ExplosiveLeash Disintegrator Leash]] after he becomes a liability to her plan.
165	* ''Series/WeddingSeason'': Once [[spoiler:Metts becomes more of a liability than an asset to the Block by admitting the heroes have a recorded confession from her]] the boss has her brains blown out.
166	* ''Series/WizardsOfWaverlyPlace'':
167	-->'''Justin:''' What's... what's going on?\
168	'''Gorog:''' Oh, you'll soon see. You brought me the Moral Compass, so I'm done with you.
169	* ''Series/YoungSheldon'': In "Training Wheels and an Unleashed Chicken", Brenda apologizes for Billy's pet chicken Belinda scaring Sheldon and assures her it will never happen again. She then gives Mary a roasted chicken, strongly implying that she cooked Belinda.
