----
* ''Series/TwentyFour'': Jack Bauer has been called upon to do this sort of thing numerous times during the series run, often to create plausible deniability for higher-ups during times when he's not officially on CTU's payroll. Examples include executing and beheading a witness in a criminal prosecution (to get undercover with the man he was to rat out); staging the execution of a captured terrorist's children (to get him to talk); breaking the ringleader of a drug cartel out of a maximum security prison (to intercept a bio-weapon his cartel was about to buy); threatening to expose a terrorist's innocent daughter to a fatal virus (to make him talk); threatening to kill a suspect whose lawyer had exempted him from questioning (again, to make him talk); invading the Chinese consulate and kidnapping a Chinese national, and sacrificing his lover's estranged husband (who [[TakingTheBullet took a bullet]] for Jack early in the day) to save said national, ultimately ending up in a Chinese prison for it (to insulate the US government from reprisal); and hijacking Marine One and ''holding the President hostage'' (to get a confession of the crimes he'd committed). He also does shoot a dog, but that was in self defence. His shooting dead of [[spoiler:Nina Myers]] in Season 3, on the other hand, was plain revenge-fuelled murder.
* ''Series/{{Angel}}'': The crew, consistently and awesomely due to this show being DarkerAndEdgier than its parent show. For example, Wesley torturing a female druggie, Angel allowing Darla and Drusilla to kill a lot of Wolfram & Hart employees, and anything the recurring villain Holtz ever does.
* ''AshesToAshes'': Season 2 sees Gene Hunt shoot the dog.
* ''Series/BabylonFive'': This show is full of this. Then again, every race and every individual in Babspace is a MagnificentBastard -- even the heroes are like this at times.
** Even one of the most sympathetic and innocent characters in the series, Vir Cotto, has done this. [[spoiler:He was the one who actually killed [[TheCaligula Emperor Cartagia]].]] A necessary action, if extreme, and no one ([[DirtyBusiness least of all him]]) wished that it had to be done.
* ''Bangkok Hilton'': In the backstory, Hal Stanton thwarted a plan by Allied soldiers to escape from a Japanese POW camp in Thailand, as he knew that their captors would execute two prisoners for every one that escaped, a factor that the escapees refused to take into account. The worst part? If he had let them go, the war would have been over before any reprisals would have happened.
* ''Series/BattlestarGalacticaReimagined'':
** Has made this an almost weekly theme. Laura Roslin and Saul Tigh are the show's unquestioned champions - the former going so far as to kidnap and fake the death of a newborn unbeknownst to her parents and the latter going so far as to poison his own wife in order to give her a peaceful death after she was caught collaborating with the Cylons. (Probably the kindest thing he could have done, seeing what happens to ''other'' collaborators in the very next episode.) [[spoiler:Reports of her death might have been exaggerated.]]
** Al-Queda-style suicide bombing and planned genocide via biological weapon!
** Canine execution via firearms starts up in the pilot miniseries and just keeps on going. Leaving behind ships that can't jump to FTL and Helo gunning down a man trying to jump onto an already-full Raptor are just two of the ugly decisions characters make. And [[FromBadToWorse things get worse as the series progresses.]]
** Things get pretty dark pretty fast on that show.
* ''Series/BlakesSeven'': In one episode, Vila orders a pro-Federation surgeon to operate on a fellow rebel at gunpoint, then says that Blake isn't the sort of person to do this. [[spoiler: Then a few minutes later, Blake subverts this trope by [[BewareTheNiceOnes threatening to cripple the surgeon's hands if he delays any longer]].]]
* ''Series/{{Bones}}'': Played with in the episode "The Man in the Cell". Bad guy Epps goes over the balcony rail, Booth lunges and [[TakeMyHand catches his wrist]], there's a long moment (and some really creepy dialogue from Epps)...and then Epps is street pizza. Did Booth let go or not? This turns into a sub-arc over the next few episodes.
* ''Series/BreakingBad'':
** [[spoiler:Jesse is forced to kill Gail in order to prevent Walter's execution.]] When he tries to talk about his reaction to the incident at [[spoiler:rehab]], he even states that he was forced to put down a dog.
** Then in Season 5/Episode 5, [[spoiler:Todd shoots the boy on the dirt bike.]]
* ''Series/BuffyTheVampireSlayer'':
** Giles prevents the hellgoddess Glory from ever returning by [[spoiler: [[CoupDeGrace suffocating]] [[SealedInsideAPersonShapedCan her human vessel]] Ben. He specifies that he's doing this because...or so that...Buffy never would. (The page quote comes from earlier in that episode, where he foresees having to do such a thing with Dawn.)]]
** This does create some MoralDissonance because only two episodes previously, Buffy's fight with the Knights of Byzantium explicitly resulted in nearly a dozen deaths, including one knight killed when Buffy ''threw an axe into his chest.'' This, however, happened in battle with well-armed and armored warriors, not to a currently-helpless, badly-injured person.
** In a later season, the show having gotten a bit darker or at least grayer, Giles confronts Buffy about whether she would make the same choice again (Dawn vs. Saving the World) and she admits that life has taught her some dogs have to be shot and now she would sacrifice even Dawn if she had to in order to prevent the Apocalypse. She even outright tells Principal Wood she would be willing to let Spike kill him if Wood forces the issue, because Spike is the more useful soldier in the coming battle and she has to make the tough decisions if the world is going to survive.
** Buffy herself has had to shoot the dog. In "Becoming, Part II", [[spoiler:seconds after her vampire boyfriend Angel has his soul restored, the ritual he performed when he was the soulless Angelus kicks off and threatens to drag all of Earth into Hell. The only way Buffy can save the world is by killing Angel and consigning him to Hell instead...which she does]].
** Wesley tries to get the group to do this when the BigBad of Season 3 tries to bargain with them using Willow as a hostage. Wesley argues that the potential death of tens of thousands if they accept the deal far outweighs the certain death of one person if they refuse. [[spoiler: Willow's boyfriend Oz breaks the AppliedPhlebotinum that would be used to destroy the Box of Gavrok. The Scoobies give the BigBad the box in exchange for Willow, deciding to simply ignore Wesley from that point on. It's in stark contrast to the ''{{Series/Angel}}'' spin-off where Wesley's sort of advice tends to be the decision that's often much more likely to be taken.]]
** Heck this was started as far back as the second episode after Jesse, Willow and Xander's longtime friend, winds up turned into a vampire. Before the final confrontation with Luke, Giles makes it clear to the two that while he may look like their friend, it's really nothing more then a monster and that they ''will'' have to kill him. [[spoiler: When all said and done, Jesse winds up dispatched purely by accident.]]
** In Season 9, this is Whistler regarding his actions in season 8. His plan was to create a better world where good and evil were balanced even if it meant sacrificing billions of people's lives.
* ''Series/BurnNotice'':
** In the season 2 finale, [[spoiler:Michael has to kill Victor. It's partly a MercyKill, since Victor says that the people who're after them will take him apart if they get him, but it's mostly just an expedient move for Michael in order to get closer to the people who burned him. Considering Victor was trying to kill Michael up until about halfway through this episode]], it's a TearJerker. Especially since the good guys have gone out of their way to avoid directly killing ''anyone'' after ten minutes into the first episode.
** And in the season 3 episode "The Long Way Back", [[spoiler:Michael shoots his "partner" Strickler, upon finding out that he had arranged for Fiona to be kidnapped and handed over to any one of the various people who wanted her dead, simply because she was a potential red flag in Michael's file. Strickler had already pulled a gun on him at that point, and was not particularly inclined to let Michael do anything to prevent the plan from going through.]]
* ''Series/{{Charmed}}'':
** Happens quite a lot:
** The season 1 finale saw the sisters getting attacked by a demon who had a master of time on his side so that whenever the demon himself was killed by the sisters, [[GroundhogDayLoop the day would rewind and start over]]. The sisters discovered that the only way to stop this was to allow the day to end without vanquishing the demon. Prue cast a spell to fast forward the rest of the day but it meant letting Andy die as he had sacrificed himself to save the sisters in the third version of the day (Phoebe and Piper had died in the previous two versions instead).
** The episode "A Witch In Time" had Phoebe getting a premonition of her boyfriend dying in a robbery and she saved him, only for the [[BalancingDeathsBooks Angel of Death to keep trying to kill him]] that resulted in her and Paige being killed by demons. Piper went back in time and was forced to give Phoebe the wrong directions during the robbery so that her boyfriend would be killed this time.
** Phoebe's rebellious high school self eventually took over her and she busted an old school friend out of prison and he went on a rampage, using her powers to his advantage. Once the cops were after him again, he ordered her to change his appearance magically. She and Paige made him look like Chris who was being hunted by demons. The demons then appeared and killed the man, thinking him to be Chris.
* ''Series/DoctorWho'':
** The Doctor has often found himself taking this role; it's especially become a character trait in his ninth and tenth incarnations. Instances include, in "Dalek" sealing his companion in a bunker with a Dalek in order to prevent the Dalek from escaping, and drowning the ''children'' of a GiantSpider [[HiveQueen Empress]] in "The Runaway Bride" rather than letting them devour the Earth.
** However, the Ninth Doctor [[CrowningMomentOfHeartwarming gloriously subverts]] this trope in "The Parting of the Ways". Poised with a weapon capable of destroying the Dalek Emperor's fleet - along with all of Earth - he cannot pull the trigger. It's all the more satisfying (though [[{{Tearjerker}} heartbreaking]]) given his actions in "Dalek".
** Arguably the worst example shown so far is in "The Fire of Pompeii", [[spoiler:causing the eruption of Mt. Vesuvius, and the destruction of Pompeii, in order to save the rest of humanity from being turned into Pyroviles.]]
** He also [[spoiler:destroyed his entire species in order to end the Time War? Sure, the Time Lord authorities had gone OmnicidalManiac by that point, but he killed everyone on Gallifrey, which presumably included innocents.]]
*** In ''The Day Of The Doctor'', [[spoiler: Eleven meets the former self who actually shot this particular dog, as well as Ten, and together [[CrowningMomentOfAwesome they manage to avert the trope by forcing Gallifrey to disappear intact, rather than destroying it.]]]]
** In the Literature/DoctorWhoNewAdventures novels set during his seventh incarnation, he would commit such morally questionable acts so often that he quickly turned into a KnightTemplar, and remained so for most of the series.
** In Eleventh Doctor episode "The Girl Who Waited", [[spoiler: the Doctor tricks an older version of Amy into believing she can escape after thirty six years imprisonment, so she'll help him save the younger Amy from being imprisoned and thus becoming her in the first place. [[ILied He's lying]] - the paradox cannot be maintained and one Amy must die. When she attempts a MeadowRun towards him, he slams the TARDIS doors closed, leaving her to die. And then he gives the gun for Rory to shoot with a SadisticChoice: Rory must pick which Amy he wants to save.]]
** The stand-out moment for the Fourth Doctor doing this has got to be him forcing Davros into ordering the destruction of the prototype Daleks by holding down his life support shutoff switch to torture him.
* ''Series/{{Farscape}}'':
** Has Crais offering to execute Aeryn's mother (who was sent to hunt them down and kill them) after they capture her so Aeryn doesn't have to witness it. He doesn't actually 'shoot the dog', he fakes it and offers a proposal to Aeryn's mom where she returns to the Peacekeepers and says the job is done in exchange for her life. Technically averted...
** No, that's technically a DoubleSubversion. In a later episode, Crais DOES shoot Aeryn's mother to save Aeryn's life. Which is exactly the kinda material this trope is made of.
* ''Series/{{Firefly}}'':
** Mal is the rare lead character who never needs a side character to shoot the dog for him. He's more than willing to kill someone to protect his crew, and he does it on multiple occasions, even when killing them isn't strictly necessary.
** ''In regards to the following three examples, it should probably be said that every single time Mal Shoots The Dog he is doing so because his patience level has reached Zero. Each time you can almost hear him say; "I don't have time for your Hshuō bādo."''.
** In the pilot, he shoots Dobson (a federal agent) in the face without hesitation because Dobson was threatening River.
** In ''The Train Job'', he kicks the KingMook into Serenity's engines-- shredding the man into a mist of blood-- because he threatened to hunt them down over a deal gone bad.
** In ''The Message'', he shoots Tracy for trying to take Kaylee hostage, when a simple explanation of the situation would have solved everything. But would Tracy have listened?
** The culmination of Mal's "Shoot the Dog for the crew" mentality is shown in ''Ariel'' where he fully intends to space ''one of his own crew'' for trying to sell out two others for reward money.
* ''Series/{{House}}'': Had its doctors treat an Idi Amin-analogue called Dbala. Cameron says repeatedly that she hopes he dies, and makes moves toward convincing his second-in-command to seize power by killing him, but still treats him as best she can. [[spoiler: Then her husband Chase instinctively calls out a warning that thwarts an assassin. Later, he hears the assassin's backstory (and some of the dictator's genocidal rant), and decides he can't live with having saved this monster's life, so he fakes a test result, deliberately causing the dictator's death, which eventually causes Cameron to leave him and Princeton Plainsboro Teaching Hospital.]]
* ''Series/LawAndOrderSpecialVictimsUnit'': In the episode "Rage," Olivia shoots the perp engaged in a [[ItsPersonal personal battle]] of wills and wits with Elliot because she knew he wanted Elliot to shoot him since IfYouKillHimYouWillBeJustLikeHim.
* ''Series/{{Lost}}'':
** Eko shoots a man to keep his little brother from having to do so.
** Later, a flashback shows Sayid killing a chicken on his father's order after his older brother refuses to do so.
** The time [[spoiler: Sayid shot 12-year-old Ben Linus]] to try and avert all kinds of bad stuff in the future.
* ''Series/{{Merlin1998}}'': In this series, Merlin helps Uther rape Igraine by deceit, reasoning that it will stop the war, save many lives, and result in Arthur's birth.
* ''Series/{{Merlin}}'': In the new BBC series, Merlin is forced to [[spoiler: poison Morgana, who he has been lying to about her magic and hiding his own from, because she is the vessel for a curse that has caused all of Camelot to fall into a sleep they cannot awaken from. Admittedly, his hand was forced by Kilgharrah the dragon and Morgause only made things worse, but up until that point, he had viewed Morgana as a great friend and there was even a little bit of romance between them. He also betrayed the location of a Druid camp that he'd led Morgana to in hopes that she would learn more about her magic because Uther was hunting down innocent people and killing them to find her. This also kickstarted Mordred's hatred of Merlin.]]
* ''Series/{{NCIS}}'': Gibbs shooting through Agent [[spoiler: Michelle Lee to take out the Weatherman. And she asked him to do it]]! Complete TearJerker, right there.
* ''Series/NewTricks'': A literal example of this trope is demonstrated in the pilot's opening after Sandra Pullman shoots a dog in self-defense during a bust on an Asian cockfighting ring. This incident and the bad publicity that results leads to her being assigned to start the Unsolved Crimes and Open Cases Squad (UCOS), the premise of the series.
** "You shoot one dog in this country!"
* ''Series/PieInTheSky'': There's one episode where WPC Cambridge arrests an old police friend of Crabbe who's guilty of taking a bribe, to spare Crabbe from having to do so.
* ''Series/{{Revolution}}'':
** To put it bluntly, one must perform this trope to survive in the post-blackout world.
** In [[Recap/RevolutionS1E2ChainedHeat episode 2]], [[spoiler: Rachel Matheson shot the Wiry Stranger to prevent him from stealing their food and because he put her little daughter Charlie in danger]].
** In [[Recap/RevolutionS1E8TiesThatBind episode 8]], [[spoiler: Tom Neville revealed to Monroe that Tom's friend Colonel John Faber's son was a rebel in order to prevent his son Jason from being executed and from being sent to California. In case you're wondering, Faber's son and his cohorts were shot on the spot off-screen, and the colonel is last seen being tortured on-screen because Monroe is not sure where the colonel's loyalties lie. Tom Neville had to have known that this would happen]].
** In [[Recap/RevolutionS1E9Kashmir episode 9]], [[spoiler:Rachel stabs Dr. Bradley Jaffe to death so Monroe won't kill her and her son [[YouHaveOutlivedYourUsefulness for no longer being of value to him]]]].
** In [[Recap/RevolutionS1E14TheNightTheLightsWentOutInGeorgia episode 14]], [[spoiler: Miles Matheson wants Charlie to kill some Georgian soldiers to get their uniforms. SubvertedTrope, because Alec Penner had already killed those Georgian soldiers]].
** In [[Recap/RevolutionS1E16TheLoveBoat episode 16]], [[spoiler: Rachel shot Curt Thompson because he was going to shoot her and Aaron for stealing his food]].
** In [[Recap/RevolutionS1E17TheLongestDay episode 17]], [[spoiler: Rachel knocks out Lee Blackmore and leaves Blackmore's son to die. DeconstructedTrope, because she reveals to Aaron that she's not doing any of this for the greater good, but because she wants revenge against Monroe for Danny's death. In other words, she's doing it not because it's necessary, but because it's easier]].
** In [[Recap/RevolutionS1E20TheDarkTower the first season finale]], [[spoiler: Rachel wanted to abandon the wounded Nora Clayton in order to get the power back on, and Nora even urged them to just leave her. Charlie makes this a DefiedTrope by pointing out that this is not an either-or situation. So, Rachel and Aaron go to get the power back on, while Charlie and Miles go to get Nora to the infirmary]].
* ''Series/{{Sherlock}}'': John shoots the killer cabbie in the first episode to stop Sherlock from giving into his ego and eating a pill that has a 50/50 chance of killing him.
* ''Series/{{Smallville}}'':
** Lionel and Lex Luthor have both done this at some point, although in the most iconic cases of both, [[TheDogShotFirst they were protecting someone else]].
** Lana Lang, Pete Ross, and Oliver Queen also used this ideology as justification for attacking Lex with lethal intent while under the influence of mind-altering substances. It seemed like this was the case for Kara Kent as well, but that was simply [[spoiler:Brainiac in disguise]].
* ''Series/StargateSG1'':
** Happens at least twice. Both times, it's a member of SG-1 killing someone dear to Daniel and explaining "IDidWhatIHadToDo".
** In the first episode of ''Series/StargateAtlantis'', Shepherd has to kill [[spoiler: his CO]] after the latter has the life sucked out of him by a Wraith.
* ''Series/StarTrekDeepSpaceNine'':
** Has several examples:
** Section 31 is a secret group in Starfleet, which [[UtopiaJustifiesTheMeans performs rather shady actions while giving Starfleet plausible deniability]]. Suspicious fans wondered if this was LampshadeHanging to explain how the on-screen portrayal of the Federation became less idealistic over time.
** "In the Pale Moonlight": Garak and Sisko hatch a morally ambiguous plot to frame the Dominion for plotting an attack on the Romulan Empire, in order to get them to join in the war effort. This plot was recognized as a fake by a Romulan Senator who was [[spoiler:promptly murdered by Garak]]. Though angry at first, Sisko eventually came to grudgingly accept that it was a necessity. While some fans consider this to be one of the best episodes in the entire series, others interpret Sisko's attitude at the end of the episode as StupidGood; Garak did what Sisko's plan logically led to, but Sisko kept clinging to a vision of himself that was incompatible with what he actually wanted -- Romulan intervention in the war to save Earth and the Federation. Then again, Garak explicitly calls him on this ("That's why you brought me in, remember?") and points out that the self-respect of one Star Fleet officer (plus a few not-so-innocent dogs getting shot) is well worth it as a cost for saving their entire region of the galaxy from the Dominion in the long-run.
* ''Series/StarTrekEnterprise'': Has an episode in the third season where Archer [[JackBauerInterrogationTechnique tosses a man into an airlock and then drains the air to torture him for information]]. Another episode had them commit an act of piracy in desperation later in the season.
* ''Series/StarTrekTheOriginalSeries'': In the second pilot "Where No Man Has Gone Before", Spock recommends that Gary Mitchell be killed before his [[AGodAmI growing power]] gets completely out of hand. Kirk initially rejects the suggestion in favor of merely marooning Mitchell, but finally realizes that he has no choice (and almost gets killed himself because he hesitates the first time he has an opportunity to go through with it).
* ''Series/StarTrekVoyager'': In "Prime Factors" Voyager's crew come across a race of aliens who have the technology to get them home, but who refuse to help them. A faction within their society agrees to covertly give them the technology in exchange for Voyager's library (stories being used as currency). However the transaction is illegal and Janeway refuses on principle. Some of the more militant crewmembers decide otherwise, only to be busted by Security Chief Tuvok, who then proceeds to make the exchange himself.
-->'''Janeway''': I don't even know where to start. I want you to explain to me how you, of all people, could be involved in this.
-->'''Tuvok''': It is quite simple, Captain. You have made it clear on many occasions that your highest goal for the crew is to get them home. But in this instance, your standards would not allow you to violate Sikaran law. Someone had to spare you the ethical dilemma. I was the logical choice, and so I chose to act.
* ''Series/{{Supernatural}}'':
** More like "Shoot the Werewolf" in "Heart". Madison is a sweet, engaging {{Girl of the Week}} but also a danger to herself and everyone around her. She asks Sam (who's slightly in love) to do it as he's the only one she trusts, and she's [[ICannotSelfTerminate unable to do it herself]]. Dean offers to do it but instead we [[SoundOnlyDeath hear a shot offscreen]] and end on Dean looking miserable and flinching.
** This is Sam's character arc for season 4. Even with how badly it turned out, his intentions were good. This happens again in season 6 when [[SoullessShell Sam temporarily loses his soul]] and is [[OurSoulsAreDifferent willing to do anything]] (including letting his brother get turned into a vampire) to get the job done.
* ''Franchise/{{Terminator}}: Series/TheSarahConnorChronicles'':
** Finds a new dog to shoot in virtually every episode (as could be expected, given the [[TheEndOfTheWorldAsWeKnowIt consequences of failure]] and the presence of an emotionless android and a paranoid future soldier in the regular cast). For instance, in an early episode, the benign terminator Cameron prevents John from saving a suicidal girl, reasoning that he could draw attention to himself and risk getting exposed and drawing the attention of other terminators. The biggest example is Andy [[MeaningfulName Good]], an innocent computer engineer who will one day invent [=SkyNet=], who gets shot (though Sarah's pretty upset about it).
** In the episode "The Brothers of Nablus," Cameron guns down three thieves who stole from their house, simply because they knew where the Connors lived. [[spoiler: Sarah spares the last robber, who was hiding in the bathroom. Cromartie eventually comes along and susses the location of the Connor's house from him.]]
* ''Series/{{Torchwood}}'':
** Jack Harkness has taken up this role quite a few times, starting with [[spoiler:giving a child to [[FairFolk evil fairies]] to keep them from murdering innocents in "Small Worlds"]] and going up to [[spoiler:sacrificing his own grandson in order to save millions of other children in ''Children of Earth'']].
** A couple of more literal examples in killing Suzie and Lisa. Jack is very Needs of the Many guy.
* ''Series/TheWestWing'': Ends season 3 with Bartlet reluctantly ordering the assassination of terrorist leader and foreign diplomat Abdul Shareef. Bartlet sees this as an absolute wrong, but flawed evidence gathering prevents them from putting him on trial, and Leo convinces him that it's the only way to prevent future terrorist attacks.
* ''Series/TheWire'': Done straight in Season Three where Cheese shoots his dog and the police mistake it as code and question him if he killed any of the murders that have been happening.
* ''Series/XenaWarriorPrincess'':
** Ironic reversal: had Gabrielle saving her potentially-future-demonic-minion infant daughter Hope by ''not'' killing her in secret. Later events strongly indicate she probably should have.
** Later events also give the impression that it might not have worked ([[spoiler:she came back from being poisoned and the body burned, after all]]) ''and'' that Gabrielle might have been correct all along: Hope clearly cared for her mother and was hurt about being abandoned. Perhaps being brought up by a loving parent to teach her right from wrong might have done some good. Or perhaps not. Regardless, secretly not-killing her clearly didn't help.
