* {{Defied}} on the ''WebVideo/DreamSMP''. Quackity considers killing Slimecicle for overhearing a [[{{Futureshadowing}} conversation between him and Purpled]] because of this trope, but decides against it, instead choosing to utilize Slimecicle's HiddenInPlainSight abilities for his own purposes, and recruits him as a spy for Las Nevadas.

* In ''Manhua/GoddessCreationSystem'' the king passes away officially from wounds sustained in a tiger attack some months before but probably really from poison. To cover this up temporarily so they can keep things stable, the queen and her brother have the imperial doctor poisoned so he can't tell anyone.

* In ''VideoGame/YakuzaLikeADragon'', the Ijin Three agree that [[spoiler:Nanba]] cannot be allowed to live after he learns about their money counterfeiting scheme, with Zhao calling hitmen to take him out.

* What spells the undoing of [[spoiler:"Groovy Guy" Russel]] from ''Manga/BlackLagoon''. [[spoiler:When he catches on that resident NunTooHoly Eda happens to be a CIA agent. And in a spectacular display of foolishness, tells her this revelation to her face. He doesn't last long after that.]]

* In ''ComicBook/ThePunisherMAX'', this trope drives a great deal of the series' plot. Frank is induced into taking part in a highly illegal and dangerous black ops mission on behalf of a cabal of corrupt generals. The mission ends with a lot of dead civilians (not Frank's fault), a lot of dead Russian soldiers (definitely Frank's fault), the largest, deadliest terror attack in Russian history (the generals' fault) and the mission's actual objective a total bust (To be fair to Frank, that last part was deliberate). Unsurprisingly, any information pertaining to the mission is sealed and the generals attempt to have Frank killed several times [[spoiler: all of which fail and ultimately result in their deaths at Frank's hands.]]

* Another non-lethal variant in the ''WesternAnimation/Frozen2013'' fic ''[[https://www.fanfiction.net/s/11757317/1/Winter-Has-Come Winter Has Come]]''. The fic opens with Kristoff and Hans at Castle Black, the former having been sentenced to the [[Literature/ASongOfIceAndFire Night's Watch]] after an undisclosed incident involving the royal family of Arendelle. Even [[EvilPrince Hans]] can't help but ask him what happened, [[PetTheDog but quickly drops the subject when it becomes clear that Kristoff does not wish to speak of it.]] Toward the end, it is revealed that [[spoiler: Kristoff discovered [[BrotherSisterIncest Anna's sexual affair with her sister, Queen Elsa, who quickly used her powers to knock him out and the packed him on a cart destined for the Wall.]]]]

* ''Literature/TheChrysalids'': A heroic version. The protagonist is one of a number of secret telepaths living in a dystopian society where anyone discovered to have a mutation or genetic deviation is tortured or killed. His supportive uncle and SecretKeeper murders a nasty character who has discovered the group's secret and is on the point of exposing them, in order to save them from almost certain death.

''The'' most common motive for bad guys to go after innocent people, and also [[TruthInTelevision part of the reason that the U.S. Marshals has the Witness Protection Program]] (in addition to protecting witnesses from retribution ''after'' they testify).

* In ''Film/{{Serenity}}'', the Operative is sent after River because she picked up the secret of Miranda, which has been buried for twelve years, from the heads of top members of the Alliance's Parliament who came to the Academy to see her. The nature of the secret in question means that Parliament wants more than anything to keep it buried, even if it means River must die.
** This is a perfect example of the variant, since River was totally crazy, so she couldn't have communicated what she knew to anybody who could do anything about it. The Operative coming after her and the crew compelled them to find out the truth.

* "Literature/TalmaGordon": [[spoiler:Cameron's father was killed by Captain Gordon after helping him bury his treasure to keep the location secret. Cameron notes that this was a custom among pirates.]]

** When Hillshire learns the girl he just rescued had been turned into a cyborg killer, Jean gives him two options: become Triela's handler, where at least he can watch over her, or be murdered. Either way, he wasn't leaving the Agency a free man.
** It's also implied that [[spoiler:Claes's handler Raballo was killed because he wanted to reveal the Agency's existence]].

** When Saint Jaygarcia Saturn [[VillainNoLongerIdle prepares to join the fray in Egghead]], all lower-ranking Marines are ordered to clear the area at once and to avert their gaze, while also being warned that disobeying that order will not be forgiven. [[spoiler:When a hapless Marine foolishly looks on as Saturn unveils his Awakened Mythical Zoan form, the elder promptly kills him by [[YourHeadAsplode blowing up his head]].]]

* In Season 3 of ''WebAnimation/SonicForHire'', just as Franchise/{{Sonic}} and the gang are about to head towards [[VideoGame/SonicTheHedgehog2 Casino Zone]], Eggman decides [[VideoGame/YoNoid The Noid]]'s skills won't be required since he remembered that he never installed a security laser. After Tails pointed out that The Noid was already debriefed on the heist, Sonic immediately shoots him in the face.
