A scene in which someone is in mortal danger, but the one person nearby who could help that individual doesn't care, or doesn't realize the extent of the danger. That person isn't necessarily the villain — after all, they're not necessarily causing the emergency — and may very well be nothing more than a complete jerk, but either way, the endangered individual's brush with death is brushed off as unimportant by someone who has the potential to help out.
This can make the jerk be even more of a jerk, to the point of possibly being seen as evil, and can at times be far more disturbing than a genuine villain threatening others' lives. At least the villain both has a motive (even if it's simply enjoying the suffering they're causing) and is known to be evil (at least by the audience, if not the heroes or everyone in the setting) — you're not really surprised by their antisocial behavior. But the bully who lets someone die because he doesn't care is a whole new level in itself. It's not quite a Moral Event Horizon (in most cases), but it's certainly reprehensible.
- One recurring bystander in The Dark Knight Returns demonstrates this repeatedly, compounding it with a "not my problem" attitude.
- At the end of the first miniseries of The Punisher, Frank had forced the Big Bad to confess his deeds to Ben Urich. On his way out of the villain's estate, he's confronted by the son of a mafioso he shot, and Castle did not want to kill him (said son was not involved in the family business at all). He tells the man that sometimes, the best course of action is to do nothing; the son allows him to leave without incident. Shortly afterwards, the big bad's girlfriend (who did a FaceHeel Turn and tried to kill the Punisher), sees him leaving the estate, and tries to run him down. She ends up with her car halfway off the side of a bridge, and Frank thinks about how sometimes, the best course of action is to do nothing, leaving her to her fate. Unfortunately for Castle, both she and the Big Bad return to plague him again.
- One of the most famous examples is the titular character in the Spider-Man franchise. In most incarnations, upon receiving his powers, Spider-Man tried to figure out how best to exploit them for profit and, while walking through a TV Studio, ignored a burglar running past (and a security guard's calls for him to help), dismissing the incident as "not his problem", given that he wasn't in the business of fighting crime. In a particularly brutal instance of Laser-Guided Karma, the burglar kills his Uncle Ben that very night.
- In The Incredibles, Bob (Mr. Incredible) notices during a meeting with his boss Mr. Huph that a man is being mugged and beaten up in the alley outside his window. Mr. Huph replies glibly, "Well, let's hope we don't cover him!" He then threatens to fire Bob if he leaves the meeting to stop the mugger. Bob doesn't take it very well.
- In Casper: A Spirited Beginning, a bully locks a boy in the closet of a house which is about to be demolished. The bully is unaware that the house is going to be demolished, but his victim is in mortal danger. And even when he's told, his only response is "Cool!"
- Averted in the live action Grinch movie when Cindy Lou Who falls onto a conveyor belt leading to a crusher and can't get up. The Grinch wants to be this trope as part of his self image but ultimately can't bring himself to let her get hurt and saves her.
- In the first Halloween movie, one of the children Laurie Strode is babysitting does come to help her when she's banging on the door, begging him to let her in before Michael Myers catches up with her. However, he only walks to the door, and is visibly bored and annoyed with her demands, completely oblivious to the terror in her voice, albeit unaware that Michael is on the prowl.
- In the World War II movie Sahara (1943), the tank crew abandons an Italian soldier taken prisoner in the war in the middle of the desert, citing a lack of resources. They go back for him, but not before heartlessly driving off and condemning him to what would be a painful, slow death.
- Downplayed in the first Spiderman movie starring Tobey Maguire, as the victim of the robbery had just screwed Peter out of a lot of money via Loophole Abuse, and brushed him off with, "I missed the part where that was my problem," when he protested... words that Peter gleefully throws back in the guy's face as the robber gets away. This Moment of Weakness still comes back to haunt him as standard.
- In Charlie and the Chocolate Factory and its many adaptations, this is zig-zagged with Willy Wonka, who is a Jerk with a Heart of Gold. Because the four bratty kids get into possibly-lethal danger when they disobey his explicit instructions and warnings, he has No Sympathy — as everyone else panics, he watches calmly as their fates play out, even snarking and/or laughing. And he worries more about how the smooth operations of his factory will be affected. Then again, this is his factory, so he knows how they can be rescued and/or restored to normal and takes steps to ensure that they are. Then again, he's perfectly willing to brush off the possibility that Veruca and her parents will be burned alive in an incinerator, and it's luck that saves them. Then again, the brats are all Hate Sinks, rather than the innocent victims usually associated with this trope — the reader is ultimately supposed to feel great satisfaction in their comeuppances. This is a major reason Mr. Wonka is an Interpretative Character subject to Alternative Character Interpretations, such as the 2013 stage musical portraying him as an Ambiguously Evil Anti-Hero who isn't perturbed by the prospect of the kids actually getting killed.
- In the Frightmares book titled Bone Breath and the Vandals, a group of teenage vandals tie and gag a middle school girl and leave her in a dumpster. The dumpster is loaded onto a dump truck, and she is about to be crushed to death, but is saved through luck. Naturally, the vandals had no idea they were leaving her to her death.
- Drives the entire plot of the 2010 Doctor Who Christmas special "A Christmas Carol": a spaceship liner is about to crash and the only device that can save them can only be operated by a rich curmudgeon who refuses to use it apparently just because he doesn't care. Cue Yet Another Christmas Carol.
- In Game of Thrones, Jaime Lannister points out to Cersei that should the Crown not hold up to their bargain and aid the Targaryen-Northmen alliance against the Night King and his Army of the Undead, then the South should fully expect a punitive expedition driven by righteous anger and vengeance at the lack of gratitude. And that's exactly what happens when the Battle for the Dawn is won and Daenerys and her forces unleash a Roaring Rampage of Revenge on King's Landing.
Jaime: If the dead win, they march south and kill us all. If the living win and we've betrayed them, they march south and kill us all!
- The final episode of Seinfeld had the main characters standing by and laughing as a fat guy was mugged (even filming it). They're arrested and charged under Good Samaritan laws. Of course, in reality "Good Samaritan Laws", rather than requiring people to put themselves in harm's way or face legal penalties, do almost the exact opposite: protecting people who make a good faith effort to help others in an emergency (like trying to perform CPR without being trained) from being sued for damages if they end up doing more harm than good.
- Finn exhibits this multiple times in Dawn of a New Age: Oldport Blues. When they're attacked by snake apparitions, and the other children are in a panic, he's utterly indifferent and even tells them to shut up. The next night, when Michal accidentally sets himself on fire, the other students desperately try to find a way to put him out while Finn ignores it in favour of skimming through his phone.
- In Ambition Yale won't help you escape from the people who just threatened to murder you because he's too busy holding a dinner party.
- Azama in Fire Emblem Fates has this sort of nihilistic detachment as one of his main traits since he believes everything is predetermined and that life is meaningless since everyone is destined to die someday, so he sees everything bad that happens, up to and including the deaths of himself and people close to him, as nothing but nature taking its course. In the cutscene that introduces him, his fellow bodyguard for Princess Hinoka begins sinking into quicksand in the middle of a battle, and rather than help her, he just shrugs, admits he isn't strong enough to pull her out, and stands back to watch what happens, forcing Hinoka to step in and pull her out herself. In the opening to his daughter's recruitment chapter, Saizo is left shocked by Azama's rather flippant reaction to finding out the village his daughter lives in has been overrun by enemy forces and doesn't show any concern for her until he gets to the village and doesn't see her anywhere.
- The prologue of Max Payne has Max telling someone who just called his number to call 911 because someone has just broken into his house and his family is in danger. The lady caller's response? "Good. I'm afraid I cannot help you," followed by her hanging up. Though Max does try to save his family, it's of no use, as both his wife and his baby girl get killed by the junkies. It turns out later that the lady caller was Nicole Horne, the Big Bad of the game, who sent the junkies to Max's home for the express purpose of killing his wife to keep a major secret from getting out and was calling to ensure that the job was being carried out.
- In Silent Hill 2, Laura, a little girl, locks protagonist James in a room with a boss monster. She has no idea that such a threat is even there, and is simply being a brat.
- Nebula: Both Mars and Uranus are extremely dismissive of Earth's steadily increasing fear and requests for help as a meteor hurtles towards her, with Uranus outright walking off and leaving her there alone as it's about to crash into her. In fairness to them, it was the first comic and there was some Early Installment Weirdness, with Mars gaining a heart of gold later and Uranus never showing that much detachment and apathy towards other people again.
- In the My Little Pony: Friendship Is Magic episode "Wonderbolt Academy", Rainbow Dash's partner Lightning Dust decides to whip up a tornado to help them score more points on a cloud-clearing exercise, even though they out-score the other teams several times over. The tornado not only throws around and endangers the other teams, but also demolishes the Twinkling Balloon, sending Dash's friends (who were making a surprise visit) plummeting to their doom. After they are rescued, Rainbow Dash calls Lightning Dust out on what she did - and she responds, "Yeah, and?"
- In Real Life this is a common phenomenon in cities, wherein no individual in a crowd wants to step forward and get involved with someone else's problem. People have been mugged, raped, and even given birth in broad daylight on crowded city streets while being completely ignored. Some experts advise that instead of yelling "RAPE" or "HELP," which receive disappointingly low responses, the distressed should yell "FIRE!" Apparently crowds are less callous towards a conflagration than a confrontation; it's almost certain to draw immediate attention.
- Another way to counter this is instead of yelling "CALL THE POLICE!" at a crowd, you should point to a specific person and say "YOU! Call the police!" since in the former circumstance's people are more likely to be afflicted by the Bystander Syndrome.
- This is called "The Bystander Effect" - The Other Wiki has an article on it here..
