"Failure to Save" Murder

Say there are three characters, The Hero, The Child, and The Fool. Let's say that The Child dies in a tragic accident, for whatever reason, The Hero "fails" to save The Child in some way. Let's say that The Fool was very close to The Child. Even if the events surrounding The Child's death couldn't have possibly been stopped by The Hero, The Fool will have a lingering hatred for The Hero's "failure" to save The Child, sometimes to the point of outright blaming The Hero for The Child's death. Often used as plot motivation for The Fool.

Another variation is when The Hero is overcome with guilt, acting as his own Fool. The antagonist may use this against The Hero to psychologically torture him or her.

Anime and Manga

 * In Muhyo And Rouji,  joins Ark after the two executors she goes to for help in saving her mother from a haunt turn her down for petty reasons.
 * In Bleach, Uryu's grudge against the Soul Reapers stems from the fact that they had Soul Reapers watching his grandfather, and when he got attacked by Huge Hollows, didn't intervene until after his death. Uryu comes to realize that he didn't do anything to try to help his grandfather at that time, and that it's wrong to blame the Soul Reapers when his grandfather was not bitter toward them. Also, he has since discovered that the Ax Crazy Token Evil Captain Mayuri was the actual culprit, bribing Shinigami so that they would be too late and, worse, abducting the survivors (including his grandfather) in order to perform horrific experiments on them to satisfy his own curiosity (if by "curiosity" you mean "torture and kill them in numerous horrible ways for no obvious scientific reason"). He has thus shifted his emnity towards him and away from Shinigami in general (though he doesn't fully like of trust them either), though recently he'd been reduced to Mayuri's Butt Monkey.
 * In a filler episode of One Piece, a female member of the Desert Pirates remembers Princess Vivi and King Cobra visiting her city and promising to come help if anything happened, during which time she personally met a young Vivi. When the droughts hit, and Cobra didn't come to help, the city was deserted, and the girl was left in despair until the Desert Pirates recruited her. This caused her to resent Vivi upon seeing her again, but Vivi apologized, saying that there were many other towns requiring the king's attention, enabling the two to reconcile.
 * In Naruto, Sasuke's motives are based around.
 * In one scene in Baccano, Jacuzzi insists that Isaac and Miria should stop treating him like a good person because he's not -- he's fleeing from Chicago because he murdered three men. Donny interjects that Jacuzzi didn't kill them, his friends did. Against Jacuzzi's wishes. Because those men were about to kill him. Jacuzzi fails to see the difference.

Comic Books

 * In The DCU, John Stewart failed to save the planet Xanshi in the Cosmic Odyssey miniseries. John's guilt for this was extreme enough in the years afterward that one could be forgiven for assuming that he'd blown up the planet himself. The Xanshian warrior Fatality blames the whole Green Lantern Corps for the destruction of her planet, and went on a crusade to kill them all.
 * In this case, John's guilt isn't unjustified. He didn't just fail to save the planet. He knocked out J'onn J'onzz, who could have saved the planet. Stewart was overconfident and didn't consider the possiblity the bomb would be yellow and decided to "protect" the guy who is on par with Superman in power.
 * In WITCH, Ari of Arkhanta (a farmer who enslaved a banshee to become powerful) carries a massive grudge against the Oracle of Kandrakar. The reason? Ari's son was born autistic, and the Oracle isn't doing anything to fix this.
 * Superheroes in general tend to get blamed for whatever they couldn't/didn't do.
 * For example: Spider-man fights Green Goblin over Gwen Stacy, Spider-man lets Gwen Stacy die, Green Gobling gets Hoist By His Own Petard, and Miles Warren Go Mad From the Revelation and blames Spider-man exclusively and attacks him as his Split Personality Takeover villain The Jackal. To his credit, Miles Warren was Fighting From the Inside and when he wins, he realizes the idiocy of this and makes an Heroic Sacrifice to save Spider-Man.
 * Of course, a more legitimate example of this is a big part of the Spider Man mythos--before Peter actually became a superhero he let a crook run past him, only for said crook to murder Uncle Ben shortly afterward. His guilt over the issue is what drives him to become a superhero in the first place.
 * A random woman once berated Superman for being off-world during the "New Krypton" storyline -- while trying to stop a war -- while her husband was having an aneurysm. She thought Superman could have saved her husband with heat vision or something. Superman was the only person that actually took her seriously -- everyone else in-universe and out thought she was crazy to expect that from Superman.
 * In the relaunched Batgirl first issue, a cop screams that Barbara is a murderer when the villain kills someone and she doesn't stop him. Slightly more legitimate since it seemed like she was just letting it happen (she was actually petrified in fear, this being her first real mission since being un-paralyzed), but given that the real murderer was still standing right there it seems like the cop should have had other thoughts on her mind. (Commissioner Gordon, to be fair, calls the cop out on this in the next issue.)

Film

 * Nero's motive in Star Trek. The Fool is Nero, The Hero is, and The Child is.
 * In I Robot, Spooner plays the Fool against a robot who saved his life instead of a child because he had a bigger chance of survival. This caused him to develop hatred against all robots, arguing that the child's life was worth more and should have been prioritized over his regardless of the odds.

Web Comics

 * A variation occurs in Order of the Stick, when Redcloak in all seriousness holds O-Chul responsible for the deaths of several captives - when it is in fact Redcloak who is about to have them killed (or worse) unless O-Chul reveals a particular bit of info (which he actually doesn't know). Ironically, since to him it's clear that O-Chul would callously let everyone die just to protect his secret no matter what, he lets the captives live.
 * He then attempts to demoralize the captives by telling those prisoners to spread the word that O-Chul was willing to let them die.
 * Consider also how many goblins and goblinoids Redcloak has already sacrificed for his cause (including.
