"A boy once said, 'I don't want to see people dying. Could it be possible,' he wondered, 'to save everyone in the entire world from suffering?' But what he was really trying to eliminate was himself, and he took up his sword for what he believed."This is essentially I Want My Beloved to Be Happy but in this case a character wants to erase themselves from existence/kill themselves because they think that it will make the one they love/care about happy. Heroic Sacrifice is when a character trades their life for something they honestly and reasonably believe is clearly worth more than their life, such as the lives of two people or to spare another a Fate Worse Than Death. In other words, the decision is based on valuing the lives of others over their own. This is when a character kills themselves or deliberately does something likely to result in their death because they believe others will be happier with them out of the picture. They're valuing the happiness of others over their own life. For example, if we put our characters onboard the Nostromo in Alien, and Bob attacks the alien, knowing he'll probably be killed but it will give Alice and Carl a chance to escape, that's Heroic Sacrifice. If he then discovers the alien has been killed by a falling piece of equipment, but decides not to rejoin Alice and Carl because he knows Alice will be happier married to Carl than him, even though he knows the escape pod is his best hope at survival, it's this. Compare It's a Wonderful Plot, where (as a Shout-Out to It's a Wonderful Life), a character gets to see what would have happened if they had never existed. As such plots usually prove, this sort of thing rarely makes anyone nearly as happy as the person doing it thinks it will. Failed attempts at this often result in the would-be suicidal person getting a What the Hell, Hero?, both for trying to kill themselves and for believing that the people they love would be happier if they were dead. Compare/Contrast Driven to Suicide or Undying Loyalty. Truth in Television unfortunately and let's just leave it at that. Contains Death Tropes so watch out for spoilers.

- The Kid Loki run of Journey into Mystery concludes with young Loki discovering he wasn't really an reincarnation of the original Loki, only an innocent clone of sorts, whom the original intended from the start to eventually erase from existence and take the body of, with his good name restored, in order to get back to backstabbing everyone whose trust Kid Loki had re-earned. Kid Loki is horrified- but Loki had also manipulated him into creating a MacGuffin currently causing a multiverse-endangering civil war that will only exist as long as Kid Loki does. Kid Loki ultimately agrees to be erased from existence so that his family- particularly Hela and Thor- don't get dragged down in the war and are allowed to be happy.
- In the James Bond film The World Is Not Enough, the Big Bad (or possibly The Dragon, it's not made clear) is willing to die in order to further Electra's plan to irradiate all her competitors' oil by blowing up a nuclear submarine.

It's implied that Tsukiko's opponent may have ended their competition this way.
- Sacred Sins by Nora Roberts: Joey is a troubled teenaged boy who is depressed, suicidal, and has dabbled in alcohol and the occult as attempts to cope with his depression, stemming from his mother's divorce from his alcoholic father and the fact that his father apparently doesn't want anything to do with him. His mother has remarried, the stepfather is basically the opposite of Joey's father, and the two of them have a baby. So on Thanksgiving night, after dinner, he sneaks out of the house, goes to a bridge, and jumps off it, convinced that his mother and stepfather will be happier without him and that they have the baby who can just replace him. He dies in a hospital, leaving his mother, stepfather, and the psychiatrist who tried to help him in tears.

Author Franz Kafka was not a very happy soul.
- Jude the Obscure: Jude's son and a Creepy Child "Little Father Time" commits suicide because the family is poor and he feels... Well, this was his suicide note: Done because we are too menny.

- MOTHER 3: In the final boss fight, Claus, Lucas's brother, finally comes to his senses. Then he fires an attack that he knows will be deflected back at him and kill him. He apparently did it because he thought his family would be happier without him, and that he should be with his dead mother.
