Fan Casting Heroic Suicide in Sort by Tropes

This trope is about situations where suicide becomes heroic. Say a character discovers that he is a Person of Mass Destruction, a crucial part of an Evil Plan, or the Big Bad's Soul Jar. In such situations killing oneself may be the only way to save the day. This is a specific sub-trope of Heroic Sacrifice. The difference is that in most Heroic Sacrifices dying is merely an unfortunate by-product of a heroic act. In a Heroic Suicide, dying is necessary to perform the heroic act. Or, to put it another way, a Heroic Sacrifice engages in heroic activity even though it can get them killed. A Heroic Suicide engages in heroic activity knowing that it will get them killed.
