For the greater good

Another possible scenario for a self-sacrificing whumpee.

It usually involves a threat on a bigger scale than just their loved ones, maybe a city, a place full of people, the planet, timeline of History....

Whumpee may inflict some injury on themselves, in a way that will help save everyone else, or self-isolate with an explosive, or even keep doing something that increasingly hurts them. Ah, all the possibilities!

Not necessarily leads to actual death.
