People usually have to do things in order to live. They eat, drink, breathe, and do what's neccesary to live. But sometimes, there's more to it than that. Normally, people would kill other creatures to get the necessities of staying alive. And then, there are those just need to kill things to survive. Not get any materials or pieces of creature or other beings. Just klling them is what they have to do in order to stay alive in the world. There could be two types. Periodic. The character needs to kill once every certain period of time. They can't surpass that amount and any attempts would just keep them at a maximum. Limitless. There is no limit to how often the minion must kill. As long as they don't run out of time, they can get as much as they want. Subtrope of Trapped in Villainy. Compare Horror Hunger.
