You can guarantee a random 10% of the world population all basic human needs, but you have to sacrifice a finger every time you make that deal; how many people will you help? - sh.itjust.works

The 10% stacks additively, each time you do the deal, this status is applied to a different 10%. If you sacrifice 10 fingers, the entire world is guaranteed basic human needs (food, water, shelter, clothing, healthcate, etc…) Nobody knows you saved them. Would you do it? — If everyone knows about the fact that you can do this deal, would that change your mind?
