It’s a fumbly one, eh?

I agree that in an existence with that decision on the line, we would have to question many things.

Does someone innocent have to die, or is someone lying about the rules of the decision to save themselves? Would people who expect to kill this person be willing to offer same thing themselves? If not, why can they really decide for someone else? Is the death actually necessary, and how? Will new religions form from this?

What happens if it fails? Will that person just be dead for no reason? Will their loved ones be cared for? Who would even qualify?
