A Moral Dilemma; A father's agonizing choice

A Father's Agonizing Choice

You are an inmate in a concentration camp. A sadistic guard is about to hang your son who tried to escape and wants you to pull the chair from underneath him. He says that if you don't he will not only kill your son but some other innocent inmate as well. You don't have any doubt that he means what he says. What should you do?

If I had to pick one of these choices, I believe I would take the first choice. I am his father, he's my responsibility. Therefore, I would be the one to pull the chair, as he is my responsibility, and letting someone else die because I shirked my responsibility would make me an even worse person. I may hate myself afterwards, but at least I'd only be responsible for my son and not for the death of someone who could've been freed in the future.
