I have followed threads about the same subjects at other websites, and I always find it funny how people try to extenuate their words by saying that you could save many lives with a million dollars. Of course, in theory this is right. You can save more than one person with 1,000,000$ and you only kill one, so why not?
But that isn't how it works. In the end you wouldn't give all the money out, and even if you would that wouldn't make up for your deeds. Whether you believe in a God or not, it isn't up to you to decide who shall live and who shall die. You can't take the law into your own hands. It makes you a murderer, regardless what your intentions are. If someone pushes the button, and you see you see a family member die, how would you react? Would your first thought be that the murderer will hopefully use the money to save others?
