Moral Quandary: Part 1 of 2

As you can tell I have been posting on tons of different random stuff. Now, onto a moral question!

Let's say that you have the choice of yourself dying or someone else (who you don't know) dying. Would you sacrifice the other person? What if the person was someone you know, but you don't find out who until you declare your decision?

Back to the unknown people—what if it's you or 10 unknown people? (If you would sacrifice yourself instead of the one unknown person, you can stop now.) What if it's 100 unknown people? 1000? 1 million? 1 billion? I sort of hope that you'd stop by now and sacrifice yourself. What's the exact number you would transition from saving yourself to sacrificing yourself? Would it change if you saw the people being killed? It really shouldn't, right? But in practice maybe it would.

Stay tuned for part 2, which should be a little more interesting.
