Would you could you?

Sooooo, I have a question for all you readers out there (the two of you, yeah you know who you are). Would you kill one to save a thousand? I mean if there was only one way that this thousand could live was to kill that one person, would you do it?

Okay, good answer (or bad answer, or just plain old answer). Now if you said yes (or if you said no, or anything else for that matter) I have yet another question. Would you in fact kill a thousand just to save one? I mean if there was only one way that that one person could live was to kill those thousand people, would you do it? If so, who would that person be?
