It's really not as simple a question as you seem to think. For one thing, I can't even answer your poll because there's only "yes" and "no," but no "maybe" or "I don't know." Whether or not I'd ever seriously commit myself towards harming another human being really depends on the situation. Would I fight in Afghanistan or Iraq? Absolutely not. Those are both wars that were supposedly started for the sake of defending my country (I'm American, if you haven't guessed). Would I, even if US soil was being invaded? I really don't know. I was raised with the principle that adults solve their problems with their words, not violence. That being said, I've never so much as been in a fist fight, because I've always been able to avert such situations. So...I really don't know how I'd handle myself, if I felt that I were being seriously threatened.
