Hard to tell, because if I consider the situation "me or you" as told by artist, saving myself and killing the other person would mean I consider my life to be more important than the other person's life. So there's no point in it. I'd say I could end killing another person for survival instinct maybe, not thinking about it, neither for a second. So, I really should find myself in the situation to tell (hope this won't happen, never!

). There's no way I can say my principle is "if my life is in danger, I could kill".
But anyway, with my life really in danger I would probably end being paralyzed because of the terror. This means I would be the one killed and not viceversa
