I wasn't attempting to offend you, merely playing devil's advocate as best as possible. I didn't call you spineless, as I haven't actually seen you act in such a situation. Despite what I consider morally correct, I'm honestly not sure how I would act under such a situation.
"If it was necessary to kill someone, perhaps, us, as a species should die out." This is somewhat contradictory in that many people would have to die for us to die out. We are the only species that can appreciate morality, allowing us to be destroyed by it would make it contradict it's own value of life.
Well, there goes Godwin's law. Please elaborate in how killing one to save many can be likened to the events known as the Holocaust?
I again state that this is a hypothetical situation, and YOU know that what you would do saved the human race. Are you really so selfish as to allow the entire human race die out because you don't want your moral image tarnished?
