In regard to protecting one's own life or that of a family member, I've often wondered what goes through the head of the person who says "I could never harm someone in any situation." I don't mean this in a sarcastic way, I'm really curious.
Although it's an ugly and overly simplistic way to look at things, at the most basic level you can boil it down to assigning value to a human life. You can choose between:
1. A normal person (or child/spouse/parent/etc thereof) probably trying to lead a productive and good life, who is surprised and attacked for no justifiable reason.
2. A person who sees no great problem in attempting to end the life of another without provocation, and likely has done similar things in the past and almost certainly will in the future.
Maybe I'm being arrogant, but if I ever get put in a completely unavoidable situation where that choice must be made, I will likely decide my existance has more merit than that the individual attempting to end mine.
