Yes, you are. Or at least, I suspect you are.
If it were necessary to kill someone in order to be the one walking away from a fight, would you? If so, then you're in a life or death fight. Sure, at least 99% of the time you won't have to. But if you're willing to kill, then it's a life or death fight, even if you're in that happy majority of cases that provide more than just one option.
I don't have a stack of bodies (one quadriplegic, but no deaths), but if I'm in a real fight, then yes, killing is an option.
You like to act as if being willing to kill means you always do. And that's just silly. It's merely one of many possible results. And, generally speaking, the least common.
