I hear an ol MAist give an opinion, on that, and it has stayed with me for ages.
He said (not verbatim, long ago) - if me and a guy sized each other up, in a doorway, the "peaceful" thing for me to do would be step aside. But what if I knew he was walking through that door to kill the people in that room? Facing a predator is the same for me, could I give a mugger a couple quick shots and get away? Probably, but what about his next victim? A woman, an elderly person? If fate crossed his path with mine, I have a responsibility to make sure he hurts no one else. To me, that is part of the Warrior's Code.
Or something to that effect.
The problem is, for the most part, legally you're allowed to defend yourself to stop the attack. Once the attack is stopped, anything you do after that is considered assault (or worse). Once you are safe, anything else you do to stop the person from committing crimes in the future, outside of the law, is called vigilantism.
I would say that a choke is a lethal technique, because if you apply the hold correctly to get someone to tap out or pass out, you are applying the hold correctly to kill them. It will just take more time. With a punch, yes I can keep punching, but I have to keep connecting. With a choke, once I've gotten control, it's over.
