My opinion is that using lethal force is the last thing you want to be forced to do.
Forced? Yes, forced to do by the other person's actions. Those actions could be directed at you or another person such as your spouse, child, parent or neighbor.
If I have to employ lethal force, I want to use the minimum number of shots that will stop the threatening actions. If, under stress, I fire one or two shots and the threat ends, that's all I need. If I need to fire more to stop a determined attacker, I'll do what it takes to stop the threat. The exception to this may be if I'm already down and taking injuries, in which case desperation may run until slide-lock.
