If I shoot, even in my own home in the anti-citizen People’s Republic of Maryland, I will shoot to stop the threat. That may be a head shot on a target that is standing still. It may be two in the chest and then one in the head on a moving target that will hopefully be slower when I get to the head shot. But my goal is to stop the threat, nothing more. Certainly nothing more that I would verbalize.
The entire process - anything you did - should have started and ended with “you feared for you life and what you did was to protect it.
