I agree pax that the moment you start carrying a ccw, let alone draw it, you should be resigned to the thought of killing with it. While I respect your experience with firearms and see this as undeniable truth, I may have a little more insight into what happens to humans after they kill another human. In 20 years of spinal cord and brain injury rehab nursing I saw hundreds of veterans as well as normal everyday joes off the street after they had killed someone. In most cases it mattered surprisingly little whether the other persons death was justified, it was still devastating. A huge number of veterans ended up with us because of their substance abuse problems led to horrible accidents. I'm not shooting his knee for him, I'm shooting it because I know for sure what it's going to do to me. That being said, me or my loved ones dead, or me carrying a burden? Easy simple decision.
