I don’t know man. Ending a life though, you live with that.
Were you ever in the military? Haven't you ever deeply thought of the circumstances that you could be presented with in which you could take a life without remorse?
When I was nineteen out of high school I worked on a construction crew where the owner hired ex convicts. He would not hire thieves but he would hire killers that had done their time. At lunch one of them asked another one why he killed that man in a bar. The other answered, "he needed killing."
In spite of God's commandment, I know I could do it and I know I'm not the only human since the dawn of man that has been honest with himself.
I'm not saying I would have done as this homeowner has done. I don't think I would allow myself to live in a place like that, having been raised in a rural and small town life.
Ending a life? No big deal if you are acting in defense of you life and/or defense of another.
Too many TV programs and movies make it a highly emotional event. . .when it is not.
My son shot a drug smuggler that tried to kill him. Son was okay and proud of what he did, and rightly so.
Policy required three shrink sessions so he went. Thought it was a waste of time, after all, he was trained to do what he did, he did it correctly and was not bothered at all. The shrink, wimpy therapist required my son attend an additional session of therapy. Why, he asked, was told he did not show enough remorse for killing a drug smuggler. The therapist watched too many TV/movies that paint some silly picture that taking a life was an emotional event. Son saw it differently, as he was trained to do what he did, did it correctly and had no remorse. No call for remorse, he shot the bad guy that was trying to kill him.
What about soldiers? They go to war, shoot bad guys and come home. . .MOST do not suffer PTSD.
It is NOT something that you think it is (”ending a life and living with it”). Big deal. Living with it is the right thing to do. No remorse for a low life scumbag losing his life. . .I guarantee you that the scumbag wouldn’t have any remorse for killing you or your family
