Imagine your reaction if someone pointed a weapon at your child.
A better rule in the civilian world would be to give a reaction proportionate to the provocation.Warriors can experiences moments of profound guilt, shame, and self-hatred.He may have experienced a momentary elation at “scoring one for the good guys,” then been horrified that he celebrated killing a human being.He may make an exception for his children (because they cannot divorce him), but that will be instinctual and he will probably not be able to explain his actions. This was true of our beloved “Greatest Generation” warriors of WWII, and it remains true to this day.
Technically, your warrior may well be a killer, as are his friends.
Every day I listen to my combat veterans as they struggle to return to the “normal” world after having a deeply life-changing experience. Sometimes that can involve medications, but listening is key.
