I would never pull the trigger on two women in that situation. If they had a weapon.....even a stick or rock......then yes but no just throwing punches. I dont know if I could justify it in my own mind. Not that I would judge someone who did. I think it all matters how you feel in the situation.
I have seen what happens to families when a child is killed in that way. I lost a cousin to a young child while trying to help his drunk father get in his house. Shot climbing in the window to unlock the door. It was tough on his parents and would never want to be the one that took someones child no matter how screwed up they were. Now if I was in my own house and family was threatened.....done deal. Just me.
