If it gets to the point where you're that afraid for your life shoot to kill. Center mass. You're past the point of trying to scare someone. Always remember that person made a concious decision to hurt and possibly kill you. You have no other choice at that point. If you choose not to then you may die. Simple as that at that point it's you or him/herYou could always think if you needed to shoot someone to shoot too high or too low. May be enough to scare the creep.
I got to the point that I was taking the roos to a vet to euthanize. I just couldn't use an axe or anything violent. Now I put a tube down their throat and tube 45/60 ml of vodka. Eventually they fall asleep and die. A lot of times I hold them till it's over.
People can think the worlds all good and "I could never do that" but theres really bad people out there and they do not care about a human life
Sorry just keeping it real
