a single punch in the face can and has killed people in the past. Ive seen guys get punched 1 time and then never fully recover. I will not put my trust in someone that just punched me in the face. I have no choice but to think if they are willing to punch me, they are willing to kill me. I have no idea if they will stop after 1, 2, 3 hits. I don't want to find out either. I don't think you do either.
If someone hits me and I'm armed and feel my life is in danger, I'm shooting.
Don't hit someone. ever. Specially in this era of everyone carrying guns.
got it?
