There is no buts and nuts. By the time you decide to maybe shoot a second time he is on you. Fact.Well if a big guy comes at you with just fists and you have to shoot him I would shoot him once in the right shoulder and hope he stops and only shoot again if I had to and you would choose even prefer you kill the person. So thou shall not kill is not taken very seriously if you claim to be a christian. No?There's no such thing as "shoot to maim". Other than that you are babbling.
