Have no problem with that! I’m talking about having to kill someone personally - a problem that exists with our servicemen. It is a problem and understandable... It can be a continuing problem and understandably so...
Oops. I mistook your post for a different one. Nevermind. : )
You can stop wringing your hands and wetting the bed. Studies show that justified killing leaves few scars, if any, whether done to protect one's self or others. But I find it interesting that you believe you'd have nightmares if you defended yourself, but not if you defended others. It's that kind of self-contempt that usually leads people into collectivist groups - the same kinds of groups which, historically, have led to the murder of more hundreds of millions of their own people than all the wars combined.
And THAT gives ME nightmares.
