Justice?

I can't help but feeling that we live in a world that protects the provokers and punishes the provoked. If a guy talks trash to your face for hours and after a while you snap and knock him out, the man still standing is look at as a threat yet the provoker become the victim. It's like giving a child a spanking, he did wrong and now you physically discipline him. Or, if a man breaks into your home, armed, trying to rob you, and you beat him within an inch of his life, in his home and inner circle he's a hero, and the eyes of justice he's threat, while the man breaking in has become a victim. A man could save a woman from being gang raped, but accidentally kill one of the men in that gang, yet the woman will still have to beg and plead to get that man a lite jail sentence. But let the government be involved with giving the provokers what they deserve and all of a sudden it turns from assault and/or manslaughter into capital punishment.
