Here's the deal. No one can harm another person. It doesn't matter who was hurt worse or who started it. The law applies to everyone. The only defense is that you had no alternative to defend your life. If someone clocks you, you sue them. Nothing in the law allows retribution, outside of legal consequences. Getting back or defending yourself simply opens you up to the same legal liability as the guy who took action first. The only difference is that there are now two liabilities, whereas before there was only one.
Just something to think about. There is no legal honor in defending yourself.
