Why on earth would there be a link between martial arts and redemption? And who exactly decides what redemption is?
You got it in a nutshell. If you want `redemption' for some crime you committed, you start with the person or people you injured. If eventually they come to forgive you---and there's no reason to expect that they will, if you really damaged them---then you can start trying to repair the damage you did to the larger society. I don't see how learning to use an armbar across someone's throat to force them to the ground is connected to healing the injuries you inflicted.
