This is beautiful and I want to agree with you. Mostly I disagree that violence taints your soul permanently. I believe it is this line of thinking that has led the repetition of violence throughout history. Those who wish to do harm are never treated with strongly enough and so they persist. They are readily allowed access to others to harm as they please. Perhaps we can stave off states doing it with the right government types but there will be those in the general populace that desire harm for others and they will strive to upend that government at all times. My opinion is: oppression deserves reciprocal violence an order of magnitude above and immediately.
