Your desire to murder is the answer?
If that is all you got out of my answers, there may be a certain amount of futility in trying to respond to you.
However...
No. I have no desire to murder anyone. That is not the point. The point is, I have a right to go through life without being attacked. If I am attacked, I have a right to defend myself, my family, and my property. Ostensibily, my defensive action would prove such that said criminal will never attack me again. If that means his death, then so be it. Do we really need to keep petty criminals alive to become even worse criminals after a life in and out of our legal system?
Is that what you really want? For that is what you are implying. that people should not retaliate when attacked. That they should just take it and hope the cops can catch up with their attackes later. How far does your idiot pacifism extend? Egging? Setting fire to your garage? Sexual assault? Torture? Terrorist attacks?
How far does your cowardice extend?
