I have German shepherds. My life is good and I will not risk it or theirs by hurting other people. I would never put myself in a position to kill someone over a grievance. I value my own consciousness too much to throw it away on revenge. There is no afterlife where everything is fixed; when you are gone your consciousness is gone. That makes ending someone else permanently something I will not do.
There are plenty of people who deserve punishment, but we trade the right to take that punishment into our own hands for the benefits of living in a civil society. We give up the right to use lethal force as personal vengeance, the right to run our own private trials, the right to seize property or mete out punishment outside the law, and the right to resolve disputes by violence. In return we get policing, courts, prisons, public infrastructure, and stable commerce that let most of us live without constant fear. That trade is imperfect, but taking justice into your own hands destroys the thing you are trying to protect.
If you want to fix society, do it inside the system or build something better with your hands and time. Violence just makes more victims and ruins you and the people you care about.
