There is never an excuse for unprovoked violence.
To physically attack another human being because you don’t like them or you get angry is to ask to be stopped in any manner someone decides to stops you.
Even Jesus said to “Do unto others as you would have done unto yourself.” If you attack to show power or act out aggression in anger, I can honestly say that I have no sympathy for whatever brutal outcome befalls you. It may be shocking and sad but very predictable. So many mock Christ but he also told us to love our enemies so we don’t retaliate against the ones that do act out or this world would be a non-stop blood bath of vengeance. Look around at the evil ones that provoke others to lose their souls daily defending themselves or others.
Self defense and acting out in vengeance are two very separate things, but can be confused in the human mind. It’s easy to want to get back at someone that harmed or wronged you, but It’s understandable if someone is beating you or someone else, that you try to stop that person, hopefully without killing them.
There is no one on God’s earth in their right mind that will sit back and allow someone to try and take their life and limb from them and do nothing to defend themselves or others if they are witness to such. We do have survival deeply wired into us. Even if someone is on your side or downplays what you do, because they don’t like the person or people you attacked and find a way to defend your evil act, it still does not absolve you of your guilt and blame for any incident that you started.
I loved the original movie “The Day The Earth Stood Still” for that reason. They had robots that kept all aggression under control on their planet and came to earth to warn them to knock off all violence or the planet earth would be eliminated. I really believe that if mankind does not get the “devil out them” real quick, with the current technology we now possess, it would not be hard to destroy the planet and everything God created.
