This is you talking past people again to push your uncharitable assumptions of my thoughts.
If it is necessary to end an immediate threat, then it’s okay. If you hunt someone down later that’s the vengeance and retribution I’m referring to.
I don’t want to live in a world where anyone with a deep enough grudge feels justified mowing down the object of their ire. Plenty of stories have explored this issue with revenge, recently it was The Last of Us 2 and I thought they did a pretty good job of showing what you do to yourself when you give into violent revenge fantasies.
It’s very disappointing that you’re so ideologically up your own ass that you can’t have a reasonable discussion with anyone. Automatically assuming the worst so you can rant about how depraved everyone but you is. Look in the mirror, get some self awareness, and go to therapy.
