Guess my reference wasn't clear enough: I was suggesting that you'd lose credibility to teach self-control.
I guess it depends on what you consider self control. That guy's brother for example, thanked me for exhibiting self control for obviously not doing way more damage. He looked at me like I could have literally killed his brother if I wanted to. No permanent injuries, but he learned a valuable lesson and never bothered anyone ever again, according to his brother. But hey, if you don't approve, then ok. I don't live for your approval, so it's ok with me too.
