My nephew has mellowed out over the years, now that he sees that in school, there are bigger kids than him. And also cause a group of girls bullied HIM once, so now he knows that girls are not as weak as he was falsely thaught.
His dad got his karma, he now lives with his 2nd wife, who cheated on him and got pregnant with another dude's kid. Which he now has to raise together with her.
He also lost the ability to move one of his knees when he "accidentally" shot his own kneecap when he was "just cleaning his gun" when he was having an argument with his 2nd wife about her cheating.
