He was a bit mental man, sort of like a chemical imbalance or something. I was a kid though, all I saw was a crazy kid throwing scissors at people.
If he became a Samurai, I'd say he would have gotten killed in his first encounter; rage rarely makes for an efficient fighter.
You surely must have avoided him. 😄
Truth about rage: it never allows for optimal thinking, therefore never producing the best outcome. So yeah, he'd have been killed long ago.
