I never heard anything about that, so I looked it up. You are right. And Wahlberg didn't beat up just one person, over time he beat up many people.
But now he's got his life together. He is now a wonderful person, and he says wonderful things. But there is one small problem. He hurt some people really, really bad. I'm sure those people are in pain to this day.
I read some interview where the reporter asked Wahlberg if he ever tried to reach out to the Vietnamese guy he blinded in the robbery and try to help him out financially.
Basically, Wahlberg's response was that he hadn't and he didn't feel the need to. He had made peace with himself. He forgave himself for what he did to that man, and that was enough.
