I don't think he's risking it again. I think that he's so far addicted to meth that he doesn't even grasp it any more. Addiction is so powerful. It's too powerful for some people. My cousin, who was in and out of jail for nearly 20 years due to drugs, has finally turned it around. He is in his late 30s or early 40s now, but got addicted like at 15 years old. In order to do it he had to move 4 states away and know absolutely no one and work conciously at it every day.
Even if it's not punch in the face, being pushed down adn into things and choke hold is like being beat up.

And not just in your body, because bones heal. But emtionally so, as well.

And emotionally wounds take much longer to close. It's not okay.
