I was stalked and repeatedly attacked by a bully growing up. I talked to a friend who had known this guy later in life, and he was the kind of guy who would do any stupid thing if he was challenged, or dared to. It was just his thing.
So yea, I'm sure he ended up the muscle for some petty drug dealer or pimp, and likely has toured the inside of several prison facilities by now. He was on that path at age 10 when I ran into him for the first time. And my friend described this guy as fuckin' dumb. Would do anything, especially if it was DUMB.
I don't feel any sympathy for these guys. I don't think they deserved death, but death found them anyway because they are ill-considered people without a lot of common sense.
