Uh, Seifer, that's the thing about child predators. They blend in. The creepy guys are very rarely the real dangers. Ok, to be fair, they might very well be serial killers or "normal" rapists. But child molesters learn how to blend in real quick. Don't for a second believe you can spot them for what they are. Plus child molesters usually target people close to them. The kids of friends and relatives. Or get into a pediatric field like preschool teacher or pediatrician. Disturbing, ain't it. Which makes Jackson too creepy to be a child molester. Insane, on the other hand, is perfectly likely.
As for Jackson's career, he's been surprisingly low-key about his music. Compared to other 80s pop stars (*cough* madonna *cough*), his ego is pretty low. As for a comeback, I don't think it'll happen. Could be entirely wrong. But his reputation is pretty much devestated for all time.
