I don't believe Michael molested anyone(but dont know), he was completely asexual. Michael was an early form of what we see all over today, denying ones biology and just being whatever you feel you are, so he decided to be a 12 year old boy.
The summer when a boy turns 12 is a magical one. Just graduated grade school, into girls but not ready for sex. A great summer day when a boy turns 12 is going with his buddies to the skateboard park all day until it gets dark, getting change together for Gatorade and asking your mom to rent the MMA fight for the boys sleepover.
But its just that summer of 12 years old. The rest of your life you want to get laid and get paid. Its biology. Michael chose Peter Pan because he was 12 years old and non sexual. He viewed these boys as peers, not as a creepy old man, ironically making it just as creepy. lt was wrong, he was 52 years old.
But in his mind he wasnt. He wanted to permanently stay in the summer of 12 years old. .
