I think Michael's mental and intellectual capabilities are at the level of a child. He loves to hang out with children, as they
are his equal.
He is a child trapped in a man's body. What others might
find as odd behavior, like sleeping with other boys in one
bed, might be a childlike sleepover to Michael.
I'm not saying he is innocent, but his mental deficiencies
and abusive upbringing should be considered in this as well.
