I mostly agree with your post wheelz999, however not every person biology is the same. I watched last night Martin Bashir 2003 MJ interviews; Michael was clearly suffering from severe mental health problems. I'm no psychiatrist so I could be way off here, but I think most mental health problems are biological in nature. Yes, upbringing circumstances could exacerbated those problems, but not every sibling has the same biology as Michaels' so it's not surprising seen more adjusted siblings than other given the same upbringing.
