I realize Autism is a neurological condition that is not curable. I work with children with Autism (powerlevel, I know, but I'm not talking out of my ass). However, it is possible to learn adaptive behaviors, teach a person what is socially acceptable and, for lack of a better term, train them. The earlier those interventions are started, the more successful the child will be. And I think that's what his first elementary school was trying to do by recommending he go to the school in Winchester. His parents absolutely made the wrong choice in raising him the way they did. They refused services and didn't do anything when their son was clearly going down a path that was not acceptable. The signs were there when he was young and even moreso as he grew older. They never did anything. Bob should have cut down the internet, he should have had consistent consequences for his actions, like any child, but it's even more important for a child on the spectrum. His parents had no idea what to do with him so they let him do whatever he wanted. It was probably easier than dealing with his tantrums, which is sadly the case for a lot of parents of children with Autism.
Chris is the exception, rather than the rule, when it comes to people with Autism. And to classify them all as transgender or man-children or school shooters isn't fair. The majority of Autistic people (on all areas of the spectrum) grow up to be fine, decent people who contribute to society or, at the very least, don't cause trouble. But how they are raised absolutely plays a role in how they turn out. So yes, I will lay some of the blame at his parents' feet. Just because you're born with a condition doesn't mean you're doomed to become something, with proper treatment, it's possible to not be an incestuous rapist so wrapped up in his own fantasy world he's largely lost touch with reality, who is so ruled by his own selfish sexual desire (because no one taught him that women don't own you affection or sex, that no one is just 'given' a girlfriend and that his LoveQuest was impractical from the moment he conceived it) that he fucks his own mother.
