My brother is autistic, he doesn't do this because there are different levels of seriousness. He also has a higher IQ then anyone at his high school, including staff. Serious Autism is comparable to being trapped in your own body. Think of sitting in a cutscene with your character doing something you don't want, you can't stop him. It's not being defective, it can be caused from trauma or birth problems. Trauma meaning being shot, run over, or hit hard enough. Most cases are trauma.
