The most important thing to remember about autism is that autistic people are still just people: we are all unique, individual human beings with our own unique personalities, characters, morals, and likes and dislikes, and of course different upbringings and childhoods and things that influence how someone develops as an adult.
I'm autistic and I personally am really not law abiding or rule abiding particularly, and I think I'm pretty good at getting away with stuff (I definitely believe that I could successfully plan and carry out a murder, though I would only ever consider killing someone who was extremely evil and I believed posed a grave danger to society) but I have a strong moral core and set of ethical values and generally a strong sense of fairness, which personally mean more to me than laws. I have deep empathy and I could never hurt anyone unless in self-defence or if they were hurting others, but stuff like, for example I gave my mum a pot brownie when she very seriously ill and in great pain. That's illegal but I don't believe it's unethical or that most people would consider it unethical.
I've read that autistic people tend to have a strong innate sense of fairness, maybe that's true I don't know, but personally I don't think you can generalise all people with autism because autism isn't someone's entire personality, they still have an individual personality separate from that.
Sorry I don't mean to derail the thread, I just think it's an important thing to say, because there's so many myths about autism.
