I don't know exactly how bad you can hurt anyone physically and get away with it if you do it in a very smart and proper way. Alas, most aspies probably aren't good at getting away with things, because we are socially "clumsy".
They always lay down more energy on getting a murderer than a person who has "just" bashed someones skull in. Also I don't know if I'd be going to prison or mental ward for such a crime. Theoretically I would get mental ward, but one can never be sure. And mental ward in Sweden is like a lottery. You can get decades or you can get out after a month. There is no time limit for mental ward for murder.
