Innocent because of Asperger's?

I was watching an old E! special about billionaire murderer [Robert Durst] or something, I wasn't really paying attentions until the trial of a man who had murdered and disembodied a guy, then threw his remains over the seawall in Galveston. It first caught my attention because the crime took place in Galveston and I am from Texas. As the story continued the crime turned from horrid to just plain bizarre. This man was a billionaire who was living in poverty down in Galveston. I don't remember why really but I do remember that when sentencing came he was proved NOT GUILTY of murder due to the fact that he suffered from Asperger's. His defense attorney claimed that he couldn't feel empathy, remorse, sadness, therefore he didn't know what he did was wrong. Later he was proved guilty of Tampering With Evidence, that would be the disembodiment of the person he killed. To me that just seems a little messed up. I personally don't think Asperger's is an excuse for evil. While there is therapy and stuff like that for Asperger's, you can't fix evil. And I don't think it's fair to blame it on Asperger's. Plus it might send out the wrong inclination of Asperger's to people who know nothing about it. -------------------------------------------------------- Editors Note: Here's a LINK more about this man.
