Aspergers
The line "was led into a life of crime" is a much more relevant defence with regard to Aspergers.
As I have been diagnosed with it I can speak with some authority - someone with Aspergers is perfectly able to determine whether what they are doing in this sort of sphere is right or wrong. It is with dealing with people that we have trouble. I am aware that I can be described as naive and am easily led - I do not always understand that someone may be using me to their own gain. I also have to be careful what I do for others.
Due to the social issues Aspergers causes people who have it usually struggle to make friends (yet we want them). Therefore if someone is willing to be a friend for what appears to be a minor cost that cost is usually likely to be met so the sufferer is able to keep that "friend" - even people without Asperger's will do things for their friends which they know are wrong.
The issue with Gary McKinnon is that he didn't do it to keep friends (well, the reporting doesn't mention doing it for others).
In summary: People with Aspergers are perfectly able to tell right from wrong (and are usually strongly moral), it's just that due to social difficulties we can screw up priorities when other people are involved as sometimes the only way we can feel that we have a "friend" is when they are using us - but we're unlikely to realise they are.
