I don't think TPJ is thick. I think he is full of rat cunning and he is on his behaviour, a real rat. He knows exactly what he is doing and he doesn't give a **** about the consequences on those who matter outside his thought bubbles. Sadly, he doesn't because I believe he is simply unable - see below.
Your analogy to Asperger's syndrome is interesting. People with Aspergers think instead of feel. If you talk to them about humility, they look it up in the dictionary and then substitute the dictionary definition for a real feeling. That is why they can't relate to emotionally to others, and why they can't conceive of the effects their behaviour has on others ... like his team mates, and the wider community.
I think conflating "being thick" with Aspergers is a bit wide of this mark, although TPJ does show signs of that illness (part of autism). People with Aspergers redefine the meaning of selfish. No amount of rational discourse will have any effect on them. Financial pain might but only in a superficial way. TPJ remains for me a sad case of a certified selfish prick, to be pitied more than crucified. Aspergers is a disease, not a choice, although his choices still wound those who care.
