Haven't read the whole thread, but have you thought about telling him this:
"I'm willing to make a try, but don't expect to live long. We could let you play what you want to play, but you would be a double agent. You main goal is never to let the other PCs find out your true nature and you will have to go on with their plans until the end of the campaign where you will betray them in a planned way."
This could make things very interresting, if your player is not dumb. He could also be a primal species or whatever that someone on the evil side has decided to trust and so he does really belong to the PCs camp while serving a secret agenda against them.
