Psychopathic James Bond is one of my favorite headcanons. I'm no medical specialist, so let's say I see him as a "movie type" psychopath.
His emotional range is close to zero. Bond is not easily impressed. How many times he almost died, and yet he always carries on as if nothing happened. Might also add his unbelievable pain tolerance to the list.
Bond is a high-class liar and uses it to his advantage. His conscience lets everything slide.
He's not empathetic. At all. He's spared people in the movies, but it had nothing to do with mercy. Just raw rationality.
Bond doesn't listen to anyone but himself. So many times he dodged MI6 orders to have things his way, often reckless and too violent. Thanks to him being a main character, his plans always work, and it feeds his huge ego.
Despite everything, Bond blends in very well with other people and you wouldn't know there's something wrong with him unless you get to know him better (and that's luxury that very few people can afford). His egocentrism makes him stand out, but no one really cares because he's got charisma and charm on his side.
Bond can't have healthy relationship with women and uses them either as sexual objects or sources of information. His partners change in a snap of a finger. Even if he can experience attachment, it's purely platonic. The closest he ever got to love was when he met Vesper, but Bond doesn't love her per se because he's not able to do that. She was his best friend, the person who understood Bond better than anyone else. Sadly or not, Vesper saw what they had as true feelings. Not sure they would make a functional family.
Bond is also attached to M, but, unlike Vesper, it has nothing to do with her as a person. M symbolizes his life duty, his service to the United Kingdom. Bond lives for that only, and he would fight for his principles until the end, so naturally, he would fight for M. People say she was a mother figure to him, and I don't think it contradicts my point. It's his motherland he's protecting, right?
According to Raoul Silva in "Skyfall", Bond failed his psychological test. Even if he wasn't given a specific diagnosis, he's canonically mentally ill. I think it's one of the reasons M keeps him around. Bond is no danger to common people, but his deranged mind needs to be occupied- and it comes in handy when dealing with criminals.
