That could work, but I don't see much base for the sociopath's personality wishing to be a spy. Usually, they like attention, and their own people to manipulate. They'd prefer to send spies and be the one in charge. Unless, of course, they were spying on their own will. That and again, Sociopaths switch jobs quite often, and you can't really quit being a spy at any time.
Though, they could use it as a way to get power, I suppose, though I haven't heard much of spies gaining rank. But it would do, considering not all Sociopaths want power, some do prefer isolation save for their small group of people.
