His childhood is shrouded in mystery, as is most things about him. He keeps his secrets tucked away and only shows a fake persona to stay out of reach of blackmail and manipulation. This seems to help him immensely in his trade as both a pirate and a smuggler, and he makes a point to blackmail and manipulate others to flaunt his power of anonimity. So you could say no one has seen even one genuine moment from him. And in that way, no one can tell what he truly desires outside of money, power, and connections. But even then, no one can hold something above him- he has no qualms turning even those options down from time to time. This is how he stays safe. He has people who are loyal to him because of what he can accomplish, but no one can get close or keep his interest. A fickle man who is steered by no logical or moral compass.
