Does anyone here know of what the differences are in the brains of psychopaths? Are they missing something?

David T. Lykken proposes psychopathy and sociopathy are two distinct kinds of antisocial personality disorder. He believes psychopaths are born with temperamental differences such as impulsivity, cortical underarousal, and fearlessness that lead them to risk-seeking behavior and an inability to internalize social norms. On the other hand, he claims sociopaths have relatively normal temperaments; their personality disorder being more an effect of negative sociological factors like parental neglect, delinquent peers, poverty, and extremely low or extremely high intelligence. Both personality disorders are, of course, the result of an interaction between genetic predispositions and environmental factors, but psychopathy leans towards the hereditary whereas sociopathy tends towards the environmental.

It is possible that some parts of the brain of a psychopath are different, and if you take a look at this link, it may give a clue, when you consider that it is normally considered that a psychopath lack a conscience...
