Why do you think God creates psychopaths/sociopaths?

Countless studies have made it clear some people are born (or subsequently become this way after brain injuries) without the ability to empathize (sociopaths) with others and thus feel no remorse. Psychopaths meanwhile take pleasure in seeing others suffer and exhibit other antisocial behaviors. Why would God create people who simply could not follow his moral code? Did he create especially so they would go to hell?
