I first said this sort of think about Clinton (or King Bubba I, as I preferred to call him). One of the jobs of a parent is to create "walls" for their children, to make them functioning members of society rather than sociopaths, sociopathy being the default human condition.
Some of the walls are for personal safety ("don't go running out into traffic"), some are for dealing with other people socially("don't, point, don't stare, and whatever you do, don't mention the giant mole on his neck!") and some are respcting other people's rights and property ("don't steal, don't break other people's stuff, don't hurt other people"). As a parent of autistic children, I can tell you that job is even harder if you're dealing with a child who is naturally predisposed to ignore or misunderstand these lessons.
Now, in the cases where the parent fails utterly (or parents, more often than not just one parent though), it's usually pretty simple -- the child is completely unable to function in normal society, and often forms part of the low levels of the criminal element. But for those who learn how to survive and deal with people socially, but do not learn respect for their rights, you can get the truly dangerous cases, because these people can be clever and charming. And they're often drawn to careers that put them in positions of authority over other people.
Clinton is one of these people. Just ask Juanita Brodderick. Obama is another, and quite likely worse. Because Clinton was really focused on self-gratification whereas Obama;s focus is on the acquisition of power and using it to crush those who oppose him.
My parents never taught me that one, and I've been paying a heavy price for it ever since.
