Wouldn't surprise me for a second, I always thought Clinton was basically-good-natured but a mild sociopath* at root.
*A very large percentage of sociopaths are more or less functional in society, not the ruthless killers portrayed on crime shows, they just have no real empathy and have some level of impairment in connecting present actions to satisfy their immediate needs (From sex to status to adulation to consumer goods) with the future consequences when all the lies they told come home to roost. Their lives are a dynamic process of lying to get out of the last previous lie, with no real worry about the past or concern about the future, which they are unshakably confident they can BS their way through when it comes along.
