You've pretty much defined psychopathy and there is no doubt whatsoever that Hillary is a psychopath (as is Bubba). Unfortunately the vast majority of other high-level politicians are as well. Many astute observers believe the world is run by psychopaths and until that is realized by the public and acted upon things will never improve.
On the other hand, Trump is not a psychopath. He's a megalomaniac and that is not a pejorative when he's motivated by patriotism. He believes he is the one man who can clean up the mess and he's determined to try. Truth is, he may be the last man who can clean up the mess, and the odds are still against him even if he wins the election. But he's admirable as hell for trying.
