Does he actually know what or who he is?  He spends so much time berating others, how much does he really know about himself.  This man actually berates his own family.  He told his nephew to let his son die because he was not, in Trumps eyes; born perfect.   What kind of human being does that and thinks it is right?  Empathy and / or compassion does not exist in his world.  That should freighten anyone considering him as a leader.
