I agree with NP5491.  Don't take oiwi808's word for it.  

Take THESE people's word for it:

"“The Dangerous Case of Donald Trump” features more than two dozen essays breaking down the president’s perceived traits, which the contributors find consistent with symptoms of narcissistic personality disorder, sociopathy and other maladies. “Collectively with our coauthors, we warn that anyone as mentally unstable as Mr. Trump simply should not be entrusted with the life-and-death powers of the presidency,” Judith Lewis Herman of Harvard Medical School and Bandy X. Lee of the Yale School of Medicine write in the book’s prologue."
