I think he's mentally ill....a narcissistic nightmare.

But his hasty "turn around"  from Tillerson and Haleys tacit permission to Assad, two days ago to pursue Assads own ventures..... to some noble concern for those little kids breathing out their last on TV with foam filled mouths....(which had it not been televised..I suspect Trump would have just passed on it) strikes me as evil....very self serving evil..suddenly he's the prince of peace....

Assad and Putin are clearly evil....demonic if you will and perhaps Trump is a lower grade evil....mixed in with severe mental health problems....but enough of his behavior often enough is so profoundly devastating to the poor and the vulnerable that I do think of him as evil..actually very evil....the "Father of  Lies evil".
