Yes he can be 100% bad.  I've known most of my adult life, long before politics were involved, that Donald Trump was bad news for everyone he touches.  No good can come from a truly morally bankrupt individual like Trump.  Yeah, the negativity is constant and I don't like it either, but the guy is big trouble.  As long as it was his private life, we could just watch from afar and shake our heads.  Now he's up close and personal and there's plenty of anti-Trump sentiment, for good reason.
