It would be too easy to start throwing out accurate descriptions of the guy. Sociopath, for existence. Except in his mind, everything he says IS the truth. As far as he's concerned, his actions ARE for the greater good. We are drowning in a world of grey, where "perception IS reality." Where do you go with that? I guess to be fair, the term "liar" should be reserved for the rare occasion when both houses of Congress, the President, and the Supreme Court are all in a room together; So that we wouldn't miss anyone.
