Knowingly lie every time he opens his mouth. Give as little shit about any life that's not his own as the presidents you're comparing him to. Treasonous and corrupt because it's his nature. Willing to sell America out. Capitalize on and encourage the worst in Americans. Violate and degrade women. Cheat on and cheat people... and there's more that with some certainty points to a willingness to throw any number of lives away to suit his very volatile, spiteful, greedy, gluttonous, malicious whims. He has an extremely narrow view of who doesn't classify as garbage people (Putin makes his non-garbage person list). Add that all up? He's too demented and dangerous to keep around to see what he might do.
Stop being a mindless tool, alright?
