In one sense, all of the most vile despots in world history were “geniuses” in their ability, through their own toxic charisma, to gain a following of abjectly loyal opportunists hoping to share in their power and glory, along with the con artist’s talents for deception and manipulation. Trump fills the bill; he is, by far, the most evil “genius” in my lifetime, and we must never underestimate his deviousness, which goes hand in hand with his boundless malevolence and pathological narcissism to form the “dark triad” personality type he shares with history’s worst villains.
