Trump's type of psychopath normally comes to a bad end in a neighborhood alley. His father's wealth and criminal training allowed Donald to maintain a life style and erect a barrier of shyster lawyers to keep him safe. He has simply switched to a corrupt Attorney General but his mental plan has been scaled up but has not changed.
He wants everyone praise him or pay the price. His goal is casual genocide because he can't comprehend genocide. The whole world is his enemy and only his family should be saved. It's worse than you think.
Walking, COVID pneumonia with his preexisting conditions is a death sentence or, at least, complete debilitation. But, until he collapses he will frantically ramp up destruction to make himself feel better.
My fear is that he is aware that it is over for him and that will drive him to maximize human suffering while he can. The order to stop any COVID relief is a sign of that.
