There is a book by that name by conservative Rick Wilson and even before I read the book it I used the analogy that Trump is cancer in human form. Cancer, but definition, is only able to survive and thrive through the destruction\killing of healthy cells. Trump has operated that way his entire adult life, he uses, abuses, and takes advantage of people, places, and things until they are destroyed, or they manage to get beyond of his reach. It is who he is, it is what he does best. He does not know how to help people or build things, which is what a true leader does. Trump has zero leadership skills or leadership abilities, and he doesn't even have any true skills at destroying things, he destroys things by convincing others to, more-or-less, destroy themselves to his benefit.
The key to Trump's future downfall will be that he becomes more an isolated, even to the point where his family will decide to save themselves rather than destroy themselves for him (ie go to jail for him, go bankrupt for him, etc). If he is lucky, he will die in his sleep very soon otherwise at some point he'll be living all alone at Mar-o-largo, shut down, falling apart, in foreclosure, and be under federal indictment waiting for trail by a court appointed attorney because he is bankrupt.
