After I got out of a relationship with a malignant narcissist, I realized that everything they do and say is a power move. They live in a world without objective reality. They cannot tell the truth because they function for a delusion. While you are thinking that you're having a conversation sharing ideas, they're observing you up and down to measure your strengths, weaknesses, social power, and threat to their social power. They listen intently to create a character they will present to you so that you enmesh with them. They run little secret experiments to learn how you react to things. Once they've figured you out, you're going to have a bad time. The sad thing is that underlying all this, is that they feel deeply insecure. They confuse envy for love. The more of an asshole a malignant narcissist is, the more they're telling the world they're insecure because the more they want people to envy them, which means the more they need love in their delusional world. Trump is extraordinarily insecure.
