If there's one thing that gives me a tiny bit of relief, it's that narcissists are punished on a regular basis ... by themselves. They hate the kind of people they are so badly, but they can't help being who they are.
Imagine someone who wants to be proud of himself so badly and wants to think he really is number one in the whole universe, yet still despises himself and sees himself as a shit person, that's major suffering and torture for the narcissist.
