You can’t concentrate on external things and status symbols and be happy. You can’t be happy and abusive at the same time. You can’t mistreat and manipulate others and be happy. That’s not what real happiness is about.
Real happiness comes from within, from a strong sense of self, from growing as a human being, from being a decent person. So if your core self is rotten, if you are severely disconnected, if you are not growing, and if you are a hurtful person, it’s impossible to be genuinely happy. The best you can do is desperately manage your shaky and skewed false self.
So what’s a malignant narcissist’s punishment? It’s their existence. It’s their inner prison. It’s waking up every day into their life that—despite possessions, power, and status symbols that they may have—they hate deep down. And then one day they die, and it’s all over. That’s the sad reality of a wasted and miserable life. And that’s their natural punishment.
