The narcissist believes that everything belongs to her, and if someone has a little of it, then she's not getting all of it.
Pathological greed, entitlement, and covetousness are what makes the malignant narcissist a dangerous predator.
They are forever out to take, keep from, destroy and besmirch whatever they can get their grimy paws on: be it your job, you home, your relationships, or your reputation.
It is sheer malevolence to be hostile to others getting what makes them happy and feel good about themselves.
And, it is beyond sick to have ill will toward people who aren’t harming you, have never harmed you, and have never threatened to harm you.
Malignant narcissists are pure evil. Just look at who they target: vulnerable children, people who love them, family, and the innocent.
