A narcissist's need to "have it all," all attention - all regard, all glory, all praise - the need to have it all is the need to deprive others of any. When you deprive others of good things, to the point that you deny then even a pittance of these good things, as though you need to hoard every last bit of it on earth to yourself, you ARE a predator.
By depriving people of what they NEED - love, acceptance, regard, respect, a good name and so forth - you are denying them what all people need as much as they need the air they breathe.
You are denying them necessities of life to hog it all to yourself.
That is a hostile act. It damages those people you deprive. That makes you a predator, a plunderer. No two ways about it. Predators never identify with their prey. Predators dare not have any feelings for their prey.
This is what makes malignant narcissists and psychopaths so inhuman to their victims.
See Predation at the Main Site and in the book.
