Control.

At the root of needing to control people is fear.

And narcissists who try to control everyone are the most fearful.

Their sense of self is so fragile that they need to control what people think about them.

And their relationships are so insecure that they need to control everyone's behavior.

At the root of this is a deep existential fear.

A fear that they will not be able to survive if they don't control people.

And this extends to their attitude to money, status, possessions, power, and politics.
