That genuinely depends, actually.

Narcissists are usually groomed all life and told they're special and extremely important and too valuable, so what can happen is that those people will feel like they NEED special attention OR to be the best, otherwise they're irredeemable failures, and they usually have very little (or a very fragile) self-esteem, AND they have insane amounts of self-doubt, self-criticism, or uh, just feel empty. That is what the majority of people with NPD experience. The "assholes" you see with NPD are the ones who actually managed to use their narcissism to get power over others, whether it be by having a child (and thus having power over them), becoming a boss, a successful capitalist, a teacher, or any of those other career paths that require you to have power over someone, AND were never told "no" at any point.

Also, there is no such thing as "narcissistic abuse". A disorder cannot be abusive by definition. People can be evil assholes WITHOUT having any disorders, in fact that's the majority of people who are assholes. Claiming "all those guys's evilness can ONLY be explained by them having a mental illness" actually does two things you don't want to imply: one, that they cannot control being evil, and thus, are excused of it because "it is in their nature", and two, it makes it significantly harder for people who have those disorders BUT are not evil people OR assholes to seek help.
