Dub, personality disorders (like narcissism) are hard to treat. The first step is understanding that he has a problem, and is willing to treat it. He still has to own it, as would any sociopath or psychopath. I doubt that's not going to happen. AJ's problem is way, way beyond what Desanto has.
But the "good" news it that he could still be a CEO, or run for national office. We hire or elect narcissists, psychopaths, and sociopaths to leadership positions all the time. Dub, someday AJ might even be your boss or run for President.
Isn't that comforting?
