The truth is that they're ideological zealots and cultists pushing a new religion. They know they have influence and are pushing to maximize influence through force as much as possible to reach their religious goals. Underneath that, the psychology of their personal lives is that they're some of the most miserable and useless losers to ever walk the earth, and exercising a never ending power trip is one of the only times in their entire lives that they'll ever feel alive.
