Well, many would say that Akhenaten's religious policies where motivated by sincere belief, so I would take issue with that statement.
However, with regard to your first point, there seems to be an axiomatic disagreement between you and me. With regards to judging people's character, I do not feel it appropriate to base it primarily on their success. I do not believe that Ramses II was particularly motivated by altruism (he was a ginger, after all), so even if Akhenaten was doing what he did simply to have a power structure he more desired, and it was for his own glorification or success, then the thing which really distinguishes him from Ramses II is that Akhenaten's idea didn't work and Ramses II's did, rather than any apparent superior of the latter's morality.
I still maintain, despite his being eliminated now, that his being interesting is enough. Leaders in Civilization 6 aren't the most successful, some of them ended their reigns in horrible failure, but they're at least interesting or recognizable, both of which are traits of Akhenaten.
Fascist.
