I think an important lesson from Incubus is revealed from his phrase "to Rule". As he sees it Ruling is merely the same as walking away - Ruling is just like surviving as well. It is a distraction from winning. Winning, it seems like, means Winning - just like power means power from OOTS. If you are trying to win to Rule, or trying to win to Survive, or to win to Protect you are fooling yourself - winning is its own goal. As such, the way I read it is that for Incubus both Maya and Solomon are "losers" in the sense that their goal was not victory itself. Obviously, he is still trying to use her - but it speaks to his mindset and aim to restart a war and even let the universe be destroyed - he has no goal other than to win over everyone else and if the universe had to die to allow him to win so be it.
