that's an interesting take on it, though i don't see Gan as good or evil, but transcendent of good and evil. Gan is the World Axis - in his embodiment as the Tower - and thus stands at the center of the pairs of polar opposites [good and evil being among the categories]. Los is clearly representative of evil, no question about that, but I'm unsure whether I would agree that Gan represents "good." Still, you make an intriguing case.
