I fully agree that restricting tadpole powers to an evil path, or at least evil actions. What I don't agree with is restricting the emperor/dream visions. The dream visions are the main narrative way we interact with the tadpole, which is the driving force of the narrative. I don't think we should be able to avoid the emperor. Yes he should be far more interractive and responsive to our PC's actions, but we shouldn't be able to ignore him. I think the game's problem is that we currently can ignore far too many things that should be baked in parts of the narrative. Not being able to interact with the emperor and by extension the tadpole would be like if WotR let you choose to just not encounter the mythic powers at all. They're a central part of the narrative, and being able to create a relationship with them is the core of the game.
