I like your feedback, thank you.
Though I do disagree with the emperor being evil.
He is by no means good at all. But he is not malicious as he is manipulating you, but it is not to anyone else's determined other than the Elder Brain.
He just doesn't want to die and be left alone
Thanks! I like your suggestion. I do think it would improve the game.
On the question of evil: I think the fact that's he's evil can be deduced from his actions - running the Knights of the Shield, destroying Setlmane's mind, eating people, enslaving Orpheus etc - but without that we have both an official WotC module and the Larian devs declaring him evil so it's pretty difficult to maintain that he's anything but evil.
Which is why I would much prefer a
satisfying boss fight. Freeing Orpheus should be a great moment for Tav. Finally she gets to turn the tables on her manipulator. She has gone through a personal journey like the one Myrina did: from the victim of manipulation into an agent.
But, again, I do think your suggestion would improve the game
