In the dark mission, we had a choice regarding Ashan's fate. And the true, or rather the canonical, ending is considered the good one.

In this case, the evil and good endings are equal. The entire game is built around the idea that the Messiah must free the demons. But it is generally accepted that good triumphs, so the game has two options.

On the topic: I feel more sorry for Godric, as he was old and had done so much for the Empire.
Biyara's death didn't particularly please me, but it didn't sadden me either. She was just following orders. With Biyara, Ashan is much more interesting, much more complex (someone said that the world would be much simpler without her).
