Possibly, but I think its because Larian overpromised and underdelivered.
When EA started they specifically said they put in the evil companions first so that people play them instead of choosing only the good ones. And initially they were a lot more ambigious and according to datamining Nightsong was a very different person.
But late in development Larian seemed to realize that they can't deliver half of what they promised or otherwise decided to radically change the game. That was when the large rewrites began.
Additional origins like Minsc and Helia were scrapped and Minsc shoved into the back with hardly any content as they had to include him. The existing companions got rewritten to be a lot nicer and Daisy, where you had choices, got replaced by the railroad emperor where you had only a single path which was easier for Larian to implement. Any alternative path like Orpheus or removing the tadpole got removed and the evil path ignored completely.
I bet it wasn't even planned that the Durge is customizable, but because Dragonborn were finished so late they had added the option to create the Durge as a fall back solution if Dragonborn were not ready for release.
Tbh, getting rid of Daisy as it were, was a good thing for me. That touchyfeely thing going on there was uncomfortable.
And I'm still mad about Helia, she sounded interesting and awesome. And she would have brough ta bit more diversity into the mix.
I didn't dislike the Emperor, he was pretty good as a character, right until the point, he crashed Wylls quest to make the most unbelievable announcment.
What I didn't like about Orpheus versus Empy was the fact, that no matter what,
your character had to be the one to change - or Orpheus or Karlach. Lae'zel, who wants Orpheus to save her people is standing right there and yet says nothing about taking it on herself to change. I'm not turning for your space Jesus, lady, sorry.
I do hope, that they don't give us such a half finished end choice in the new game.
