The ironic thing is the game during Early Access did not have such a clear-cut line between good and evil as it does today. Companions were not goodie two-shoes but actual realistically behaving people given their circumstances, with fascinating backstories, trust issues and own intentions.
Karlach for example was not this lovely innocent carefree walking sunshine meme she is today, but a very vengeance driven bloodthirsty fighter that wanted to make the streets of Baldur's Gate overflow with blood as she was going after Zariel.
Wyll also was not this charming heroic idealistic goodie two-shoes either, but a very hurt and hate-driven man because of what goblins did to him, as he was chasing after Mizora to save her.
So the line was almost centered for the most part and Larian did seem to want to first focus on the good side before doing the evil side, but unfortunately development was rushed and all of their personalities basically became Disney-fied as the whole focus went towards the good side.
Despite countless of feedback being sent by the community about how lackluster the immoral actions are, as of today it is evident that there is no evil side. The game's narrative is clearly intended to perform heroic actions and any deviation from them punishes the player with less and less content as there is no longterm branching content from them.
On top of that Minthara went entirely ignored, as did the evil endings too. The fact that we did not get any epilogue, even a mere artwork showing what happens after is just depressing. I wrote about it myself for a Durge ending, but I agree. A disappointing one liner and fade-to-black is such a disrespect of the player's invested time in an evil playthrough.
