"Evil" playthrough in BG3 is just murderhobo behavior. Starting from main choice of act 1. I still have hard time to justify grove massacre as neutral evil or lawful evil character. Like why would you do that??
This is literal question Minthara asks you in act 3. Fortunately I was playing male drow- I answered that I did this to impress her, so at least it made some sense.
On my other run I just ignored whole conflict and moved on to moonrise towers, it felt much better.
