I really like the nuance that Larian has brought to all the "evilness" stuff in BG3. The introduction of Viconia in BG2 (and the drow in general) was very poorly written.
From my perspective, I rock up to this group of people about to burn her at the stake literally just for being a drow. My only option is to let her be murdered or kill the crowd of bloodthirsty peasants. I rescue her and then immediately she makes it clear that no, she really is a remorseless murderer.
What? I think it's an pretty good twist on the "poor innocent woman about to be burned on the stake" stereotype.
