Evil is not well considered in SoA - although a bit better than BG1. To follow the path of Evil, one should get
better rewards than doing Good most of the time. Doing good should be harder to choose. You should have to sacrifice personal power, and wealth.
It can be fun to play evil, since in real life, the opportunity is invariably tied to causing trouble for others, which isn't acceptable. But there should have been some other approaches to stimulate Evil players-
Artifacts of Evil, which are valuable rewards: the equivalent of Carsomyr. Vampiric weapons are generally looked on as Evil. Poisons are usually Evil, and so on. Blackrazor was the exceptional Evil weapon in the game.
Maybe an alternative Stronghold? The goals of an Evil player might be acquisition of wealth, so maybe a Palatial setting? A Tower of Evil might be cool, for mages- stick enemies in there & torture them for power increases

Blood sacrifices for money and power should be possible. Why is it that we only get to kill monsters for money? Why not Merchants? Why not infiltration of their compounds, and slaying of their guards to get coin and magics?
Oh well. At least the Neutrals aren't complaining, and there was nothing for them
