An 'Evil' play through of BG2 is the single best way to show how to properly handle the Evil alignment I have ever seen in text or games.
They are all distinct characters, with depth, and history and motivation that is far beyond Chaotic Stupid.
The romance option there, blows anything in this game out of the water.
Honestly it's a meme to compare this game to BG2. It's not close.
