He actually looks more faithful to his art now. Less charming man baby and more like a powerfull wizard you arnt sure is evil or not.
Uh, he's Neutral Good.
That make no sense. His actions is evil. Sure he may advocate for OTHERS to not eat babies, but if he could FORCE Mystra into his bed by eating babies, he would not for one second see anything wrong with it. Neither the forcing of a woman or eating babies.
He is a psychopath who says the right thing, to manipulate. Astarion and Gale is two very broken characters, but Gale is way more evil than Astarion. Asterion is just "your" fool brother that make bad choices, because he think it's "fun". Where Gale constantly try to gain power and when it goes wrong and make him a walking-talking living bomb, he keeps on risking everyone's life.
Shadowheart is not all that Shar like in actions, so who knows. Laz seems to be a kid that got taken away from mommy and daddy a little to early and doesn't seem to actually do anything "evil", maybe more a Lawful Neutral rules follower. She doesn't care about right or wrong as long as someone else control and tell her what to do.
