Swen said all of the NPCs announcers so far are evil or neutral. Astarion is probably Evil, possibly Lae’zel (she is certainly mean). We haven’t seen enough of Gale and nothing of Wyll, yet.
I think Shadowheart is evil. Lae'zel I would probably say more neutral though, only concerned about her quest to defeat Illithids, no matter the means. Astarion definitely evil too.
