If you really want to label them with old-fashioned alignment, I'd say no companion is Lawful good, but none is chaotic evil either.
Thanks for the feedback.
Isn't Astarion at least a bit on the chaotic side, therefore bordering on CE?
Nah, I'd put him on a Neutral Evil side of an alignment scale. He is not a ruthless killer and he is doing evil things, if they being him closer to broke the bond with his sire. Plus, he is in this state for a long time, which made him treat others as lesser brings at some point. This is at least how i picture him do far. I'm still early in the story, though.
He is nowhere near as deranged as, let's say, Camellia in WoTR.
