Hey, Sir K. Haven't seen you in a while. Sorry about getting the Imoen Romance forums closed and all.
Anyway, I think Bioware made a lot of mistakes in the alignment department, personally. I work from the assumption that Good is helping others when it is of no benefit to yourself. Neutral is doing anything which benefits yourself. Evil is any action intended to harm others that is of no benefit to yourself. As you can see, most creatures would be neutral - Especially creatures like mindless Shadows, and Wraiths.
Working on that basis, then, let's look at joinable NPCs.
The Evil NPCs: Korgan, Viconia, and Edwin.
Korgan, though exhibiting a more than healthy bloodlust, never suggests anything vicious/evil for no reason. Viconia, though having a 'colourful' past, similarly doesn't give many examples of causing others harm for no reason (apart from mentioning that she killed a number of her husbands "for sport", though, this is not sufficiently elaborated on). Edwin - His most "evil" trait would appear to be getting annoyed with everyone around him so much that he wants to blow them all up. Let's be honest, who isn't like this?
Hell, look at Yoshimo. He betrays you all to Irenicus. Yes, he's under a Geas. But, even at the cost of his own life, he could have warned the party. COULD have. He knew he'd die anyway. And yet he was put as True Neutral. Hmm. Little regard for his comrades.
Anyway if, upon rescuing any children from the slaver ship, any of these NPCs were to go "
Sod it, let's just kill the children", then yes, I'd class them as evil. But they don't. My suggestions for refinements, therefore, are
Korgan - Chaotic Neutral. Mazzy talks. Don't have him in long enough to write anything more.
Viconia - Lawful Neutral (Hard one to place - She's used to the law and structure of drow society, and used to following it, as the consequences of not doing so were dire - as she later found out. On the other hand, she has little regard for surface laws/structure, as shown in her candid account of whoring herself to Amn, and other dialogues. So, it's a bit of a toss-up between Lawful Neutral and Chaotic Neutral for Viconia.)
Edwin - True Neutral. He definitely holds the weak in contempt, and has no motivation to help others when he will not benefit from it. And he has what, at times, could be described as a truly individual sense of humour. But I think it would have to reach the point of him saying "I am bored. Entertain me by killing Garren Windspear and giving his land to Firkraag" before I'd class him as evil. Hell, he doesn't even try sell out the party to Irenicus at any point. The odds are clearly in Jonny Boy's favour, so I view this as quite a redeeming feature.
Oh, yeah, Sarevok. Er... hmm. Maybe, CE? Maybe?
Neutral NPCs:
Yoshimo: Hmm. I believe that even a self-serving Neutral
NPC would have some loyalty to their companions. Typically. But this isn't required. However... *Shrug* It's a tough call. Either TN, as he is, or NE. Though if he were NE, it would give the game away a bit, hehe.
Haer'Dalis: Now this one I agree with. He's a free-spirit, no love for authority or law, and motivated by his own whims. CN.
Jan Jansen: See above. Exactly the same as Haer'Dalis. Although Jan isn't a flaming bi. CN.
Cernd: Pisses me off too much to have him in the party for more than 5 minutes, so I'm not qualified to judge.
Jaheira: As people have said above... She's ALWAYS bitching at you to do good. Her alignment just doesn't fit her.
Good NPCs:
Anomen (If made a Paladin) and Keldorn - Well... assuming they believe the teachings of their church to be right... I suppose they should be put under "Good". *Grumbles* Damn annoying Paladins. So yeah, Lawful good for both. Otherwise, the alignments for Anomen are fine as they are.
Imoen: Wrong. WRONG WRONG WRONG. She should be Chaotic Neutral. She gets the soft spot for an underdog every once in a while, but as evidenced by A) The fact that she sticks with you no matter how evil you are and B) Her dialogue (and lack of it), she doesn't care THAT much. CN
Mazzy: I agree with this one. Though her lawfulness is slightly overdone, at times.
Aerie: Dear God. Well, if she could ever stop whining about her wings long enough to actually come up with some actions/an alignment, I suppose it'd be Neutral Good. She's too much of a tool to be anything but good, as she depends entirely upon her religion for the feeble strength of will she does have. And neutral because she doesn't really make references about her love for law/society very often.
OH NOES I HAVE LOST MY WINGS!
Valygar: What the hell? He's a surly prat. No different from Anomen once he's failed his test, actually. Especially when he starts fights with Viconia. Methinks he was only put as NG in order to be viable as a ranger. Anyway, Valygar should be LN, I'd say. Maybe, maybe CN.
Minsc: NEUTRAL good? NEUTRAL? He's goddamn insane! He should be Chaotic Good, obviously. CG
Nalia: Urgh. Neutral Good is appropriate, I suppose. Though it's debatable whether she is at all good. She's possibly just trying to 'help the commoners' because she despises her family and peers, and doesn't want to turn out like them, and yet doesn't actually care about helping the commoners. As shown by her
ToB "archmage" talks... Christ, I just psycho-analysed a
BG2 NPC. Jesus. Let's just call it NG for now, then. Until she goes power-mad and becomes a lich.
There. I think that's all of em. Sorry for writing reams and reams.
