I agree, labels and descriptions for a race that has been around since the late 70's who are supposed to be the pinnacle of the Chaotic Evil Alignment, yet they only act CE when they are by themselves. Their society is much more that of an almost lawful environment. They are definitely evil, but I don't think they are LE, CE, or NE they encompass all three - which I guess could be labeled as Chaotic. Kind of a conundrum, then you have those that buck the evil label all together like the famous Drizzt.
I wonder if there's a differentiation between a societal alignment (all drow are LE) vs. personal alignment (this here trouble-making drow is CE).
Or that characters have 2 alignments, how they handle personal business, and societal business.
Thus, Caramon is CG with his personal life, but LG when it comes to bigger picture items.
I'll further accept that all humans have their hypocrisies. So it's totally OK to classify a PC with an alignment, where the majority of their behaviors fit, yet have situations where they contradict that alignment.
That is in effect, part of the introspection. When a character reaches a situation that conflicts with their common pattern, and they have to make a hard choice.
As to whether this introspection process is a good thing, consider that Drizz't and Raistlin were popular characters BECAUSE of this inner conflict and dialogue. That doesn't mean you have to make them all angsty, but the point of hard boiled detective fiction is that you get to hear this process the character is going through.
An extra ponderance. As a manager, when one of my guys screws up, the determining factor on what kind of talk I need to have with him has to do with whether they think they screwed up and are pondering how to fix it/do better.
I don't want my guys self-flagellating themselves, but I'd rather hear them tell me "for my part this is the mistake I made, this is how I fixed it, and this is how I think we can prevent it." If I hear "I didn't do anything wrong, it's all such and such's fault..." then I have a problem.
This is part of that introspection. If a paladin screws up, by whatever metric that means, a good paladin has regrets over it, and is seeking to make things right. A bad paladin won't think he did anything wrong. If you're wondering what offense to yank powers for, the latter example is your answer.
