Regarding the evil option, I feel it's a combination of class and dialogue - in the NWN Tortured Hearts (which I can't gush enough about, by the way), it was really difficult to go as an evil or morally ambiguous character because the diction and speaking manner was that of a naive 20-something. The HOTU usually had about 3-4 dialogue options which could take the good, humorous, ambivalent or scumbag path. Taking the evil path would usually be a thrill, as it goes against what the norms in the game are about. There is a sense of positive catharsis over screwing another character, without the profound sense of guilt most people would feel in real life.
Class is also a factor, but mostly because of the cliches established by other fantasy games. For example, there is rarely a final boss or classic villain who isn't some power obssessed spellcaster, and so there is that stigma of using a class where what they do in-universe is a bit more mysterious and unknowable than where to point your +70 Sword of Stabby Death.
