Lapis Tenembrae one seems half-and-half. The villainess, Claire, in "My choice is the villainess" is about 75% good and 25% bad, and her badness is her ignorance and how she was raised. In "Doom Flags" Katarina Claes is basically just spoiled and her only real evil is that when things fall apart around her she loses control and attacks the heroine with a knife - either she's stopped by Geordo killing her with his sword or she manages to wound the heroine, but then Keith kills her with magic. Her relationship with Keith is bad, too, but she's right about her fiance, Geordo. And if she were a generic genuinely evil villainess, then Katarina would fight the heroine for Alan or Nicol, and she doesn't even bother them. So all in all, Lapis is at least evil-er than most of the popular villainesses.
