I think they hint at Kahga being evil. Shes the "serpent" druid and all. I mean when you first meet her shes torturing a child, so yea, not your typical druid for sure. I feel like shes the real evil path, like the "lawful evil" path if they were to actually get the paths right. Minthara is a psycho... Kahga has a Game of Thrones Cersei Lannister vibe... at little less smooth but about as coldhearted. and when you think about it, a serpent is cold blooded
