I remember there was this quest in BG2 with the circle of druids. Same shit, druids going crazy killing everyone around them. Not sure why they were doing it but if i forgot why it must have been something among the lines of ' we are baaaad". The only difference being kagha doesn't kill innocent people. She needs someone else to do it for her. And tbh no one knows if they are innocent.
Mfw BGIII whitewashes druids.
