Ninhursag seemed to not agree with things and was with Nepheline's side in terms of her opinion and her stand in the situation. Although she pitied the little Mist and would had healed her as well, she didn't thought that it was okay to get involved too much with these people.
Despite her having pitied the blue demon she killed; she still felt a lot of resentment against demons. Although not all demons had caused suffering to her, nor had taken away her family, she attributed a lot of the evil they committed against her and her family to all demons in general. It was something rather common within people's mentality to attribute the mistakes of some people belonging to an ethnicity to all the ethnicity itself.
