It's been a while since I've seen the movie, but wasn't the woman in charge of the humans pretty dang villainous? She had a motive, sure, but was pretty unreasonable in the face of evidence she was doing harm to everyone
I think she felt good about doing right by her people, to the detriment of the wilderness. Folks like the lepers who would've previously been outcast were given a home and purpose under the lady. Similarly, women of the village were also empowered under her rule.
