Yeah, about that... https://www.giantitp.com/comics/oots1114.html

Hilgya has no moral opposition to setting settlements on fire, by her own admission. Here whole revenge scheme here also actively hurts other members of her clan that probably have nothing to do with decision making, some of whom could be very young, and she was willing to contemplate the possibility of just burning them all to death until she thought "nah, the smoke would be bad for my baby".
