In the Manhattan flashback, one of the soldiers said something along the lines of “When the ogres rip you limb from limb, pray that they are quick”. I doubt the ogres would suddenly be considerate just because they are faced with a woman.
Oh, that’s just war propaganda.
Hmm… We don’t know much about ogres. They can be violent, but they’re probably fighting for the survival of their species; creatures that big have a perilous position in the food web, especially when humans start changing the landscape.
