זה מזכיר לי את הtrope שנקרא 'the women are safe with us'
"The tendency of movies to depict the villain's associated armies, tribes, barbarian hordes, and bands of mercenaries as being prone to raping the women of a town they're overrunning, while the armies, tribes, barbarian hordes, and mercs that are working for the hero are usually innocent of this particular atrocity."
"In modern times, it would preclude all audience sympathy to portray a heroic character as having a tolerance (or even worse, a taste) for forcing himself on captive women. A protagonist may have other character flaws; may plunder the enemy's gold, burn the enemy's crops, torch the enemy's buildings, or visit bordellos, but in most stories, there will be no rape or tolerance of it in his outfit. Rape will be forbidden, and malefactors will be dealt with."
"Movies that involve historical generals, chiefs, or warlords will generally treat it as a given that they didn't tolerate such things, unless such leaders are the villains of the work. Sometimes the all-too-common occurrence of officers who did disapprove being limited in their ability to control their men will be shown, since it still leaves the hero sympathetic."
"Although we'd never tolerate it from a hero, rape remains one of the many depraved types of behavior we may expect from a villain. Villains being villains, rape while pillaging will still be the order of the day when the evil enemy soldiers attack a village full of protagonists, and will be used to underline exactly how ruthless and vile The Enemy is. Individual mooks might be above this, but an army full of them... not so much."
