I disagree. Particulary, I think old-school men (as in BIBLICAL) knew the nature of women (that they are normal people, and normal people are fucking bastards). That's why things were how they were. Slowly, we lost sense of that of the chivalry, but the concept of the good girl falling for the bad boy is REALLY old. Like, King Arthur old.

From memory (haven't read this in a minute), Arthur was a pure white knight in shining armor who represented all of good in this world. His wife and Lancelot were fucking each other silly while he violently insists to his friends who are telling him how fucked up his wife is she's still as pure as when they met. Same experience many "gentlemen" go through nowadays.

King Arthur showcases the naiivety of chivarly - Guinevere was pure, yes, but that was forced purity. She was locked away from men except her father until Arthur married her. Once free, it didn't take long to reveal her actual tendency was slut. Anyone who's pure by outside force has never been tempted, and so is a dangerous commodity. That SHOULD be one of the lessons of that chapter in the tale. If someone aint been exposed to the fires of lust, sure they aint been burnt, but they aint proven fireproof either. A maiden can be manufactured by her parents' control instead of her own will.

We knew in the beginning, but we forgot that women were only humans just like us instead of ridiculously pure saints, and that's when we fucked up. They're only human - our just-as-imperfect counterparts.
