It's another example of Mr Shakespeare pandering to his audience's baser instincts.

Oh, I don't know. Maybe the highblown passages were a sop for the Jacobean intelligentsia, so they wouldn't feel so guilty about enjoying all the sex and violence. Come to think of it, they wouldn't have had a problem with any of it. It took later generations to tut-tut and tsk-tsk certain passages in WS' texts. Reminds me of the folks who wrote new libretti for Così fan tutte in the 19th century, because they couldn't stand Mozart's divine music embellishing whorish words.
