“How am I, then, a villain To counsel Cassio to this parallel course, Directly to his good? Divinity of hell! When devils will the blackest sins put on, They do suggest at first with heavenly shows, As I do now: for whiles this honest fool Plies Desdemona to repair his fortune, And she for him pleads strongly to the Moor, I’ll pour this pestilence into his ear,— That she repeals him for her body’s lust; And by how much she strives to do him good, She shall undo her credit with the Moor. So will I turn her virtue into pitch; And out of her own goodness make the net That shall enmesh them all.”
