IAGO: Thus do I ever make my fool my purse;For I mine own gained knowledge should profane,If I would time expend with such a snipeBut for my sport and profit. I hate the Moor,And it is thought abroad that 'twixt my sheetsH'as done my office. I know not if't be true,But I, for mere suspicion in that kind,Will do, as if for surety. He holds me well;The better shall my purpose work on him.Cassio's a proper man. Let me see now:To get his place, and to plume up my willIn double knavery. How? How? Let's see.After some time, to abuse Othello's earsThat he is too familiar with his wife.He hath a person and a smooth disposeTo be suspected--framed to make women false.The Moor is of a free and open natureThat thinks men honest that but seem to be so;And will as tenderly be led by th' noseAs asses are.I have't! It is engendered! Hell and nightMust bring this monstrous birth to the world's light. [Exit.](Iago's soliloquy, "Othello," Act 1, Scene 3, lines 374-395)

(translation)Therefore I will forever make money from Rodrigo; I will continue to gain from my knowledge and I shouldn’t speak against it, if I would spend time with such moron, I only do it for money and for fun.
I hate Othello, and it is thought in other countries that between my sheets, Othello is with my wife. I don’t know if it’s true but I will take it for certain. Othello trusts me; great now my plan to ruin his life will be easier. Cassio is a good guy. Let me see now: to get his place and not make much of a big problem out of it. How is it possible? Let’s see. After some time messing with Othello till he is too bored with his wife.He is too innocent but it is the other way around. Othello is an open minded person that thinks men are trustworthy as he is, he will easily be lied to just like an ass. That is it, I will do this and make it happen.
