To get his place, and to plume up my will.
In double knavery- how, how? Let's see.
After some time to abuse Othello's ears.
That he is too familiar with his wife;.
He hath a person and a smooth dispose.
To be suspected, framed to make women false.
The Moor is of a free and open nature,.
That thinks men honest that but seem to be so,.
And will as tenderly be led by th" nose.
As asses are.
I ha't. It is ingendered. Hell and night.
Must bring this monstrous birth to the world's light" (1.3.368-85).
Another thing he said was: "O, you are well tuned now, but I"ll set down the pegs that make this music, as honest as I am" (2.1.197-8). This he said aside, when Othello was in a good mood and looked happy with Desdemona, because he did not want Othello to hear him. Iago uses racist comments all the way through the play, as he tries to turn people against Othello. All this is to help him with his plans. The more the people are against Othello, the easier it is for Iago to succeed in his plan. Still, he never says anything racist to Othello's face because in his plot he had to be his best friend, so as not to make him suspicious that Iago was causing all the trouble for him with the exception of the part where Iago gives Othello reasons why would Desdemona go for another man "clime, complexion, and degree" (3.3.235). This is another usage for the racism, but this time it is just a trigger for Othello's suspicions. .
For revenge of the rumor about Othello sleeping with Emilia, Iago feels that the only way to get even with Othello is to sleep with Desdemona "wife for wife" (2.3.286). If Iago fails to persuade Desdemona, which he do not even try to do so, he plans to convince Othello in a way or another that Cassio and Desdemona are having an affair. Iago hopes that this would make Othello jealous forever.
"For that I do suspect the lusty Moor.
Hath leapt into my seat, the thought whereof.
Doth, like poisonous mineral, gnaw my inwards;.
