Othello 2.1 "When the blood is made dull with the act of sport, there should be a game to inflame it and to give satiety a fresh appetite, loveliness in favor, sympathy in years, manners, and beauties; all which the Moor is defective in." (2.1 225-229)

I chose this quote because I think it further explains Iago's plot to ruin Othello. Iago wants to take revenge upon Othello and this tells us that he will build the strengths of his attacks based on Othello's weaknesses. He can now take advantage of Cassio's good looks and his attractive personality to lure Desdemona away from Othello and closer to Cassio. Even if Iago is affective and Cassio starts arguing with Othello, Iago can only be left blameless because he did nothing wrong so it is almost a no lose situation for Iago.

Why would Iago think Desdemona would be attracted to Cassio when it is clear that she is so in love with Othello that she would disobey her father?
