Iago's plan

At the end of Act I, Iago and Roderigo are talking and Roderigo is very depressed for losing Desdemona to Othello. Iago tells Roderigo that their courtship was too quick, and they will break up just as quickly. He tells Roderigo to sell all of his land and collect the money. Roderigo agrees and they agree to meet the next day.
Iago’s plan is to break up Othello and Desdemona, while at the same time getting Cassio’s job. He figures that he will start telling Othello and Cassio and Desdemona are getting too close. Because Cassio is good looking and smooth, Othello will start to believe him, especially because Othello thinks so highly of Iago and trusts him with even his wife. Iago has decided to manipulate all of the people around him and he is sure that his plan will work. I think it will work because Othello will turn into a tragic hero, so something must go wrong. Iago does make a good point about how they fell in love so quickly and got married, that something is bound to tear them apart. In Act II, Cassio and Desdemona are getting a little flirty, so I can see something happening in the future.
