In act two, Iago begins his plan to make Othello believe or at least get jealous of Cassio when Desdemona speaks for Cassio. Iago is using Roderigo to provoke Cassio when they’re on duty to stand guard. He makes Roderigo believe him by making seemingly sincere promise of helping him to get Desdemona’s love. On the other hand, Iago himself is trying to make Montano believe Cassio has alcohol issue. “…I fear the trust Othello puts him in on some odd time of his infirmity will shake this island. (Act 2 Scene 3 110)” When Montano suggests to inform Moor about this information, Iago then says “Not I, for this fair island. I do love Cassio well, and would do much to cure him of this evil – (Act 2 Scene 3 129)” Iago talk Cassio into drinking, and mislead Montano to a wrong impression of Cassio. He then acts nice to defend for Cassio by saying he would like to help his alcohol problem, and he wouldn’t sell him out to Othello even for an island. After Roderigo successfully provoked Cassio and made Cassio attack him and Montano, Cassio lose his position to work for Othello. When Cassio is down, Iago persuade Cassio to approach Desdemona because she is influential to Othello. “Our general’s wife is not the general… Confess yourself freely to her, importune her help to put you in your place again. She is of so free, so kind, so apt, so blessed a disposition, she holds it a vice in her goodness not to do more than she is requested. (Act 2 Scene 3 298)” He tell him, “I protest, in the sincerity of love and honest kindness. (Act 2 Scene 3 319)” Cassio took his advices dearly because he believes Iago is helping him out of love and kindness. Iago not only make every men he manipulate believes him, he also protect his own kind image in front of them. By looking closely in to his words to other men, he is telling each man different things privately to mislead them to benefit his own evil plan.
