Alckmin Luís Simone Grade 10 English Essay 2. Why Iago is a treacherous character? Iago, in Shakespeare's Othello, is a deceiving character because he tells lies in order to get what he wants. He interacts with people only to manipulate them, but most importantly he never reveals his true feelings or motives. Iago might say things that suggest what his motive is, but he soon contradicts himself with another suggestion making it extremely difficult to understand him. Although Iago's true motives cannot be determined, some motives could be jealousy, the enjoyment of seeing people suffer, or power. Iago's jealous of Othello and Cassio because he thinks that both of them slept with his wife, Emilia. In Iago's first soliloquy at the end of act 1, Iago says that Othello might have slept with his wife and even though this is a rumor, he says that he will believe it. Then in his second soliloquy at the end of act 2, scene 1, Iago reiterates and once again says that Othello slept with his wife, the only difference is that now he thinks Cassio has slept with his wife too because he believes that Cassio is a "proper man" and a playboy.
