Othello's IagoIago has no conscience. He is an angry man and is happy to tear down everyone around him to get what he wants: revenge. It is in Act 1, Scene 3 that he hatches his evil plan. Here we can see inside Iago's mind. It is easy to see that his main motivation is jealousy: jealousy that Othello may have slept with his wife, and jealousy that Othello chose Cassio over him. As he plots his revenge, it is clear that Iago does not respect or care for anyone. (Act 1, scene 3, 378-381) I hate the Moor, and abroad it is thought that between my sheets he has done my office. I don't know if it's true, but I, for simple suspicions in this kind, will do it, as if it were safe. Iago states here that he suspects that Othello may have slept with his wife. He's not sure, but he says the surety bond isn't necessary. I believe that Iago is not so much worried about his wife's betrayal, but that he cannot bear the thought that it may have been with Othello. (Act 1, scene 3, 381-382) He holds me well; my purpose works on him. This shows how conniving Iago is. He will use the fact that Othello trusts him to get his revenge. (Act 1, scene 3, 383-385) Cassius is a decent man. Show me now;To take his place, and to swell my willIn double rascality. As? As? We see. Here "double knavery" means pulling off a stunt and achieving two desired outcomes: gaining Cassius' position (which he felt he deserved) and being respectful for the sake of his ego. Another advantage of getting Cassio's position is that he can be closer to Othello. When he achieves this, he will be able to gain even more trust from Othello and will begin to manipulate him into believing that Cassio and Desdemona are having an adulterous relationship: (Act 1, scene 3, 386-389) After some time, to abuse the earsChe he is too familiar with his wife. He has a person and a kind character to suspect - framed to make women fake. Iago knows that Othello is a man of integrity and therefore believes that others are until proven otherwise. Iago has no respect for integrity and consequently has no respect for Othello. This is evident in his reference to Othello as a “donkey” who can “be tenderly led by the nose"..
