Looking at Act 3 scene 3 in detail trace Othellos journey from trusting Desdemona completely to expressing hatred and loathing for her in this scene. Examine in detail exactly how Iago manipulates Othello into this changing attitude.

question his own knowledge of his relationship with Des. After Iagos string of short questions “Honest my lord?" and along with his deliberately vague responses “My Lord, for aught I know", we can clearly see the tension and anxiety building up in Othello when he says, “Think, my lord!" this shows the dramatic importance of how Iago’s character has the ability to manipulate other characters in particular, Othello. At one point he advises Othello against exactly what he wants him to do which is to overreact and become obsessed with suspicion “I am to pray you not to strain my speech/ To grosser issues, nor to larger reach/Than to suspicion"(line 217). Othello claims he is not affected by Iagos doubts however begins to wonder how people can betray their true natures. “I do not think but Desdemona’s honest. “I’ll love no friend, sith love breed such offence" (line 371) and here Iago is seemingly regretful of telling his lord of his suspicions “I do repent me that I put it to you" (line 390). Iago seems honest and devoted to Othello, giving him little reason to doubt him.During the scene Othello goes through stages of jealousy, insinuated by Iago, who is the first to mention the word. “O beware my lord of jealousy" Here Iago is pointing out how destructive jealousy can be and reminding him of jealousy altogether and playing on that exact emotion. After Iago plants these first seeds of doubt however Othello dismisses the idea “Away at once with love or jealousy". Othello lacks in self confidence about his race and acceptance in another country. He ponders about Desdemona’s choice of men, why has she chosen Othello over any man. “To say my wife is fair, feeds well, loves company". In this scene Iago also highlights Desdemona has attractive qualities, other men will want her but at this point Othello trusts Desdemona and claims  “For she had eyes and chose me". Whilst Iago persists to put queries in Othello’s mind, you can tell from Othellos speech he is asking himself the same questions. Cassio has interest in Desdemona because she can help him to regain his position as Othellos lieutenant “Good Cassio, I will do all my abilities in thy behalf". However Iago ingeniously sees him as the ideal person to use in his plan to enrage Othello. Iago knows Othello would see Cassio as a threat as he is a fine, young handsome man.Iago continues his manipulation, here we are reminded of an assertion that Brabantio makes in the first act. “look to her moor, if thou has eyes to see: she has deceived her father and may thee". Here Iago is warning Othello, since he has been deceived by his daughter’s lies and he is intimating that she may well do the same to him enforcing Iagos aim to convince Othello his wife is not trustworthy and will be unfaithful. “she did deceive her father, marrying you"He then begins to be convinced that Desdemona has been disloyal, his wife that he once trusted her with his life “my life upon her faith" earlier on in the play has now been accused of an affair with Michael Cassio. Othellos emotions seem to rollercoaster, he trusts Desdemona but also Iago and seeing Cassio sneak off to avoid being seen with Des emphasises further they are hiding something when infact he just wants his job back. Othello trusts Desdemona but also has enough trust in Iago to be influenced by him. The quote “honest Iago" and “This fellows of exceeding honesty" is further highlighting the complete trust Othello has in Iago and again looks like the good friend and certain Iago is loyal to him, and because of this trust there is greater chance Othello may become brain washed by Iago. As well as showing this trust it also demonstrates Iagos devious and hypocritical but persuasive character. Iago says “In Venice they do let God see the prank/ They dare not show their husbands" implying that Venetian wives cheat but the truth is never known. He advises Othello to “look to your wife observe her well with Cassio". Othello thinks Iago is playing the good friend and makes out he knows more than he is telling Othello but just advises him to watch his wife carefully so he can see for himself. Othello is evidently taking notice at this point “My lord, I see you’re moved". The character of Iago, plays on Othello’s good nature and trust for Iago to convince him that someone else he claims to trust indefinitely has betrayed him. This shows his Machiavellian and devious nature and that he is malevolent, line 213 says “I humbly do beseech you of your pardon/For too much loving you" claiming the only reason he is doing this is because he loves Othello and means much to himIago has succeeded in his quest and Othello eager to know more sets Iagos wife out to spy.  “Let me know more; Set on thy wife to observe" Iago though says to give it time “scan this thing no farther. Leave it to time" he is telling Othello to not think badly of Des and that he could be wrong about her and Cassio but that time will tell. However Othello is too far set on believing she has done wrong and expresses hatred for her. In his soliloquy he reveals “I am abused, and my relief must be to loathe her”, Iago is able to see Othello’s trusting nature and gullibility and close friendship with him in order for him to believe all he says and turn a loving husband into the green eyed monster. Othello as a tragic hero, according to the typical mould, must have a fatal flaw that brings about his downfall. In line 198 Iago highlights his flaw this being his “free and noble nature" He exploits Othello’s insecurities and plays on his feelings of alienation from the society and background of Desdemona and Venetian women. The “green eyed monster” becomes a symbol representing Othello’s dark feelings, a thought in his mind and beginning to make him think differently.
