The theme of appearances -v- reality in Act 1, scenes 1 and 3, whereby Shakespeare immediately establishes Iago's evil intentions to gain revenge against the noble Moore, "Othello", also underscores the values of honesty, when Iago states: "I am what I am... Iago" hides under a facade of honesty for his own evil gains. The language clearly conveys his dishonest approacch to bring Othello down. The hatred he feels is based on the flimsy motive of the rumour about his wife. "It is though that betwixt the sheets he hath done my service". The characterization of this machiavellian villain sets up the downfall of the noble "Moore".
Paragraph 2. trust, get quotes from scene 4.
The theme of trust is explored by Shakespeare in the Iago/Othello relationship, showing the antithetical behaviour of the protagonist and antagonist. For example, Iagousing Cassio and Desdemona's friendship to poison Othello's mind. He is an opportunist who turns their innocent friendship to his advantage. Ironically, Iago falsley warns Othello of the "green-eyed monster" when he is the one that plants the seeds of jealousy in Othello's mind. Othello allows Iago to overcome him with emotion as he naively trusts him "And i know you're full of love and honesty, and you think carefully before you speak". (act 3, scene 3)
Furthermore, the theme of trust is evident in the way in which Othello, the noble protagonist, is undermined by circumstances engineered by Iago, in whom he misplaces trust. For example; "Look here, Iago, all my fond love thus do I blow to heaven. 'Tis gone. Arise, black vengence, from the hollow hell! Yield up, O love, thy crown and hearted throne To tyrannous hate! Swell, bosom, with thy fraught, For 'tis of aspics'
