Iago

   In his Act I scene 3 soliloquy, Iago establishes his determination to ruin Othello's lives. When it comes up that there are rumors that Othello slept with his Iago, he sees it as an excuse to sabotage the other characters: "That twixt my sheets he has done my office" (I.iii). While most husbands would be angry or in denial if they had heard their wife had been cheating, Iago accepts it without question and interprets it as an opportunity. The notion that Iago is willing to wreck his marriage and his wife's reputation solely to seek revenge against Othello is strong evidence of Iago's treachery. Throughout the soliloquy, Iago pretends to think over his scheme, "Let me see now...how? how? Let me see" (I.iii). While he seems to be pondering the possibilities of his plan, it is evident that these are ideas he has been mulling over for a very long time because of the lack of hesitation to drag others into his scheme.
