One could argue that Othello’s tragic flaw is jealousy. Othello trusts the malevolent Iago, who is dedicated to causing his downfall. Iago convinces Othello that Michael Cassio is having an affair with Desdemona, which sparks Othello’s jealousy. Othello’s jealousy is also fueled by his self-doubt and low self-esteem. He understands that he is an aging foreigner, who is not particularly refined or attractive. Despite being initially dismissive, Othello eventually demands to have proof of his wife’s infidelity. Iago then goes on to tell Othello that he overheard Cassio talking in his sleep about his relations with Desdemona. Something as circumstantial as the handkerchief that Othello gave Desdemona becomes significant when she no longer possesses it. Iago uses the absent handkerchief to further influence Othello into believing that his wife is unfaithful. Unfortunately, Othello cannot see past his wife’s apparent infidelity and ends up murdering her out of jealousy. Othello’s suffering results mostly from his poor judgment. He trusts the wrong people and mistrusts those who are most loyal to him (Desdemona and Cassio). In Act 3, he sets aside his sensible, military side and falls prey to Iago’s manipulation.It must be noted in Othello’s case, though, that while he might share Brutus’s tragic flaw (from Julius Caesar), Othello deserves more sympathy from the audience. In a sense, he is a victim of his time period. While Brutus exercised poor judgment throughout Julius Caesar, he was used to commanding respect because of his family and character and did not have to fight against prejudice. In contrast, Othello’s poor judgment largely results from his self-doubt regarding his true acceptance into European society. He has been conditioned to think that he is not good enough for Desdemona or the inner sanction of white society.While some argue that Othello’s tragic flaw is jealousy, he really does not suffer from that until Iago plants seeds of doubt in his heart regarding Desdemona. Normally, Shakespeare’s tragic characters establish a pattern connected to their tragic flaws, and there really is no pattern to justify jealousy as a flaw with which Othello has constantly struggled.
