As an incarnation of evil and a catalyst of jealousy, vengeance and murder, Iago is the mainspring of "Othello". One of Shakespeare's most intriguing characters, Iago sets out to convince Othello of his wife's infidelity with Cassio. His motives are diverse - revenge, vanity, envy - but he succeeds in arousing strong suspicions in Othello's breast. Though noble and courageous, Othello finally allows himself to be duped by the coldly calculating Iago, and 'Chaos is come again'.
