Troubled Iago    Unquestionably the most perfidious character within the cast of Shakespeare’s Othello is the cunning Iago. He spends his life, it would seem, taking revenge on the general and destroying nearly everyone around himself. Helen Gardner in “Othello: A Tragedy of Beauty and Fortune†elaborates on Iago’s exact function and place in the play: . . . Iago ruins Othello by insinuating into his mind the question, ‘How do you know?’ The tragic experience with which this play is concerned is loss of faith, and Iago is the instrument to bring Othello to this crisis of his being. His task is made possible by his being an old and trusted companion, while husband and wife are virtually strangers, bound only by passion and faith; and by the fact that great joy bewilders, leaving the heart apt to doubt the reality of its joy. The strange and extraordinary, the heroic, what is beyond nature, can be made to seem the unnatural, what is against nature. This is one of Iago’s tricks.
