Iago's Systematic Destruction of Othello
Shakespeare shows how Iago's manipulation transforms Othello from an eloquent, noble leader into a jealous, violent man. Iago has an uncanny ability to identify people's deepest insecurities and exploit them mercilessly. He doesn't just lie to Othello - he systematically isolates him and becomes his moral compass.
The transformation is linguistically brutal. Othello begins the play with confidence in his speaking abilities, but his language deteriorates into fragmented, incoherent outbursts. When he screams "I'll tear her all to pieces!" and "Damn her, lewd minx!", he's adopted Iago's crude vocabulary and violent mindset.
Most tragically, Othello begins to internalise racist stereotypes about himself. When he cries "Arise, black vengeance," he associates his blackness with something negative, succumbing to the prejudiced views that others have projected onto him. This represents his complete psychological destruction.
Key Point: The play's peripeteia (turning point) occurs when Othello abandons love for "tyrannous hate" - this moment seals his tragic fate and shows manipulation's devastating power.
