In Cyprus, Iago intensifies his manipulation, using Desdemona’s kindness toward Cassio to fuel Othello’s jealousy. He plants doubts in Othello’s mind, suggesting an affair between Desdemona and Cassio, and provides false "evidence," including Desdemona’s handkerchief. Othello becomes consumed by jealousy and begins to mistrust everyone around him. As events spiral, Desdemona remains unaware of Othello’s suspicions, while Emilia, Iago’s wife, unknowingly aids his schemes. In the final act, Othello confronts Desdemona in their bedchamber and, believing Iago’s lies, kills her. Emilia reveals the truth too late, and Othello, devastated by guilt, takes his own life. The play ends with Iago exposed but unrepentant, leaving a tragic aftermath of betrayal, manipulation, and lost lives.
