Iago believes in Othello, allowing him to take advantage of the situation and exploit it to his benefit. Cassio is already flirty and adores Desdemona, therefore Iago is able to persuade Othello that Cassio and Desdemona’s spouse, Othello, is having an affair.
To add fuel to the fire, the handkerchief given to Desdemona by Cassio was planted there on purpose. Othello worries that his wife is having an affair and that it would be disgraceful for a man in his position. So to him, if he kills his wife, she can no longer cheat on him.
Othello kills his wife, Desdemona, as a result of a clever plot by Iago. When he is riled with jealousy, he plans to murder her while she is asleep. She awakes, attempts to explain her innocence, and tries to appeal to him. Othello, unable to control his anger, smothers Desdemona with a pillow.
The death of Desdemona is undoubtedly the most tragic event in Othello for the cruelty of her murder and for the ill-fated reasons behind it. Being completely innocent, she becomes a victim of Iago’s sophisticated plot.
He instills in Othello the idea that his wife Desdemona has an affair with Cassio. Then he leaves her handkerchief on Cassio’s doorstep so that Othello may find it. That is when everything turns the final straw, and Othello gives up hope of saving his wife’s life. “I will kill you and love you after,” he boasts. Then he begins to put his diabolical scheme into action.
In Act V, Othello enters his wife’s bedroom with the intention of murdering her while she is asleep. He kisses her as a final goodbye, but she senses it and wakes up. Then he asks her to prepare to die, pray, and confess her sins.
Desdemona is confused by Othello’s fury and begins to beseech for her life. However, she says nothing of value, as he is already convinced of her adultery. They are unwilling to listen, and they have no trouble coming up with reasons and counterarguments, Othello takes a pillow and smothers her.
On the other hand, Iago believes that Desdemona’s murder will prevent many men from being misled. He feels that her death will aid a large number of people in avoiding betrayal in the future. The unpleasant truth is that, even after she had died, Desdemona continued to love Othello.
Emilia does not want Othello to be held liable for her death and insists that no one was guilty regardless of how much she hated him before dying. Finally, Emilia informs Othello about Iago’s true plan. After this, he asks others to remember him as a loving but impulsive individual. Finally, he apologizes for killing Desdemona and acknowledges his error.
