Explanation:
Iago’s motivation in “Othello” is a subject of debate among scholars and critics, as Shakespeare does not give a clear or definitive answer in the text. However, some possible explanations for Iago’s actions include his envy of Cassio’s promotion, his racial and sexual prejudices against Othello and Desdemona, his desire for power and revenge against those who have wronged him, such as Othello and Roderigo, and his sadistic pleasure in manipulating and destroying other people’s lives. Iago is a complex and ambiguous character, who embodies the dark side of human nature and the destructive forces of jealousy, hatred, and deceit.
