At this point in the play, Othello realizes his tragic flaw. Love blinded him to Iago's lies and Desdemona's innocence. He declared that it was his love that was his downfall, he was not smart to trust those closest to him (his wife) but to believe that Iago, who was his friend, was the truthful man. As a tragedy, the tragic flaw of the main character must be exploded in order for the climax to take place and to be resolved. In this play, Iago takes advantage of Othello's tragic flaw, and in turn uses it to manipulate the people around him throughout his plot for revenge. Iago plays off of Othello's emotions, particularly his love and trust for his wife. Iago's planned paired off the emotions that Desdemona's had for her husband and Cassio, as well as the feelings Rodrigo had for Desdemona. By creating a love triangle, Iago was trying to settle his revenge on Othello passing him up on the promotion and sleeping with his wife. The importance of this scene was to expose Othello, and for him to realize what his tragic flaw was, and how it was the final blow to his downfall. After admitting his flaw and knowing who was truthful and who was lying in his life, Othello kills himself, as he cannot live with the weight of what he has done.
