Throughout the well-written play of Othello, the readers can see many dynamic characters and the various emotions they experience. Othello particularly goes through a rollercoaster on emotions in this play, and it’s not all entirely his fault. The jealousy of Othello must first be analyzed as to how it begins. We are not sure of the validity of Iago’s claims, but Iago’s revenge on Othello is partially based on his believing that Othello slept with his wife. Iago is also consumed with hatred for Othello after Cassio is promoted over himself. While we can’t be sure of the validity of Iago’s basis for revenge, we know he is certainly motivated. Othello begins the play as a highly moral and outstanding individual. As a solider he is aware of public perception and cares how people see him, especially since he oversees other soldiers. Unfortunately for Othello, Iago, having been with Othello for a while, has seen him insecure and susceptible for overreaction. This leads Iago to plant false information in Othello’s ear and mind. Othello then susceptibly believes Iago’s lie about his wife, Desdemona, being unfaithful to him. The small seed planted by Iago sends Othello into a blind rage which he never comes back from until it is too late. The reason for Othello’s unnecessary fit of rage is because Iago was trusted by Othello, and had no reason to not be trusted up to this point. With the issue having been sexual infidelity, Othello can hardly believe, but does, that his wife has been unfaithful to him with his trusted friend Cassio. As Iago continues to point out examples of how Cassio and Desdemona must have been meeting up, Othello gets increasingly entrenched in his wrath and lust for revenge. Only after killing his wife does Othello return to a rational state of mind. We once again see the collected and moralistic thinking Othello return to the stage. In fact, he is so moralistic that he believes the only recompense for his actions is his own death. Since this is a tragedy, we expect a bit of death and tragedy, however, seeing the raw set of emotions Othello goes through is very depressing to read about.
