THEMES
The incompatibility of military heroism and love; the danger of isolation- Othello is the perfect soldier, but his directness means he is unable to understand the subtleties of political life and affairs of the heart. Jealousy
Jealousy 1: The play opens with a discussion of jealousy. Iago is upset because Othello selected Michael Cassio as his lieutenant. He is jealous of Cassio's position both in the military and with Othello's service. This initial jealousy is the catalyst for the play's sequential plot of mixed jealousy and destruction.
Jealousy 2: Brabantio is partially jealous of the Moor for stealing his daughter's love. He no longer may be the most important man in Desdemona's life.
Jealousy 3: The lovesick Roderigo has trouble with his hidden feelings for Desdemona and is jealous watching the two in love..
Jealousy 4: Iago openly divulges his plan of destruction, which incorporates jealousy as the key factor. He intends to create a strong sense of jealousy in Othello by setting up the mirage of an affair between Desdemona and Cassio.
Jealousy 5: Iago plants seeds of jealousy in Othello and then speaks of the 'green-eyed monster' as a force to be feared. Jealousy is personified as a monster.
Jealousy 6: As the play concludes, all causes of jealousy are proved false. Desdemona was never unfaithful, but Othello realizes the truth too late. Jealousy is the source of pain and death for these tragic characters; the green-eyed monster has succeeded in killing them.
Revenge
Revenge 1: Iago's plot against Othello is partially motivated by revenge. He feels wronged because he was not made lieutenant. He is bitter and upset and wants to hurt Othello and destroy his world.
Revenge 2: Brabantio craves revenge for the loss of his daughter. He takes revenge by bringing Othello before the Duke to request his imprisonment.
Revenge 3: Iago develops his elaborate plot of revenge. He will implant a false sense of jealousy in Othello,
