Othello Acts I and II

In the first Acts of this play, we are introduced to its main characters. Iago is evil, conniving and the antagonist of the play. He is basically "the sheep in wovles clothing." He pretends to like everyone while striking each of them in their backs. Othello so far is seen as a noble man who believes in justice. Desdemona is a very passive and submissive wife. She not only loves Othello but worships him as well. Roderigo and Cassio are two people who are secretly in love with Desdemona but cannot have her since she is already married to Othello.
Iago's main reason for not liking Othello is because he was passed over in postion of army and his position was given to Cassio. This is the main bone of contention in this play and it starts the ball rolling from the first scene. Due to this Iago decides to take revenge on Othello no what it takes and uses anybody (Roderigo, Cassio) to get to his goal.
