Identifying the characters

So far in the play, Othello has introduced numerous characters in Acts I and II that seem to introduce the how future conflict in the play will unfold. The protaganist of the story is definietly Othello and maybe the Duke becuase he has an important role and seems to be mostly on Othello's side during the play. The antagonist in the beginning of the play seem to be Iago (Othello's ensign), Roderigo, and Brabantio (the senator). While Roderigo and Brabantio are both against Othello, I would guess that Iago is going to be Othello's main enemy due to how he can be closest to Othello and Othello doesn't know yet that Iago is against him. One pair of foil character I could see are maybe the Duke and Brabantio the Senator. While Brabantio wants Othello punished and turns out to despise Othello, the Duke thinks much of Othello and wants nothing bad to happen to him. One minor character that affects the plot of the play would be Roderigo. He is a minor character that helps shed light on the actions of Iago. If it were just Iago talking to himself about how much he hated Othello, the reader truly get the feeling that he may plan to do something bad to Othello. But with the ability to speak to Roderigo, Iago seems even more evil and he also appears to be more likely to cause great trouble for Othello. Because of this, Roderigo embodies and emphasizs the feelings of Iago towards Othello. This is a role the minor characters have in the play.
