After reading the two acts of Othello, I believe that Iago is the main one to look at. Iago is very sneaky and has impacted the characters greatly, or at least he is trying his best to. Iago tries his best to make Othello look like a bad guy. He makes sexual references about Desdemona to the male characters in this story to get them to stumble and say something wrong. The story always seems to come back to him. He is the one trying to get people in trouble, but he is one who should be locked up. He is just a lonely, jealous, creepy guy that has nothing better to do with his life, so he messes up the others lives. He starts all the drama of this play and tries to turn everyone against Othello. He plays games and tricks to make people believe him and do what he says. Yet, that is all he is he is just a smart but evil man living his life through others so he does not take the blame. In the beginning of the first Act it shows us how Iago wants his revenge for not getting the position that he thought he deserved. He then convinces Othello that his wife is cheating on him with Cassio to get Othello to trust him more. He also gets Cassio drunk so that he does not remember killing the man, and he tells Othello he does not need a drunken man like Cassio. So Iago goes through all that trouble, and makes everyone look like fools, just to be at the position he thinks he deserves.
