Bah. It's Iago, by a long shot, in my opinion. Iago's evil works by making everyone he has contact with think he is trustworthy and dependable. Iago even tells Roderigo he is neither, but Roderigo trusts Iago anyway. Iago undermines the very notion of duty and of a system of society which relies on everyone else telling the truth. The real danger of Iago is not to Othello or Cassio or Roderigo; the real danger of Iago is to society.
