Roderigo: A wealthy Venetian gentleman, Roderigo pays Iago to keep him informed of Desdemona's activities since he hopes to one day marry her. Trusting of Iago, he nonetheless questions Iago repetitively on his loyalty to him in Act I, and later on what has happened to gifts given to him to pass on to Desdemona in Act V.
Nonetheless he listens to Iago's calls not to give up when he learns of Desdemona's marriage, unaware he is being led on a fool's quest to simply finance Iago. Lured by Iago to fight Cassio twice (First in Act II, Scene III and later in Act V, Scene I), Roderigo is ultimately killed by Iago.
