Roderigo is a young man of Venice desperately in love with Desdemona, who has been rejected both by her and her father.
He is completely under Iago’s spell, who milks his wallet for all it’s worth in the promise of furthering his suit to the lady. At Iago’s urging he wakes Brabantio to announce Desdemona’s flight to him, travels to Cyprus disguised in the hopes of gaining her favor, and in the end is willing to murder Cassio in the thought that this will bring him closer to his goal. He is rather brainless, somewhat cowardly, and only dimly perceives to what an extent he is Iago’s puppet. Wounded during his attempt on Cassio’s life, he is murdered by Iago to stop his mouth.
