After committing such heinous actions, he should be punished. Punished for what? Has Iago committed any crimes that would be punishable under penalty of law?.
There is no penalty for lying. Iago had broken the bond between Roderigo and Cassio by telling Roderigo that Desdemona loves Cassio. He had also told Cassio that he would help him be reappointed as Othello's lieutenant after the fight with Montano. Iago had also said that he loved Cassio and Othello. Iago had told many lies to may people, He had backstabbed them, which is not a crime, but very mean.
Iago contrived ways to get revenge against Othello and Cassio. He planned the fight between Roderigo and Cassio. He was indirectly the cause of the stabbing of Montano, but Roderigo was the one who actually attacked him. Iago also wanted the break the relationship between Othello and Desdemona, mostly in part of jealousy of that "black ram". Breaking up relationships is not a crime in any court of law.
Iago had also caused Cassio to become drunk, who later provoked Roderigo into a fight. He also was the one who made Brabantio confront Othello and wedged the relationship between Desdemona and her father. Iago had also left the handkerchief in Cassio's home for Othello to find. He had planted many seeds, but it was the others who watered them and allowed the seeds to grow.
There is a difference between committing heinous actions and committing criminal actions. As we have seen, all of Iago's actions have been evil in intent, but he had never carried them out. Evil is not equal to criminal, and Iago is not guilty of any crime.
