Othello realistic or no?

I think the themes used in Othello make it a very realistic play. The theme of jealousy and revenge are common human emotions that many of us experience. For example Iago in the end of Act 1 speaks of his plan to frame Cassio of having an affair with Othello's new wife Desdemona. Such an evil act is something that I consider very possible by people today. The thought of revenge crosses everyone's mind. Although Iago is very much evil in his doings it is not anything above what a person very much bent on revenge would do. He also mentions in Act 2 "a wife for a wife" he is furious of the rumors circulating about Othello and his wife and wishes to destroy Othello's trust in Desdemonda for revenge. Also there are no dramatic departures in this play. When someone needs to leave to appear as though they are going somewhere else it is perfectly normal when they depart.
