Jealousy In Othello's Death

On a night of great tragedy in the late 1600’s. General Othello was slain by himself; after he strangled his wife to death. Gratiano had said that Iago was guilty of manipulating many people including Othello which all lead up to the murders of Emilia (Iago's wife), Desdemona (Othello’s wife) and Othello’s suicide. Iago also had a part in the death of Roderigo, a person who had got into the mix by simply being in love. Before Othello’s death, he had spoken about how he does not want people to think that it was all in spite of jealousy. “Speak of me as I am. Nothing extenuate, nor set down aught in malice. Then must you speak of one that loved not wisely but too well-” (words reported by Lodovico) Othello did not want to be remembered as one
Bartholomew Wittler, interviewed Cassio three nights after the murders occurred. “If I can promise you anything, I promise you this all that was said about Desdemona and I is false. She died because a man made the foolish choice to choose the words of a villain over the pure and innocent Desdemona” says Cassio. All of Othello’s fortune including his job went to Cassio the night of Othello’s death.
Iago’s punishment has not yet been declared to the public, “Othello had the chance to kill him” says Lodovico “i wish he would have, but i blame both parties. Why does man have to run on such foolish fuels? Jealousy, lust, love and anger. Othello was an angry man, that let Jealousy destroy him. All I want is for justice to be served to the lives lost in the night's tragedy.”
The public has flouted many rumors. Some might say, Iago did it because he wanted Cassio’s job; other people say it was because of raving jealousy from the rumors of his wife Emilia and Othello having an affair. But no one will know until Iago tells the truth. But will he speak the truth? And if so will anyone believe him. What should the government and army officials do with a madman shall he be institutionalized, imprisoned, or
