Othello suicides not because he killed Desdemona, but rather because he killed her on the mistaken understanding that she had desired and loved another man. The implication is that if she actually had an affair with Cassio, Othello would have considered the killing justified, and not taken his own life.

Indeed, the tragedy of the play could have been prevented by recognising Othello’s controlling behaviour towards Desdemona as violence arising out of societal attitudes as much as Othello’s personality.

There is no tragedy in his mistaken murder of Desdemona. There is no honour in killing her even if she was unfaithful. A modern view of family violence leaves Othello as nothing but a killer acting out the narrative of gendered violence of the 16th century Venetian society presented by Shakespeare. We are left without a tragedy and just a murder.

For a 21st century audience informed by the findings of the Royal Commission, the pathos of the play comes from how unnecessary and preventable – yet inevitable within the story – are the deaths. And how such deaths continue today.
