Shakespeare arguably used his free will to create political and emotional change. You could say tragedy has the power to create catharsis, a form of emotional release. The society Shakespeare was in was quite traditional and didn’t favour anything non conventional, and the representation of tragedy can be considered to create political change through catharsis, as the audience will be led to think about the events that have occurred. You could say tragedy can be didactic, meaning it can teach moral lessons. Maybe Shakespeare used his free will to use tragedy as a tool for political change? In Othello, Iago plays on and shatters the hierarchalvalues, especially in his defiling of Othello and Cassio, high up members in society, highlighting ‘Othello’ even more as a tragedy. I hope this helped in any way!!
