Tragedy is everywhere. In books, movies, and sometimes even in real life. Tragedy is when something truly terrible happens to people and they are left only to feel sadness. Not everyone has a tragic event take place in their life. That is why reading a tragic novel, or seeing a tragic play or movie can be so interesting. The audience who have not felt the emotions that facing a tragedy would give them would basically get a preview of those emotions.
“Tragedy (from the Greek: τραγῳδία, tragōidia[a]) is a form of drama based on human suffering that invokes an accompanying catharsis or pleasure in audiences"( Tragedy, Wikipedia Foundation). Its's weird how people enjoy books and movies that include people suffering. It gives them a chance to experience a lesser version of the harsh emotions real life tragedy would give them, without having to actually go through a devastating event. I suppose that could be why they enjoy reading about tragedy.
Some might say that the goal of tragedy is catharsis, which provides relief to the audience from any strong or repressed emotions.
Revenge tragedy could also provide some relief to someone who is seeking revenge on someone.The revenge tragedy, or revenge play, is a dramatic genre in which the protagonist seeks revenge for an imagined or actual injury. Although they might not get their revenge on the person they want revenge on, they could witness someone else getting revenge. That might provide some satisfaction to those who are out seeking revenge.
Reading tragic novels and seeing tragic movies or plays allows us to experience different things without actually going through them in real life.
