In the play The Tragedy of Julius Caesar, the title character is only alive for about half the play. He isn't considered the hero, or even one of the two main characters, because he isn’t the character that the audience watches struggle with internal conflict. Brutus and Cassius are the most human of the characters, in that they have goals and misgivings that develop throughout the play.
At first, Brutus cannot decide whether to join the conspiracy. Once he does, he conflicts frequently with his friend Cassius, and they argue violently at one point. In Cassius we see emotional turmoil as he doubts Brutus’ loyalty and friendship for a while.
Although the name Julius Caesar appears in the title, the word “tragedy” refers more to the fate of Brutus and Cassius than to him. Their motives are considered to be purer and more admirable than Caesar’s. The true tragedy is that Brutus and Cassius could not attain their goal of removing Caesar and keeping Rome free of tyranny.
