Which character is not part of the conspiracy to assassinate Caesar?

Calpurnia is the character who is not part of the conspiracy to assassinate Caesar. In William Shakespeare's play "Julius Caesar," she is Caesar's wife, and her role is primarily that of a concerned spouse. She foresees danger for Caesar through her dreams and tries to persuade him to stay home on the Ides of March, demonstrating her loyalty and affection for him. In contrast, Brutus, Cassius, and Casca actively participate in the conspiracy, each driven by various motivations, such as concern for the Republic or personal grievances against Caesar. This distinction highlights Calpurnia's role as an uninvolved character who serves to emphasize the tragic fate of Caesar rather than as a conspirator who seeks to end his life.
