What is an example of oxymoron in Julius Caesar?

An example of an oxymoron in Shakespeare's "Julius Caesar" occurs in Act 1, Scene 1, when the character Marullus says, "But, Brutus says he was ambitious; And, Brutus is an honorable man." Here, the phrase "honorable man" is an oxymoron because it contrasts with the speaker's implication that Brutus’s claim about Caesar's ambition is questionable, suggesting irony and doubt about Brutus's integrity. This highlights the complexity of honor and morality in the play.
