Do Antony really believe Brutus is honorable?

In Shakespeare's "Julius Caesar," Antony repeatedly refers to Brutus as "an honorable man," but this is deeply ironic. While he ostensibly acknowledges Brutus's honor, Antony's true feelings reveal contempt for Brutus's betrayal of Caesar. Through manipulative rhetoric in his funeral speech, Antony ultimately undermines Brutus's credibility and incites the crowd against him, suggesting that he does not genuinely believe in Brutus's honor.
