How does Antony show the crowd Brutus is not trustworthy?

Antony undermines Brutus's credibility by highlighting the contrast between Brutus's claims and his actions, particularly by questioning Brutus's motives for assassinating Caesar. He repeatedly refers to Brutus as "an honorable man" in a sarcastic tone, which sows doubt in the crowd's minds about Brutus's integrity. Additionally, Antony presents evidence of Caesar's generosity and his intentions for the people, which contradicts Brutus's justification for the murder. This rhetorical strategy effectively sways the crowd's opinion against Brutus and incites them to question his trustworthiness.
