Question

how do brutus and cassius respond antony's speech?

Answer 1

Brutus and Cassius responded to Antony’s speech differently. Brutus did not find anything objectionable in his speech; he allowed Antony to take Caesar’s body and bury it with proper funeral rites. However, Cassius objected to Brutus for allowing Antony to do so.

He knew Antony was Caesar’s true friend and could speak the truth about Caesar’s assassination which could make Romans against them. He also knew Antony was a great speaker who could change people’s thinking and perspective through his rhetoric. He did not like Antony. Earlier while the conspiracy to assassinate Caesar had been hatched at Brutus’s place, he had proposed to kill Antony also. But Brutus had objected to it.

Answer 2

Brutus says that Antony should not think that they are pitiless. He has a great pitiful heart. But they shall receive him 'all kind love, good thoughts and reverences
Cassius says that Antony shall have a say in disposing of new honours.
