Final answer:
Mark Antony said the quote in Shakespeare's play Julius Caesar.
Step-by-step explanation:
The quote 'He was my friend, faithful and just to me. But Brutus says he was ambitious; And Brutus is an honorable man' was said by Mark Antony.
It is a line from Shakespeare's play Julius Caesar, specifically from Antony's speech in Act 3, Scene 2. In this speech, Antony uses irony to praise Caesar while subtly criticizing Brutus and the other conspirators.
