Caesar and Cleopatra (1945)
Julius Caesar: Go, Ptolemy. Always take a throne when it is offered to you.
Apollodorus: When a stupid man is doing something he is ashamed of, he always declares it his duty.
Julius Caesar: And so to the end of history, murder shall breed murder, always in the name of right, and justice, and peace, until the gods create a race of men that can understand.
