Murellus and Flavius, Roman tribunes who are friends of Brutus and Cassius, come upon a group of common people running about the street in their Sunday best when they should be working. The pair asks about the commoners' professions and what they're up to and finds out that they're on the way to celebrate and honor Julius Caesar. "These growing feathers plucked from Caesar's wing Will make him fly an ordinary pitch, Who else would soar above the view of men And keep us all in servile fearfulness."
Brutus paces back and forth in his garden. He asks his servant to bring him a light and mutters to himself that Caesar will have to die. He knows with certainty that Caesar will be crowned king; what he questions is whether or not Caesar will be corrupted by his power.
Act V, SC.
Decius and Ligarius, followed by Casca, come forward to kneel at Caesar’s feet. Casca stabs Caesar first, and the others quickly follow, ending with Brutus. Recognizing that Brutus, too, has joined with the conspirators, Caesar speaks his last words: “Et tu, Brute?/Then fall Caesar” (III.i.76). He then yields and dies. The conspirators proclaim the triumph of liberty, and many exit in a tumult, including Lepidus and Artemidorus. Trebonius enters to announce that Antony has fled.
The two men insult each other, and Brutus expresses the reasons for his disappointment in Cassius. Because he claims to be so honest himself that he cannot raise money by ignoble means, he was forced to ask Cassius for money, but Cassius ignored him. Cassius claims that he did not deny Brutus, but that the messenger misreported Brutus’s words. Cassius accuses Brutus of having ceased to love him. He hopes that Antony and Octavius will kill him soon, for, having lost his closest ally and friend, he no longer desires to live. He offers his dagger to Brutus to kill him, declaring, “Strike as thou didst at Caesar; for I know / When though didst hate him worst, thou loved’st him better / Than ever thou loved’st Cassius” (IV.ii.159–161).
When Octavius refuses to agree to Antony’s strategic instructions before the battle, his obstinate resolution to follow his own will and his clarity of command echo Caesar’s first appearance in the play. In Act I, scene ii, Antony comments, “When Caesar says ‘Do this,’ it is performed”; such authority is the mark of a powerful leader (I.ii.12). Octavius, Caesar’s chosen successor, now has this authority too—his word equals action. Antony, noticing this similarity between adopted son and father, begins calling Octavius “Caesar.” Just as Caesar transforms his name from that of a mere mortal into that of a divine figure, Antony converts “Caesar,” once one man’s name, into the generic title for the ruler of Rome. In at least one way, then, Caesar’s permanence is established.
Ambition and Conflict. cassius is a great man, and he is very ambitious. His ambition is what worries Brutus, and its leads to Brutus joining the conspiracy to murder Caesar. Cassius is also a very ambitious man, and because he is so jealous of Caesar's power he wishes to kill him to gain more power for himself
