Answer:
They are angry and vow to kill those who committed the crime.
In Act III, Scene II of "Julius Caesar," the crowd feels enraged and want to avenge his death when Antony shows them Caesar's wounds. At first, Brutus convinces people that he has killed Caesar because Caesar was too ambitious. Thus, before Antony speaks, the crowd trusts Brutus' right to kill Caesar, and considers the latter a tyrant. However, Antony's display of Caesar's stabs outrages Romans, who want to assassinate his murders: "Revenge! Let’s go after them! Seek! Burn! Set fire! Kill! Slay! Leave no traitors alive!"
