What is the point of act 3 and scene 3 in Julius Caesar?

Act 3, Scene 3 of "Julius Caesar" serves to highlight the chaos and mob mentality that erupts in Rome following Caesar's assassination. In this scene, Cinna the Poet is attacked by a furious crowd simply because he shares the name "Cinna," which reflects the irrationality and violence that have taken hold of the citizens. This moment underscores the themes of manipulation, the power of rhetoric, and the fragility of social order, illustrating how quickly reason can give way to chaos in the wake of political upheaval.
