Often considered the "true hero" of Julius Caesar, Marcus Brutus is a complex and multilayered character devoted to the welfare of Rome. Although he is Caesar's close friend, Brutus becomes increasingly concerned with the concentration of power in his hands, particularly as he suspects Caesar of ambition and tyranny. However, Brutus's judgment of Caesar is not necessarily reliable, as he is shown to be a poor judge of character, making his assessment questionable.

As a tragic hero, Brutus possesses a significant flaw: a rigid sense of honor. This trait blinds him to the dualities in others and makes him susceptible to manipulation. Ironically, despite his noble intentions, Brutus is the first to propose that Caesar's death may be the only solution to Rome's potential woes. Convinced by Cassius that the Roman public desires action against Caesar, Brutus joins the conspiracy and ultimately participates in Caesar's assassination.

However, rather than leading Rome to a more ideal future, Caesar's death plunges the city into chaos. Brutus's inability to perceive the threat Mark Antony poses proves disastrous, culminating in his defeat. Defeated by Antony's forces, Brutus dies by suicide at Philippi, leaving behind a complex legacy. Despite his failures, Antony famously declares him the "noblest" Roman, honoring Brutus's intentions if not his actions.
