Why does Cassius want Brutus to join the conspiracy?

• A. Brutus is a ruthless commander
• B. Brutus owes him money
• C. Brutus is Caesar's ally
• D. Brutus is respected and honorable

Answer: (D)

The key idea here is that Cassius wants Brutus to join because Brutus’s reputation for honor gives the conspiracy moral weight and legitimacy. Brutus is seen as a principled guardian of Rome, not a power-hungry traitor. If Brutus aligns with the plot, people—both Romans and senators—are more likely to view it as a virtuous action aimed at restoring liberty, rather than as a personal grab for power. Cassius flatters Brutus and appeals to his sense of duty to Rome, hoping Brutus’s involvement will sway others to support the cause and shield the conspirators from full blame. That combination of influence and perceived integrity is why Brutus’s participation is so valuable.
