1. Brutus' Reupuation: Brutus is held in high regard by the Roman people and enjoys a reputation for integrity, honor, and justice. His involvement would lend credibility and legitimacy to their cause, making it more difficult for Ceasar to dismiss or counteract the conspiracy.
2. Political influence: Brutus is a prominent political figure and a respected senator. His support would bring a significant portion of the Roman Senate and the plebeians to their side. His influence could help sway public opinion and increase the chances of their success.
3. Moral Authority: Brutus is known for his ethical principles and devotion to the republic. His participation would serve as a moral justification for their actions, presenting the conspiracy as a noble attempt to preserve Rome's republican values and prevent Caesar from becoming a tyrant.
4. Military Expertise: Brutus is a skilled military commander with experience in war and leadership. His military prowess would add strength to their cause and could be vital in case of any confrontation or armed resistance from Ceasar's forces.
5. Psychological Impact: Having Brutus join the conspiracy would create psychological pressure on Ceasar. Knowing that even a virtuous and loyal friend like Brutus has turned against him could shake Ceasar's confidence and make him more vulnerable to their actions.
By gaining Brutus' support, the conspirators hoped to strengthen their position, increase their chances of success, and ensure public acceptance and support for their conspiracy to assassinate Ceasar.
