Final answer:
Cicero aims to stop Catiline by exposing his conspiracies, urging his followers, particularly Catiline's private bodyguard, to leave Rome and by rallying against political adversities to maintain the Roman Republic's stability.
Step-by-step explanation:
Cicero, in his various speeches and writings, proposes to combat the threats of Catiline by exposing his conspiracies and by rallying the Senate and Roman citizens against him. In his Second Speech Against Catiline, Cicero expresses his wishes for Catiline's forces to leave Rome, warning of the danger they pose should they remain. He highlights the necessity of removing Catiline's private bodyguard from the city, fearing they could continue Catiline's violent and seditious aims even after his death. Cicero emphasizes that such action is critical to the safety and stability of the Roman Republic. Additionally, he details attempts to defend the state against other political adversaries like Clodius and Metellus, accusing them of inciting violence and attempting to strong-arm their political agendas, which Cicero seeks to resist through legal and senatorial means.
