How does sallust's account demonstrate the destruction of the roman ideal and the failure of the roman republic?

Sallust's account highlights the moral decay and corruption that plagued Roman society, illustrating how greed, ambition, and factionalism undermined the republican ideals of virtue and civic responsibility. Through his portrayal of figures like Catiline and the political turmoil of the time, he emphasizes the erosion of traditional values and the rise of self-interest among the ruling class. This shift ultimately led to the collapse of the republic, as the institutions designed to uphold order and justice became tools for personal gain and power struggles. Sallust's narrative serves as both a reflection on the past and a cautionary tale about the fragility of republican governance.
