It is subjective to determine whether Marcus Aurelius was "good" or not, as different people may have different criteria for what constitutes goodness. Marcus Aurelius is generally remembered as a wise and just ruler who is known for his philosophical treatise "Meditations," in which he reflects on the Stoic philosophy of living in accordance with reason and virtue. He is also remembered as a military leader who fought against barbarian invasions and tried to defend the Roman Empire. Marcus Aurelius is often considered one of the Five Good Emperors, a group of Roman emperors who are known for their relative peace and prosperity during their reigns. However, like all historical figures, Marcus Aurelius had his own flaws and mistakes, and it is important to consider the full complexity of his character and actions.
