Hey, the Romans were great for their time, but you can't judge the past by modern standards. They outlawed human sacrifice by the Carthaginians, Phoenicians and Celts; they established rule of law above arbitrary dictates, so that provincials could appeal to Rome; they expanded their franchise, to ultimately weld disparate peoples into a whole, that thought themselves Roman. There is a lot to admire.
But no Empire is built without blood, and Rome spilled a lot. The slaves crucified next to the Appian way or when Jerusalem was taken; the sacks of Corinth, Numantia, Carthage; and no Empire is free of egregious abuses, such as meted out to Protagoras' daughters. It is what it is. On the broader scale though, the Romans tend to be the 'good guys' if such a thing exists in history, as they built a large stable and peaceful empire, that mostly replaced internecine warfare, arbitrary rule and acts just as egregious as those committed by Rome.
