1)Wel, in comparison to the Carthaginians
The Romans were a holiday!; the represseive ways of carthage treatings its
subjegated cities (Unlike Rome, which could always be counted on offering those areas that had proven loyal to its rule to be a part of the republic, and empire as equals, the Carthaginians made no pretensis of equality; they were the best all those under thier control slaves, and would eventually culminate is soem very bloody rebellions in the Lybian coastline)
2)How do we know the "stories" of sacrifice are true? because archeologust have uncovered the burial pits where the remains fo the children were placed after thier killing, that how
3)The 3rd riech perverted the image of Rome for its own uses; the fact that America itself enshrines all things Roman in its own government shoudl be proof enough that Romes culture has influenced the world for both good and bad, and that it woudl be Rome taking out barbarian userpers in the eastern empier, not outsiders conqoring rome in the 40's.
4)it shoudl also be added that unlike most slave cultures the Romans had a practice of
manumission that is, unliek many slave keeping cultures, slaves coudl be expected to be freed after a time; either by death of a master, buying themselves out fo freedom (slaves were allowed to have side jobs on thie rown accord, as long as it didnt interfere with thier duties), or for exemplery service for thie rmasters; a surprinsglly civlizaed practice for the people you coin as "leading the league" in terms of cruelty- were the Romans crule? Yes,. they delt out harsh punishments; but they did so
as punishment, and not out of sheer perverse cruelty.
