His prayers are evil who hopes to have someone to hate or to fear in order to conquer them. If, therefore, it was by waging 'just wars,' not impious or iniquitous ones that the Romans were able to acquire so great an empire, why shouldn't Foreign Iniquity also be worshiped by them as a goddess? For we see that She has contributed much to the extension of empire, she who fabricated unjust foes so that there would be enemies with whom the Romans could wage just wars and augment their empire. Why, moreover, shouldn't Iniquity also be a goddess -- at least one of foreign nations -- if Trembling Fear, Pale Terror, and Fever have merited being Roman gods?
