The pleasure of those who injure you lies in your pain. Therefore they will suffer if you take away their pleasure by not feeling pain
TertullianIf we refuse our homage to statues and frigid images, the very counterpart of their dead originals, with which hawks, and mice, and spiders are so well acquainted, does it not merit praise instead of penalty [Christians were punished for not worshiping Roman gods] that we have rejected what we have come to see is error? We cannot surely be made out to injure those whom we are certain are nonentities. What does not exist is in its nonexistence secure from suffering.
Tertullian
