…often the wicked so devote themselves to the practice of sin that they succeed in doing more wickedness than they would have been able to learn from the bad example of reprobate sinners. For this reason the torment of greater punishment is inflicted on them, in that they, by their own initiative, sought out greater ways of sinning, for which they are to be punished. Consequently it is well said: “According to the multitude of his devices, so shall he suffer [a citation from Job 20:18]. For he would not find out new ways of sinning unless he sought them out, and he would not seek out such things unless he were anxious to do them deliberately. Therefore, in his punishment, this excess in devising wickedness is taken into account, and he receives proportionate punishment and retribution. And even though the suffering of the damned is infinite, nevertheless they receive greater punishments who, by their own desires, sought out many new ways of sinning.
–Gregory the Great (540-604), Book of Morals 15.18.22
