God is limited in his goodness. He is detached from his creation. Forms of Deism and Sadism. To know the good necessitates an infinite, absolute standard. Those that re-define the nature of evil.
Evil is really good.
Evil, i.e., suffering, brings about good, therefore, evil itself is good. There is no real difference between good and evil. The Bible warns against making evil good and good, evil. This results in a dualism which teaches that good and evil are equal. No redemption or victory over evil is possible, only an eternal struggle.
