Christian Science believes that evil arises from a misunderstanding of the goodness of nature, which is understood as being inherently perfect if viewed from the correct (spiritual) perspective. Misunderstanding God's reality leads to incorrect choices, which are termed evil. This has led to the rejection of any separate power being the source of evil, or of God as being the source of evil; instead, the appearance of evil is the result of a mistaken concept of good. Christian Scientists argue that even the most "evil" person does not pursue evil for its own sake, but from the mistaken viewpoint that he or she will achieve some kind of good thereby.
