Moral evil arises from intentional actions or inactions by moral agents that are morally negative. There are three types of evil: metaphysical, physical, and moral. Moral evil is found only in intelligent beings and deprives them of some moral good. Sin is defined as any thought, word, or deed against God's eternal law. While temptation itself is not a sin, it can lead one to sin if they consent to improper desires. To resist temptation, one must pray, prepare their will through self-discipline, and turn away from occasions of sin.
