Good against evil

In religion, ethics, philosophy, and psychology "good and evil" is a very common dichotomy. In cultures with Manichaean and Abrahamic religious influence, evil is usually perceived as the dualistic antagonistic opposite of good, in which good should prevail and evil should be defeated. In cultures with Buddhist spiritual influence, both good and evil are perceived as part of an antagonistic duality that itself must be overcome through achieving Śūnyatā meaning emptiness in the sense of recognition of good and evil being two opposing principles but not a reality, emptying the duality of them, and achieving a oneness.

Evil, in a general context, is the absence or opposite of that which is described as being good. Often, evil is used to denote profound immorality. In certain religious contexts, evil has been described as a supernatural force. Definitions of evil vary, as does the analysis of its motives. However, elements that are commonly associated with evil involve unbalanced behavior involving expediency, selfishness, ignorance, or neglect.

How to achieve good is also discussed in the social sciences and in biology.

The philosophical question of whether morality is absolute, relative, or illusory leads to questions about the nature of evil, with views falling into one of four opposed camps: moral absolutism, amoralism, moral relativism, and moral universalism.
