Evil
Evil, in the general sense, is defined by what it is not—the opposite or absence of good. It can be an extremely broad concept, although in everyday use it is often more narrowly used to talk approximately profound wickedness as well as against common good. It is generally seen as taking business possible forms, such as the clear of personal moral evil usually associated with the word, or impersonal natural evil as in the case of natural disasters or illnesses, and in religious thought, the pretend of the demonic or supernatural/eternal. While some religions, world views, and philosophies focus on "good versus evil", others deny evil's existence and usefulness in describing people.
Evil can denote profound strife and expediency, loss and neglect.
In some forms of thought, evil is also sometimes perceived as the dualistic antagonistic binary opposite to good, in which advantage should prevail and evil should be defeated. In cultures with Buddhist spiritual influence, both good and evil are perceived as component of an antagonistic duality that itself must be overcome through achieving Nirvana. The ethical questions regarding good and evil are subsumed into three major areas of study: meta-ethics concerning the style of good and evil, normative ethics concerning how we ought to behave, and applied ethics concerning specific moral issues. While the term is applied to events and conditions without agency, the forms of evil addressed in this article presume one or more evildoers.
