Religious responses to the problem of evil are concerned with reconciling the existence of evil and suffering with an omnipotent, omnibenevolent, and omniscient God. An argument that attempts to resolve the problem of evil is known as a theodicy.
The problem of evil is acute in monotheistic religions such as Christianity, Islam, and Judaism whose religion is based on such a God. However, the question of "why does evil exist?" has also been studied in religions that are non-theistic or polytheistic, such as Buddhism, Hinduism, and Jainism. In most theological discussions, evil is defined in a broad manner as any and all pain and suffering, but religion also uses a narrow definition that says evil involves only horrific acts committed by an independent moral agent and does not include all wrongs or harm, including that from nature.
