Guilt is a cognitive or an emotional experience that occurs when a person realizes or believes - whether justified or not - that he or she has violated a moral standard, and is responsible for that violation.It is closely related to the concept of remorse.In psychology, as well as in ordinary language, guilt is an affective state in which one experiences conflict at having done something that one believes one should not have done (or conversely, having not done something one believes one should have done). It gives rise to a feeling which does not go away easily, driven by 'conscience'. Sigmund Freud described this as the result of a struggle between the ego and the superego parental imprinting. Freud, an atheist, rejected the role of God as punisher in times of illness or rewarder in time of wellness. While removing one source of guilt from patients, he described another. This was the unconscious force within the individual that may contribute to illness and also to the kind of so called accident that, until then had been attributed to God's will or simply bad luck.
