statement.

Nietzsche, in a rejection of the Judeo-Christian morality, addresses this in two works Beyond Good and Evil and On the Genealogy of Morals where he essentially says that the natural functional non-good has been socially transformed into the religious concept of evil by the slave mentality of the weak and oppressed masses who resent their masters. Whether there is a universal, transcendent definition of evil, or whether evil is determined by one's social or cultural background, Artists always have used symbols such as angels and demons as the appearances Good and Evil in their own works. But a modern Artist's attitude is mostly focused on the fluctuation between these two poles in both personal and social context of an ethical system. These works have both old and modern approaches in themselves. The confrontation of the viewer with himself in front of the mirror which can lead in a mat or clear picture indicates  the relativity of these moral concepts and moreover, emphasises on making peace with our internal angels and demons, and on reinforcing the angels and controlling the demons.
