Most belief systems center around the necessity to improve ourselves and avoid sin. In almost every major religion, there is a source of good and a source of evil. Good is usually associated with one or multiple gods, while evil is often embodied by a malicious, destructive character. In Christianity, Satan is the personification of evil. He was once an angel called Lucifer who lived in Heaven, but he fell from grace and was banished by God. He was sent to Hell, a realm of everlasting fire where he would live forever among demons and the tortured souls of other sinners.
Satan's role in the Bible is to tempt Jesus away from his righteous path, and subsequently to inspire sin in mankind. Morality, sin, and evil are themes that appear in many religions, and are often represented by a monstrous figure like Satan.
