Satan (Hebrew: שָּׂטָן satan, meaning "enemy" or "adversary";Arabic: شيطان shaitan, meaning; "astray", "distant", or sometimes "devil") is a figure appearing in the texts of the Abrahamic religions who brings evil and temptation, and is known as the deceiver who leads humanity astray. Some religious groups teach that he originated as an angel, or something of the like, who used to possess great piety and beauty, but fell because of hubris, seducing humanity into the ways of falsehood and sin, and has power in the fallen world. In the Hebrew Bible and the New Testament, Satan is primarily an accuser and adversary, a decidedly malevolent entity, also called the devil, who possesses demonic qualities.
Although Satan is generally viewed as having negative characteristics, some groups have very different beliefs. In Theistic Satanism, Satan is considered a deity who is either worshipped or revered. In LaVeyan Satanism, "Satan" is a symbol of virtuous characteristics and liberty.
