Evil is ever-present in J. R. R. Tolkien's fictional realm of Middle-earth. Tolkien is ambiguous on the philosophical question of whether evil is the absence of good, the Boethian position, or whether it is a force seemingly as powerful as good, and forever opposed to it, the Manichaean view. The major evil characters have varied origins. The first is Melkor, the most powerful of the immortal and angelic Valar; he chooses discord over harmony, and becomes the first dark lord Morgoth. His lieutenant, Sauron, is an immortal Maia; he becomes Middle-earth's dark lord after Morgoth is banished from the world. Melkor has been compared to Satan in the Book of Genesis, and to John Milton's fallen angel in Paradise Lost. Others, such as Gollum, Denethor, and Saruman – respectively, a Hobbit, a Man, and a Wizard – are corrupted or deceived into evil, and die fiery deaths like those of evil beings in Norse sagas.
