How does evil produce evil in The Hobbit?

Like orcs, history is created. Morgos was originally named mirko. Mirko is also a member of Villa, the twin brother of Manwei, the number one in Villa, and Ennu, the first born, is also the most powerful one. After the fall, he had a new name, Morgos, also known as Monty. Soren, the villain of the Lord of the Rings series, was originally his messenger. The evil creator creates evil and ugly. History's greed for treasure has reached an unattainable level. Tolkien described history's obsession with monopoly wealth as follows: "It's like a rich man with great wealth suddenly finding a treasure missing, even though it is completely useless to him." . History is very powerful, as can be seen from the example of scaring the spirit of Serando. But for the audience, the horror of Shi lies not in his dragon breath and invincible fighting capacity, but in his concentration and greed for his works. In fact, in real life, we don't need much effort to find human beings with this kind of concentration quality. They are our relatives, friends or rivals, or they may be ourselves. ?
