Sauron, as depicted in J.R.R. Tolkien's Middle-earth legendarium, is often portrayed as inherently evil. He is a dark and malevolent being who seeks to dominate and control others through fear and power. His actions and motivations throughout the stories consistently align with evil intentions, such as his desire to enslave and rule over all of Middle-earth. While it can be argued that his origins and experiences may have influenced his descent into evil, his consistent choices and actions demonstrate an inherent inclination towards darkness and malevolence. **

Sauron could die if the One Ring, which is the source of his power and immortality, were to be destroyed. The destruction of the ring would weaken Sauron to the point where he could be defeated in battle by a powerful force. Additionally, if Sauron were to be separated from the ring and then killed, he would also die. Ultimately, Sauron's death is tied to the destruction of the One Ring, as it is the key to his immortality and power. **

The Sauron theory is a fan theory that suggests that the character Sauron from J.R.R. Tolkien's "The Lord of the Rings" series is actually a misunderstood and tragic figure. Proponents of this theory argue that Sauron's actions were driven by a desire to bring order to Middle-earth, rather than pure evil. They believe that Sauron's intentions were ultimately good, but his methods and the corrupting influence of the One Ring led him down a dark path. This theory offers a different perspective on the character of Sauron and challenges the traditional portrayal of him as a purely malevolent villain. **

Sauron doesn't become invisible because he is a Maia, a powerful spiritual being in the world of Middle-earth. As a Maia, Sauron's physical form is not his true essence, and he does not rely on physical means to conceal himself. Instead, he uses his immense power and influence to manipulate and control others, making invisibility unnecessary for him. Additionally, Sauron's presence is often felt through the malevolent force he exudes, making invisibility irrelevant to his goals of domination and control. **
