He explained that, like "all tyrants", Sauron had started out with good intentions but was corrupted by power, and that he "went further than human tyrants in pride and the lust for domination", being in origin an immortal (angelic) spirit.
There's no question that Sauron was as close as possible to being completely evil in the Lord of the Rings trilogy, but his beginning illustrates why he isn't completely. Originally, Sauron started as the opposite of evil-- a being of light that gave in to temptation.
No, he would not have been good for Middle-Earth. Sauron actually tried being good, though it didn't stick - possibly because his motivations for doing good deeds were suspect.
While Sauron is indeed one of the evilest entities in Middle-earth history, he wasn't always so, as The Rings of Power's premise states that "nothing is evil in the beginning." In fact, there were moments in the Second Age, after the fall of Morgoth, and even during the War of the Ring (depicted in The Lord of the ...
Sauron's evil grew from his original servitude to Morgoth, the world's first Dark Lord, into his own obsession for "mastering" all things in Middle-earth through wicked means. After Morgoth's fall, Sauron was fully autonomous and committed, for two Ages, to gaining tyrannical control over Middle-earth.
Sauron's deepest fear was that Aragorn would use the Ring against him. With its powers of domination, Aragorn could comfortably take over the entirety of Sauron's dark army. Though this would eventually corrupt Aragorn, it would allow him to destroy Sauron and take his place.
"So I think in his pitch to Galadriel, it cannot mean that he loves her or that there's any kind of romantic relationship. There should be no ambiguity around the fact that Sauron is evil — he's terrible, and he's using Galadriel to enhance his power."
Morgoth, the first to reign terror upon Middle-earth, was more powerful than Sauron and commanded an army of dragons and Balrogs. While both Morgoth and Sauron were cunning, Morgoth's rule and terror lasted longer and his corruption spread further, making him more formidable in the Lord of the Rings universe.
Sauron seemed to genuinely feel a connection to her, and part of that came from sensing the darkness inside of Galadriel. In that regard, his offer was really a seduction to the dark side.
There could have also been a darker reason that Galadriel didn't want to confess the deception. The events of the Lord of the Rings proved that Galadriel wasn't above temptation, further reinforced by The Rings of Power.
When he couldn't accomplish that, he began to war against the other Valar and rule over Middle-earth with his fires and evil creations. With this turn to darkness, Melkor became known as Morgoth. While at war, Morgoth lured many beings to his cause.
Saving Galadriel at sea was likely a method of gaining her trust, since Sauron would need an Elf's friendship to enter their realm. Whether he targeted Galadriel specifically because he could exploit her bloody-minded rage and broken heart is unclear.
Morgoth is the more powerful of the two. Morgoth was the mightiest of the Valar, a group whose weakest member would outpace Sauron. However, there are some circumstances and eras in which Sauron would win the day. Morgoth was born far beyond Sauron but lost and surrendered much of his power.
While the book version of Sauron is Pure Evil, due to being a manipulative sadist, which was shown in The Silmarillion, his lack of personality and motives in both the Ralph Bakshi and Rankin-Bass movies renders him not even close to qualifying in those versions.
Additionally, while he was in his weakened state, Galadriel could hold him off through the power of will alone. However, if Sauron had his One Ring and faced off in a battle against Galadriel, it's unlikely that there would be much she could do.
In a one-on-one battle, Galadriel would likely lose to Sauron. Even though she's an Elf, both powerful and intelligent, Sauron is Maiar. Odds are, Sauron didn't fear a physical defeat — only a fellow Maia ring-bearer could physically oppose him and win, after all — but Galadriel is threatening in other ways.
Eventually, Morgoth was bound in chains by the Valar and thrown into the Void, leaving the permanent damage his evils had done, and his former lieutenant Sauron, to trouble the world. One day, according to a prophecy, Morgoth will rise again in great wrath, but he will be destroyed in the Dagor Dagorath.
Sauron wants Galadriel to become his queen because she's useful, says Vickers. As he's already shown, Sauron can accomplish his objectives much more quickly when he has a highly regarded Elf warrior to get him into places like Numenor and Eregion (where Celebrimbor lives). “He feels a connection to her.
Sauron's only interest was an order or to work upon the world in an orderly state, even in the beginning, Mairon really had no love interest. Despite his deceptive attributes, he was a trickster and a seducer, he had little care for attempting to love someone.
Thus, Galadriel's dark form in Jackson's The Lord of the Rings personified what would have occurred had the Lady of Lothlorien given in to temptation and taken the One Ring for herself. She would have succumbed to evil because the Ring was indomitable, even with her power.
Finally Sauron came out to fight Elendil and Gil-galad face to face. When Elendil fell, his sword Narsil broke beneath him. Isildur took up the hilt-shard of Narsil and cut the One Ring from Sauron's hand, vanquishing Sauron.
Smaug the Dragon had destroyed both the Kingdom under the Mountain and the town of Dale, and Gandalf feared that Sauron might use the desolation around Erebor to regain the northern passes in the mountains and the old lands of Angmar.
