In fact, Sauron during the Second Age was more powerful than Morgoth at the end of the First Age. Here's a quote from Christopher Tolkien's Morgoth's Ring that offers an extended explanation: "Sauron was 'greater', effectively, in the Second Age than Morgoth at the end of the First.
Characters who can easily defeat Sauron are; his Creator Eru Ilúvatar, his old master Melkor, and the Valar. Others who could overcome him would be Ungoliant who physically dwarfed Morgoth, and some great Maiar of Valinor described as almost as great in power as the Valar themselves.
Even at a fraction of his full strength, Sauron is undoubtedly the strongest character in The Lord of the Rings. As a Maia, there's a good reason the people of Middle-earth fear his return, risking their lives to destroy the One Ring and prevent Sauron from reclaiming his former glory.
So, while Sauron was evil, Morgoth was clearly much worse.
Creating the Ring simultaneously strengthened and weakened Sauron. With the Ring, he could control the power of all the other Rings, and thus he was significantly more powerful after its creation than before; but by binding his power within the Ring, Sauron became dependent on it.

Another thing to mention is that Sauron has bested multiple wizards before like Saruman or Gandalf, meaning that he'd eventually beat Voldemort in the end, though the Avada Kedabra could most definitely kill him. Boomstick: If you think Voldemort stood a chance, you'd be Saurong. Wiz: The winner is Sauron.
God is the most powerful entity in Tolkien's Lord of the Rings universe. The Elvish name for him is actually Eru Ilúvatar, meaning “the one, father of all.” So the question becomes: Who is the second-most powerful being? Originally, it was Melkor, “he who arises in might,” the most powerful of the Ainur (or angels).
Sauron feared Elves the most (hence his machinations to corrupt and control them) but he hated Men the most, not least because of the Numenoreans, who foiled him on a few occasions.
Isildur took up the hilt-shard of Narsil and cut the One Ring from Sauron's hand, vanquishing Sauron.
Melkor is the most powerful of the Valar but he turns to darkness and is renamed Morgoth, the primary antagonist of Arda. All evil in the world of Middle-earth ultimately stems from him.
The One Ring Made Sauron Weaker - Kind Of
Because Sauron lost his Ring, his power severely diminished, and it took him thousands of years to rebuild his power. Even after Sauron declared himself again, his sole focus was on finding the Ring, not on solidifying his dominion.
Gandalf was weaker than Sauron (which is why he was afraid of travelling to Middle Earth in the first place) but he went anyway with some promptings from his superiors and managed to destroy Sauron by simply being himself.
In The Lord of the Rings, it is said that had Galadriel chosen to use her powers for evil instead of good, she would have been even more destructive and terrifying than Sauron himself. Galadriel was the greatest and most powerful of all Elves in Middle Earth in the Third Age.
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.
It begins after Sauron's master, the evil lord Morgoth, is defeated. Sauron may have gone into hiding, but he's still alive: the series will eventually show Sauron's creation of the titular rings of power—including the one ring to rule them all.
How tall is Sauron? Sauron is portrayed as being 9 feet 2 inches (2.79 m) tall in the Lord of the Rings films.
However, in the Return of the King, Gandalf explains that when the One Ring is vanquished, Sauron will be "maimed forever, becoming a mere spirit of Malice that gnaws itself in the shadows, but cannot again grow or take shape.
The Third Age is the time period in which The Hobbit and The Lord of the Rings are set. This age is marked by the rise of Sauron against the Númenórean kingdoms and his eventual defeat during the War of the Ring. The Fourth Age is the time period after the fall of Sauron, when Dwarves, Men, and Hobbits prosper.
He's a Maia, an immortal spirit, so he can't actually die. And Tolkien's wider writings include suggestions that Sauron survives as a spirit of malice.
After learning that Elendil, whom he especially hated, had survived and was ordering a realm on his borders, Sauron made war on Arnor and Gondor. He struck too soon, however, and had not restored most of his strength, whereas the Elven-king, Gil-galad, had increased his power in his absence.
He seems to be extremely loyal to Morgoth (at least as far as I've read), and I recalled a passage in Lord of the Rings where Gandalf said: Other evils there are that may come; for Sauron is himself but a servant or emissary.
Sauron feared her
The author said that she was the “last remaining of the Great among the High Elves” in the Third Age, and consequently was the one person Sauron must have feared most among all his enemies in the War of the Ring.
He will fight in the Last Battle against the Valar and their allies, but will ultimately be slain by Túrin Turambar, the Man he cursed. By finally defeating Morgoth, Túrin will avenge not only himself, but all members of the race of Men.
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 ...
Most of the time that Gandalf knows Saurman he is known as Saruman the White. He was originally the chief of the wizards as well as the White Council that was formed to fight against Sauron. He was more powerful than Gandalf at these stages, but his study of dark magic turned him to support Sauron.
