Part 4/7:
The exploration of Tolkien's letters reveals that unique beings of equal stature to Sauron could hope to harness the Ring effectively. Gandalf, also a Maia, could potentially overpower Sauron were he to wield the Ring. The notable distinction lies in the Balrog's ability to utilize the Ring without the burden of a moral conflict, a stark contrast to Gandalf, who would grapple with the fear of corruption.
This aspect raises the provocative idea that Balrog, if claimed, might defy Sauron's authority since the creature's implicit nature as a servant of Morgoth could lead it to view Sauron as a secondary figure.
