What does this tell you about how Tolkien regarded human nature?

Tolkien believed that humans are inherently flawed and prone to making mistakes, but that they also have the capacity for great good and heroism. He explored these themes in his works of fiction, such as "The Lord of the Rings," where the characters must overcome their own weaknesses and fears in order to achieve victory against evil. Tolkien's views on human nature were shaped by his Christian beliefs, which emphasized the importance of humility and repentance. He also believed that humans have a special connection to nature and that they are responsible for stewarding the Earth. Tolkien's works of fiction reflect his belief that humans have the potential to achieve great things, even in the face of adversity, if they are willing to work hard and strive for the common good.
