Well Said: Tolkien's concern

The Ring is less morally ambiguous than the average realistic novel, but that's primarily because Tolkien wasn't especially interested in the problem of knowing right from wrong. His concern was to explore the psychology of the moment when you know right from wrong but aren't sure whether you have the courage and fortitude to do the right thing.

Yep. And that is why The Lord of the Rings is endlessly fascinating.
