For an alternative to Tolkien's simple morality, consider “The Last Ringbearer” by one Yisroel Markov. It is effectively telling the LOTR story a Mordor point of view. Quoting from an article [1] about it:
"In Yeskov’s retelling, the wizard Gandalf is a war-monger intent on crushing the scientific and technological initiative of Mordor ... He’s in cahoots with the elves, who aim to become “masters of the world,” and turn Middle-earth into a “bad copy” of their magical homeland across the sea.
...the remnants of Mordor’s civilization fight a rear-guard guerrilla campaign to sustain the “green shoots of reason and progress,” in opposition to the “static” and “tidy” pseudo-paradise of Middle-earth under the elven regime."
