The blog writter starts on a false premise -- applying a post-modern view upon LOTRO. Tolkien is perhaps the 20th century's greatest *anti* post-modern author, he deliberately took a romantic perspective upon his characters and writing style. It is a throw back to the heroic myth, inspired by tales originating in oral tradition and classical archetypes. Ontop of this backdrop, Tolkien imposes a christian (particularly catholic) ethic -- almost dogmatically so.

In Tolkien's universe, evil is a corruption of good. Evil acts lessen your connection with god (the greatest good). Morgoth's crime is one of vanity and closely parallells that of Lucifer, demons exist because they conciously deny God's supremacy (in LOTRO case this would be Illuvatar).

The creatures of Moria are irredemably evil. They are the direct descendants and spawn of those that sought to usurp Illuvatar's will, and afterwhich the Valar. their opposition to the peoples of middle earth are not one of mutual conflict over shared living accomodation, they despise the citizens of middle earth since they are Ainu's creation and represent his will.

Criticising LOTRO for a lack of moral relativism is like criticising a Ford Mustang for not being a boat.
