Behold the Orc
Here is an interesting, if annoying article: Ecce Orcus! An Argument for Humanizing the Orc. Hidden behind a morass of politically-correct fog, there is there a good point. Orcs shouldn’t be nothing more than evil minions.
In Tolkien, Orcs were perversions of the elves and inherently evil – or at least thoroughly predisposed to violence and badness and therefore easily harnessed by evil. In most fantasy literature that orcs or goblins appear in, they tend to follow Tolkien’s pattern as they do in most other ways even as they fail to give them as much personality as Tolkien did.
