Like Denethor, Sauron spends time mulling and attempting to predict the future—and given that the reader knows how this affected Denethor, it’s suggested Sauron might be tricked by the threat of his own predictions in a similar way. Mordor’s armies survive in a barren, uninviting wilderness, which shows that their existence is based on destruction and following orders, and completely bare of beauty or the joys of nature—an almost unthinkable existence for hobbits from the Shire.
