There are many different themes in No Country for Old Men, but perhaps the most important is the theme of evil. Evil exists throughout the narrative, and the characters seem powerless to do anything about it. Anton Chigurh is evil personified, and Bell's actions, words, and reflections constantly remind the reader that evil exists, and is a powerful force in the world. Death and killing are two other themes. Both Moss, Wells, and Bell are all war veterans, no strangers to killing, and the drug war they are caught up in does not seem foreign territory to either of them. In fact, Moss and Wells are convinced of their own ability to escape the killing. Yet death stops both of them. Another, more subtle theme is love, personified by Carla Jean Moss and Loretta Bell.
