If you enjoy morally upstanding protagonists, you might want to stop reading this right now and go pick up, oh, I don't know, The Kite Runner.

However, if you're anything like me, you'll love a book that offers you a frontrow seat to a world of questionable decisions and ulterior motives. The books on this list don't merely touch upon the seven deadly sins — they are books defined by lust, gluttony, greed, sloth, wrath, envy and pride. The characters in them aren't necessarily good people, but they do provide for entertaining and insightful reading.
