I disagree, if anything, an apocalypse will bring out the WORST in just about everyone. One of the themes explored to a very large extent in this show's comics (which we seem to be following VERY closely with the show, last night included) is how "good" people like Rick struggle to not become animals in order to survive. If this show goes down even HALF the roads that are in the comic series, this will be a very, very dark, depressing, and violent show. You think wife beating is bad? Just wait my friend...
