The Antihero in American Television

The antihero prevails in recent American drama television series. Characters such as mobster kingpin Tony Soprano (The Sopranos), meth cook and gangster-in-the-making Walter White (Breaking Bad) and serial killer Dexter Morgan (Dexter) are not morally good, so how do these television series make us engage in these morally bad main characters? And what does this tell us about our moral psychological make-up, and more specifically, about the moral psychology of fiction?
