Merle is given a chance for redemption in The Walking Dead Season 3 Episode 15 titled This Sorrowful Life. Michonne makes a valid point in her address to Merle when she suggests that if he was truly evil he wouldn’t feel remorse. Merle seems to take this to heart as he leads his own parade to make his last stand against the Governor. The zombie post apocalypse is a bleak place but perhaps some goodness remains?
