It would definitely be a stark contrast to the more family-orientated band of survivors in season 1. Imagine a gang not unlike the Save-Lot Bandits; a bunch of cutthroats not above resorting to savagery and self preservation. Their behaviour is justified in their own eyes, of course. Remember when Lee asked the bandit in episode 3 why they were holding everyone else at gunpoint? "'Cuz we have to, that's why!"
But imagine if the PC were allowed to exert a redeeming influence on the bandits, or at the very least, shaping them into something a whole lot less bloodthirsty than they were before. Some of the bandits would refuse to change their ways, while others...well, you get the idea. It would put the player into an incredibly suspenseful situation almost throughout the entire game, and this time, you wouldn't be given as many chances to catch your breath as you did in season 1.
