Here's an interesting notion: Telltale have put out a "stats" trailer for The Walking Dead: Episode Four, which details the choices folks made, making for a sort of post-mortem breakdown of people's morality within the game. While I won't explode any details here, it's interesting that The Walking Dead players are by and large good guys. If you've played the game already, I think you will want to take a look to compare with your own choices.
It should go without saying that there are SERIOUS SPOILERS down there. Episode Five should shamble into the crosshairs of our morality math in a few weeks.
