Living in a zombie apocalypse must be hard for anyone, let alone the leader of a group. Yet still, when this fictional horror happens, time and time again we expect a man to rise up and take command. It's just human nature  some people are born to lead, and just need the reason for doing so. Rick Grimes is one of these men. As the for-all-intents-and-purposes protagonist of AMC's smash hit The Walking Dead, Rick has all sorts of problems. He began the series comatose, dealt with an unfaithful wife, a disrespecting son, various psychopaths and his rapidly-unraveling best friend, and that was just for the first two seasons. The third saw him engage in out-and-out war against another settlement while attempting to keep control of his own insanity. Simply put, the man has it tough, so it's only natural he's going to make a bad decision every now and again. After all, nobody's perfect, and when you're under this much strain, it's always possible that you're going to screw up. So in honour of Walking Dead's upcoming fourth series (which looks freaking awesome, by the way) I've decided to catalogue some of the Grimes Paterfamilias' worst mistakes. If he can avoid errors of this magnitude this up-coming season, the prison might just have a shot. Needless to say, there's ain effect.
