While all of the previously listed traits make Shane an interesting character to watch, the thought of living with him in that world would have me hiding from him every day. The notion that a zombie could shuffle up to you and sink its teeth into your flesh while you're sleeping is scary, but Shane viewing you as a weak link is a nightmare. Given the opportunity, he wouldn't hesitate at all to blow out our brains if we're holding back the entire group or putting someone he thinks is more important in danger. Give me a pistol and I'd rather walk into a room filled with zombies than go anywhere near Shane. A human being that scary is a reason we love him... but from a safe distance.
