I dunno. Shane's an asshole but I kinda feel bad for the guy. The character's an asshole in the comic books but he really honestly DID think that Rick was dead, or at the least that he panicked at the hospital. He didn't know if he could move Rick or not without killing him.
So again, Shane's a complete asshole, but earlier in the season they totally wrote Shane as they guy who felt like he was the leader, helping be a role model to a kid, working with a family and then all that shit fell through the floor the moment Rick came back.
Poor guy. Asshole. I can see both sides of it.
BTW...Lori's totally gonna be pregnant.
