I think that is what makes the show so great though, the divide it causes by the moral decisions Rick/the group face. My other half and I usually have a post-episode 30 minute conversation about what was right/wrong/suspicious etc. For example (trying not to spoil too much for people not far into it here); I really enjoyed season two because of Shane, despite his 'methods' I think he was a survivor and did whatever was needed to protect the camp which rubbed off, and improved, Rick as a leader. he had to adapt to become a more uncompromising leader if he wanted to effectively protect his group.
