Are you saying that Rick was responsible for taking care of Hershel's head???
And Rick should find a way to split himself into clones so that he can be in several places at once protecting Beth, Carl, Judith???
Your examples are examples of a GROUP dynamic, not just a single leader.
Rick was not duped by the Governor. He knew he was bad. He got the prison ready for the Governor's first attack last season and they kicked his butt. Beat them so badly that they turned tail and ran and then the Governor had a complete meltdown and killed his army. Rick then lead the group to Woodbury to find and finish off the Governor, but found Andrea and the rest of the Woodbury residents instead. He then turned things over to a council of people to make the decisions because he didn't want the constant pressure of the Ricktatorship anymore. He also wanted to focus on his family and regardless of any situation, they are always going to be his first priority and all of his decisions will be made with their best interests in mind.
Snake - you can't compare Rick to Daryl and Michonne. It is not apples to apples. Rick has two other people to consider when he makes a decision. Daryl and Michonne don't have any family left to worry about. They do now to an extent since they joined the group and view the group as their new "family". If Rick is doing such a bad job at being a leader,
then why is no one else stepping up ? Daryl?? Michonne?? Nope, they continue to do their own thing. Carol? She keeps asking Rick to take charge again and she is on the frigging council!!
