Rick is a bad leader, poorly written by bad writers, played by a bad actor. Almost everything Rick does is a contradiction in itself. He scolds people for things he does all the time. He doesn't want to "lead" but he wants to make the decision to boot Carol instead of taking it to the Council. And if there was a choice to leave her, there were a million better places to disengage from her and give her an actual chance.
"I'll lead when it's towards what I want, irregardless of whatever else wants. Everyone else can lead as long as it's towards what I want, so I have time to dig turnips and mope instead of taking care of my kids"
