Did folk miss the bit where Ezekial explains hes acting in a role of King as it was the best way to help people unite behind him and follow his cause? He gave a fairly long speech about it. Also the show would utterly die if Rick was killed off, anyone else and it would continue, but I can't see it without him. Personally, I want a Michonne/Darryl/Carl triple death, causing "Mad Rick" to reappear and just terminate his way around the Saviours stronghold
