Taking things back to the black and white days, we see Rick talk to Morgan about his conflict at Carters fate. This was, of course, after Carter had held a gun to Eugenes mullet but before Carters walker-bitten demise. As Rick puts it, he feels that Carter doesnt deserve to be alive and that he wanted to kill him, with the grizzled Grimes giving off an almost God complex through this exchange. Eerily, Rick then reveals that things didnt have to go down that way because he knows that Carter will end up dead no matter what.
