I had a minor issue with the whole cannibale thing as it was only 3 months into the ZA. The had food.. The had all that corn, a cow for milk and butter and even to eat if they absolutely had to. I would even argue they had enough land to grow more veggies, so why turn to eating people?
It did make for an interesting twist within the story, I just wouldnt agree with that if I were part of the writing staff unless they decided for some other reason the St. John's were already cannibles like the Texas Chainsaw Masacre who killed people for the meat in their chili.
They had food and rational people do not resort to eating each other unless there is absolutely no alternative.
