The Big Pig follows the perspective of Peter in a world that has been ravaged by “The Big Pig,” which represents greed. By giving into greed, by “drinking the green milk,” you hurt those around you and are left alone with only greed, as illustrated by Claudia. This post-apocalyptic landscape is only countered by one’s ability to care for their neighbors. Though, as Peter puts it, Bryce is weak and worthless, John still wants to help him, and thus does not end up giving into the Big Pig. Peter, however, abandons them to fulfill his own desires, and thus eventually gives up his life for greed.
