I realized early on that they are just creating an environment they're comfortable in. Civilized society is a burden for these people and they're liberating themselves from it. Look at them, they're happy as shit. They're acting their natural selves without laws to respect. Ever watch videos of caged animals being released onto grass for the first time? Are these looted cities beginning to resemble those on another continent?
