What do we tell ourselves, when we see the zombies coming for us? That society has already collapsed, so there’s no sense in trying to go out and rebuild or save anyone. That the only sensible plan is to cut ourselves off, to build a ball, to hunker down, to dig in. They’re not real people anymore anyway, so let them tear each other apart. Save yourselves.
Tell me that doesn’t sound familiar. Tell me it doesn’t mean anything.
