If life were fair, anyone who managed to survive the apocalypse would be given a fuzzy blanket, some tea, and a nice bed to hide under and weep.
Life is not fair, obviously, and there's no actual end to the end of the world. Instead, there's grief and pain and mud and death, there are minor miracles, and there's the love that gets you out of bed in the morning, despite everything. Life goes on.
