I toggled back and forth on the morbid ending here. Having the boys sell the zombiefied corpses of loved ones back to their families seemed so nasty and awful, but it also made me chuckle. I tried a couple other ending ideas but nothing had the same sarcastic heartless bite as that mercenary idea, so I just went for it and I'm glad I did. That irreverant approach is exactly what makes Skullkickers tick.
