Human effort to dig deeper into human sin, the oil covered skin and in monochrome it is just that, darkness, negated, flattening hair, hiding face beneath. If a match touched, they would burn away, the destination is this greed inherent. To permit death, to permit yourself to death to get away from a desert. Purgatory metaphor, grey closeup of fires at the end, whatever. It is made a waiting room because it is men too old in their youth, too young in their old age. The two that don't deserve it happily follow those that too into inferno, and it is exactly as they would think.
