The death of hell is indeed the death of life itself, for it ensures a world without justice, without consequence, and without restraint. Like the Phoenix, Hell will always arise from its own ashes, bringing new horrors far beyond what our vaunted knowledge can comprehend or conquer. To deny the reality of hell after death is to guarantee its incarnation in life. Hell will not be denied; its horrors will be visited liberally upon those who acknowledge it least.
From The Doctor is In, The Death of Hell.
If hell does not exist, men would be wise to invent it. If it does exist, we are fools to deny it.
Today, the accepted definition of Hell is the absence of God. I can only surmise that with God's absence is the absence everything that reflects His glory, all of nature and all that is human that mirrors truth, goodness and beauty.
Ted Chiang's Hell is the Absence of God won both Hugo and Nebula awards as Best Novelle in 2002. You can read it at the link.
