What about the Christian doctrine of hell?

What is hell? Why do you believe in it? Are you sure that the Bible supports your beliefs? Do you really think you need the fear of impending fire and brimstone in the afterlife to keep you on the straight and narrow? Or have you once again been duped by religious fear, guilt, and manipulation? I would like to challenge you to reconsider the huge assumption surrounding this doctrine. Hell, Hades, Gehenna
