From what we know of the human brain how would it react to the stimuli of, say, 1000 years of burning alive? Would they get used to it? What does a a mind that is used to burning as an existence act like? Would they eventually be able to stop screaming in pain on their own. Could you speak to that person?
Can a person, like me, who asks these questions ever put weight in the doctrine of Hellfire? I certainly have the means to imagine it fairly well.
