I'm not afraid I could be wrong, but I am afraid of what could be if indeed I am wrong. Hell just plain sounds mean, and heaven just has way too many contradictions and other problems to sound remotely likeable. It wouldn't be painful and scary, but kind of annoying and exhausting.
"For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring." - Carl Sagan
