To seriously believe in hell you'd need to have a mind so open that your brain is at risk of falling out.
Think about it:
When we feel pain, the nerve endings send a message to our brain. Our brain read this message, recognize it as a warning to take action and we feel pain. If you're dead, your nerve endings (and brain) are switched off. Therefore the inability to feel pain.
If you're in "hell" you would need a physical body. A body that is alive and able to feel pain. Therefore as soon as the nerve endings have burned away you'd feel nothing.
And anyway, what about masochists? They love pain. Hell would be their idea of heaven.
And what about hell... is there carbon and oxygen in hell? Is hell subject to gravity and other laws of physics?
