Hell is just the threat that keeps people going to church and under control. This was most effective in the Middle Ages but its impact has wained.
Heaven is another thing that just keeps people in church and was used to make the peasants work and not question their shitty lives. "Your life is so shit because the NEXT life is gonna be great..."
Yeah, okay
In summary, I don't believe in Heaven and Hell. Or anything else from ancient fairytales.
