Envious, my heart! O dark and dreadful word!
When these with passion their bright destruction bless,
Who, drunk with the pulse of their own blood, preferred
Deep pain to death and Hell to nothingness.
- Charles Baudelaire, from Les Fleurs du Mal (translation by Humbert Wolfe) 
But what if there were no difference? What if Hell turned out to be not a place of brimstone and suffering but an eternity of nothingness, an infinity blank and inconcievable? How would we tell God from his absence? How would we decide between the believer and the non-believer, since both would see themselves vindicated?
Where one man sees a conspiracy of rules and punishment, the other sees only a universal indifference.
Nietzsche writes :
"It is the profound suspicious fear of an incurable pessimism which compels whole millennia to cling with their teeth to a religious interpretation of existence: the fear born of that instinct which senses that one might get hold of the truth too soon, before mankind was sufficiently strong, sufficiently hard, sufficient of an artist...Piety, the 'life in God', would, viewed in this light, appear as the subtlest and ultimate product of the fear of truth, as the artist's worship of an intoxication before the most consistent of falsifications"
Like the gambler who believes in chance, and is so caught up in watching it play out that he never notices that the buttons he is wagering with have no value.
Is this all God is then? A painted veil, a terror that we inflict upon ourselves only because it keeps us from seeing that other unappealable horror - the vertigo of nothingness. A fear we take comfort in.
 The original reads:
Et mon coeur s'effraya d'envier maint pauvre homme
Courant avec ferveur a l'abime beant,
Et qui, soul de son sang, prefererait en somme
La douleur a la mort et l'enfer au neant!
 from Beyond Good and Evil, (No. 59)
