As a young teenager with Christian upbringing, ethical/moral guilt was one of the reason I rejected the belief in Christian God. The guilt was too consuming. I knew well my do-not laws of God, to which none I kept. Every time I stole something, or told a lie, or explore my manhood, my conscience bored witness to the moral wrongness of the acts. The only way I could fight against my moral guilt was to eliminate the Christian God from the picture.
As Fyodor Mikhailovich Dostoyevsky’s character Kririllov put it:
“If God exists, all is His will and from His will I cannot escape. If not, it’s all my will and I am bound to show self-will.”
