“I don't believe in evil, I believe only in horror. In nature there is no evil, only an abundance of horror: the plagues and the blights and the ants and the maggots.”

I. Asimov: A Memoir (1994)
Context: If I were not an atheist, I would believe in a God who would choose to save people on the basis of the totality of their lives and not the pattern of their words. I think he would prefer an honest and righteous atheist to a TV preacher whose every word is God, God, God, and whose every deed is foul, foul, foul.
I would also want a God who would not allow a Hell. Infinite torture can only be a punishment for infinite evil, and I don't believe that infinite evil can be said to exist even in the case of Hitler. Besides, if most human governments are civilized enough to try to eliminate torture and outlaw cruel and unusual punishments, can we expect anything less of an all-merciful God?
I feel that if there were an afterlife, punishment for evil would be reasonable and of a fixed term. And I feel that the longest and worst punishment should be reserved for those who slandered God by inventing Hell.

All Men are Mortal (1946)
Context: In horror, in terror, she accepted the metamorphosis — gnat, foam, ant, until death. And it's only the beginning, she thought. She stood motionless, as if it were possible to play tricks with time, possible to stop it from following its course. But her hands stiffened against her quivering lips.
When the bells began to sound the hour she let out the first scream.
