To insult someone we call him bestial. For deliberate cruelty and nature, human might be the greater insult. – Isaac Asimov
Although the time of death is approaching me, I am not afraid of dying and going to Hell or (what would be considerably worse) going to the popularized version of Heaven. I expect death to be nothingness and, for removing me from all possible fears of death, I am thankful to atheism. – Isaac Asimov
