The Book of Mormon teaches that 'the devil will not support his children at the last day, but doth speedily drag them down to hell' (Alma 30:60). This is vividly demonstrated in the interaction between Satan and Cain. Cain is promised that if he would kill his brother, no one would know. What happened, of course, was the exact opposite! Everyone found out that Cain killed his brother. He quickly learned the lesson that 'these things are not hid from the Lord' (Moses 5:39). For his murder, he was cursed, left to roam the earth as a 'fugitive and a vagabond', and given a mark by which everyone would know that he was a murderer (Moses 5:18-40). Cain's embarrassment was not limited to the people of his day. All through the ages, his actions have been famous. Even today, among those who have no religion and have never read the Bible, Cain's murderous deed is well known. So is his pathetic reply to the Lord, 'Am I my brother's keeper?' And so we learn, again, that we should never believe the words that are spoken by a serpent's forked tongue.
