“I do not know.” Cain is now a bold-faced liar and is even blind to the fact that God can see right through his lie. This kind of blindness, and lying and murder, are characteristics of the Devil and his children (see commentary on Gen. 4:8). No wonder Jesus said that the children of the Devil were not really even able to say anything good (Matt. 12:34).

“Am I my brother’s keeper?” Children of the Devil prey on others and feel absolutely no responsibility toward them. The hate and indifference of the Devil and his children toward other people is completely in contrast to the love that God and his children have for others. Children of the Devil are notoriously interested in themselves rather than others. This explains why there is no biblical record of the religious leaders, some of whom were children of the Devil, rejoicing when Jesus healed or delivered someone. They invariably found some reason to disparage what he had done, even when he made the blind to see or raised the dead. There is no love for mankind among the children of the Devil, and Cain was one of them.
