The attitude of those who are justified is different from the unjustified towards those who fall. Ham was not a justified man. Those who have received forgiveness wish others to receive it. They know it is a matter of grace and that they did not deserve mercy, but having received something so precious, they want all men and women to receive it. But the unjustified are still comparing themselves with others, and therefore the failings of others are seen as to their advantage. Ham wanted justification for his own waywardness.
