Immediately before the Torah teaches us the source of the nation of Canaan’s degeneracy (so degenerate that we are taught in Vayikra 18:25 that the land would no longer tolerate its inhabitants) we are told that all the children of Noach left the ark. All, including Cham, the father of Canaan.
Each of them was found worthy of being saved with Noach. From this we can infer that this is true for current times as well. Differences in the character of nations, even if certain national characteristics border on degeneration, do not prevent a person from fulfilling the human mission.
All were created in the image of God (which was taught just a few verses above, 9:6) and no man can say to another “You are less of a human being than I am; in fact, you cannot even be classified as a ‘man'”.
Beraishis 9:18
pages 234-235
