Genocide is a denial of the right of existence of entire human groups, as homicide is the denial of the right to live of individual human beings; such denial of the right of existence shocks the conscience of mankind, results in great losses to humanity in the form of cultural and other contributions represented by these human groups, and is contrary to moral law and the spirit and aims of the United Nations. Many instances of such crimes of genocide have occurred when racial, religious, political and other groups have been destroyed, entirely or in part.
