What Adolf Hitler and his NAZI's did was evil, sinful, barbaric, and sick. Adolf appears to have done it somewhat covertly concealing it from most of the German people. The North Koreans are more blatant about their sick and evil practices. They don't care what the rest of the world knows and why should they with China to back them up?
Man's evil and sin knows no boundaries when he is free from God's authority. This is what it is like to live in a society where Satan has all the controls.
May the Lord look after His own even in this hell on earth.
