This is how hard line communist (or any totalitarian) government works. There must be no criticism, no sign of weakness, no compromise. The leader is all wise, all powerful and untouchable (unless he´s about to be replaced). They are not presenting themselves as men with flaws and conscience. They are the personification of unlimited power and behave accordingly. This is the case in Russia (you do not criticize Putin), in China with Xi, in North Korea with Kim.
