人性中的无耻Shamelessness in human nature

狐狸说：人类总是说狐狸最阴险狡猾，这一点没有说错。因为狐狸能识破人性的无耻，人和人之间的内部争斗是世界上最残酷的杀戮。

The fox said: Humans always say that the fox is the most insidious, and this is not wrong. Because the fox can see the shamelessness of human nature, the internal struggle between people is the cruelest killing in the world.
