Why the Nazi state or Germany got the reputation as the most dreaded criminal state?

The Nazi state gained a reputation as the most dreaded criminal state due to its systematic implementation of genocide, most notably the Holocaust, where six million Jews and millions of others were murdered. Under Adolf Hitler's regime, the government promoted extreme nationalism, militarism, and racial purity, leading to widespread human rights abuses, aggressive expansionism, and the instigation of World War II. The regime's brutal repression of dissent, forced labor, and concentration camps further solidified its image as a totalitarian state characterized by inhumanity and atrocity. This legacy of violence and oppression continues to resonate strongly in global memory and historical discourse.
