How bad was the Holocaust?

Pretty bad for six million gypsies, homosexuals, Jehovah's Witnesses, Jews, and others who were killed.

The Holocaust was probably the worst thing that ever happened to the world. Over six million Jews were killed and that is not including all the other races of people. People from Poland, Denmark, France, The United States and many other countries had people die from either fighting or just geeting caught by the Nazis and one guy choosing your future by the turn of a finger. Many people even buried their own grave. And there's much more. That is only a sample of how bad the Holocaust was.
