The Holocaust

Millions of Jewish people were killed. Suffered harsh beatings, tortures. The fact that it wasn't even about their race but their religion and the way they looked. It makes you wonder why they weren't better than a social or political class such as the Nazi's. What did they do to deserve that? Out of millions of soldiers apart of the plan only few were known to have hearts. Is a human brainwashed that badly that they cannot hear the cries and screams of man? There were even children who were apart of this horrid event. Could they not put their selves into the shoes of those people? How can one man in power influence only a small amount of soldiers, compared to the millions killed, to do something so malicious?
