Levi feels that the worst crime that the Nazi's committed was the fact that they were separated into special squads and were forced to fight upon themselves in order to survive the camps. They were ordered to help organize people to be put to death, were forced to search for valuables from the remaining ashes in the Crematoria and this was all done without any of them knowing what what actually going on. If they were opposed do doing the tasks asked of them they were either replaced by other people that would do the job or they were killed. The Nazi's forced people into helping commit the same crimes that they were committing and some people even went crazy performing the tasks asked of them. Levi felt that the worst crime that he Nazi's committed in the concentration camps would have been forcing innocent people into committing the crimes they were doing.
