I think that anyone reading this concentration camp account must be struck by the intense surreality of what is being narrated. It is just so unbelievable and horrid and so far from our experiences in the 21st Century that we are just unable to comprehend the full extent of the horror that the author relates. What Wiesel is saying is that the way he was treated finally made him consider himself to be inhuman. The Germans treated the Jews as little more than cattle to be set to work and slaughtered on whim. Finally, this treatment impacted Wiesel and the way that he viewed himself. There are numerous instances in the novel to show how treating Jews like animals lowers their own standards of humanity as well, such as when they fight on the train for bits of bread that German spectators throw for them.
