Tone of "....Gas Chamber"

In most works about such a seriously devasting time of history, one would expect a more dramatic, or even gruesome tone towards a situation such as the Hallocaust. While this would be the way to convey the seriousness of the situation in older, more classic literature. I would like to think that this very "matter-of-factly" tone that the author chooses to use brings a new level of gravity to the situation. With this tone, the author provides the reader with several different feelings towards the Hallocaust. One view would be that the reader learns that the horrific event was so devastating that the author, himself having shared the experience as the narrator of the story, must detache himself from the memories and emotions of that time to cope with the pain of his memories. Describing devastating events with a devastating tone has been done for ages throughout literature, which could have led to a sort of detachment from the importance of the situation. At this point in time most people know and understand the disgusting, vile things that took place due to fasicsm and racism during the Hallocaust, and talking about it in such a calming, sarcastically mellow tone adds to a new level of horror.
