I read the piece. I like it. There are only a few things I noticed after one read that could be improved.
After reading the first 2 paragraphs I'm thinking you are going into a discussion about sin, morality, temptation and things of that nature. By the end you leave the reader with a statement about Us and Them and humans being two sided coins more or less. Since you developed the latter topic more than the former, I'd make that seem to be the overall topic of the piece by mentioning it in the intro or as early as possible. Until then, it will feel like two essays blended together without a clear transition.
The whole thing would be more powerful if more of your statements were changed to declarative statements. The tone i felt seemed informative, so you kind of lose the momentum created by the provocative intro. By the time you compare the reader to Hitler you've lost steam and will probably alienate/upset the dumber/less open minded people in your audience.
Sorry if you feel like i'm trying to rip you one. I don't want you to take it that way.
