From reading your blog post and your comments here, I got the impression that you cared more about your pay raise than about the students learning.
Now, I'll be the first to admit that I could have misinterpreted whats been said and that you were probably a victim of circumstance, but you blame the guy for demonstrating a grade-seeking attitude while you yourself demonstrate a they're all cheaters, who are not worth my time and I don't want them to rate me lower in my evaluation money-over-doing your job attitude - I think he deserves the same benefit of a doubt as you do.
Your comments here seem very whiney and bitter and you show no sign of sympathy to the students who didn't cheat.
FWIW, the guy didn't sound very grade-seeking to me.
