i don't really care for the moral accusations you throw at me, because the "severity" of the whole thing really can be questioned. You're looking at this as it is all black and white.
This whole topic can be related to the ethics of getting old tests and whatnot, and this issue has been argued to death in the past. Some say that its cheating, while others say that its not. The main thing i can conclude from my problem, was that I made a bad move by emailing the whole class. Yes cheating goes on, and if you're telling me you haven't ever cheated then i'll poop golden eggs for ya. Second of all, you make it sound like that the moral code in this class is so sound. I can tell you that this professor is lazy and has skipped already 3 days of classes, one of them being because he needed to go on a field trip for his kid's trip. If we're paying dollars to go to class, everyday he needs to know his priorities as well [not that i'm arguing he shouldn't cancel class or anything].
Life's not always that simple. What if everyone else in your class was helping each other out, and you were excluded and you couldn't prove a thing? i.e. extreme case say everyone is taking adderall as a study drug for a test, and you're not - perhaps you'll have a huge disadvantage.
My reason for sending the email out to the class, was based on that. Instead of having 4-5 kids having the answers for themselves (and the quiz idea can be questioned itself), why not just eliminate that by having the whole class. Yes, now ir ealize that it was a stupid mistake, and i won't be doing that again, because there are a bunch of tools who go tattle-tale.
peace.
