I agree that the Lucifer thing has many interpretations. So, I don't find that particularly useful here, but it was an easily identifiable story.
In terms of good/evil, it appears that many of these interpretations are very ego-centric. That is to say that the bunnies, angels, and such are not really good/evil because they do not act in accordance with the human definitions of what those things are. With that in mind, how it is any more (or less) valid for a human being to judge the actions of a bunny, angel, or devil as not being a real (as defined by human interpretation) version of good/evil any more than the same judgement can be made when looking at Orcish behavior and culture?
