Dumbledore's Sacrifice - Part I

After having vacillated a great degree over whether Snape is bad or good and whether Dumbledore is finished or whether he will "rise again", I've decided regardless that Dumbledore has willingly undergone a sacrificial death of sorts. From the very beginning of the series there has been an insistence that death is not the worst thing that can happen to someone. Furthermore there is a precedent in myth (Norse, Arthurian, Biblical-New Testament) and literature (Tolkien, Lewis, etc.) that death is shown to be a transformation that the good do not fear but the evil do and subsequently misunderstand. In that sense, Voldemort (lit. "flight from death") is merely the latest on this infamous list. The following, I believe, at the very least clarify the difference between the way Dumbledore and Voldemort view life and death. It will be interesting to see if these clues play into a resurrection scenario: - Snape's first lesson in "Sorceror's Stone" finds him speaking of his ability to "stop a death" and he mentions the "draft of living death". Harry produces this potion in Slughorn's first class. Could this repetition be a clue to a "trick" on Dumbledore's part? - Non-verbal spells are emphasized over and over again in HBP and Snape appears to be a master of them. Could Snape have said "Avada Kedavra" and meant something else?? - If Dumbledore isn't "finished" then part of his sacrifice is an admission of defeat of which he is not afraid. Voldemort is inflamed by jealous anger by anyone who gets the better of him, particularly Dumbledore and Harry, but also his father and Amelia Bones among others. What I mean is that even if Dumbledore comes back, his action of losing face is unthinkable for the Dark Lord. - Dumbledore's comment to Draco: "No one can kill you if you are already dead." Hmmm...right before he is (supposedly) killed. -
