I think that he made a concious decision to dye and yet I am wondering myself if that truely was Dumbledore. There is evidence pointing to the fact that he is and the fact that he isn't.

Thinking of it now however he seems like Dumbledore. When he was talking to Malfoy, that was his style to divert him and try to save him. Yet the pleading and everything really made me wonder, the overall coolness and wisdom that Dumbledore has been gifted with. Why would he plea? Maybe because he had thought Snape was on his side all along? If this was a plot of deception and sacracfice then I just dont understand it! If snape wanted to prove that he was loyal to Riddle and yet keep his composure he could have created a diversion or a non verbal spell to save albus.

Or was it truly an imposter? What about his hand, we do not know entirely why he substained that injury. It could have been a ploy to cover up a different appearance. Also why was he constently dissapearing? To just look for the items? All the evidence was in the pensive! There are somethings not adding up here.

Than you have the event in that Dumbledore brought Harry on that mission, did he know he would die? Was this Harry's final lesson so that once he would die harry could know what his tasks were to be?

Why did he stop Harry? Surely harry could have taken Malfoy! Why did dumbledore want to die? I know it wasnt because he loved harry so much, knowing that he did love harry.. he loved the school even more. There were many children who needed Dumbledore. And Dumbledore has inadvertantly allowed harry attack voldemort before, he knows that Harry will continue too untill he dies.
