Well well well, listen to me!!
I've just read (in a site) some opinions about Dumbledore's death.
well well well, i start with a question. And if Dumbledore's death has been just a part of a gran plan?
We all know that Dumbledore's NEVER been wrong and maybe he wasn't wrong even this time! And now i will give u my reasons! If he's never been wrong, he culdnt have been wrong even about Snape!!!
In fact, if you read the pages with more attention you will realise that it could be really a plan organized by Dum and Snape!
When the Dead Eaters came into his office, he (Who knows why) stopped Harry with some kind of magic! And we all knows that if Harry hAd been able to protect his Headmaster he would have done it. So, maybe Dum DIDN'T want Harry's help. Maybe, as i said before, it was just a plan, his death was a plan and he didn't want Harry to save him.
And when Snape came into the office, when he showed that he was a Dead Eater...well, I don think Dumbledore was really surprised or scared about it. On the contrary, he said just "Snape..." and "Snape...please..."
PLEASE??? he should be angry, shouldn't he? everyone of us would be angry after realising that a friend of ours has betrayed us for all the time! No, he wasn't angry, ha said just "please..." and I could add "please kill me Snape" it's like he was asking Snape to kill him, like he wanted Snape to kill him, like he had to persuade Snape to do it, to kill him!
Here there are the things which make me think that it all had been planned before.
Yes, Dumbledore's words could just mean something like"please Snape don't do it, don't kill me..." but so, if he didn't want to die, why did he stop Harry?
I don't think Harry'd have been able to face all those Dead Eaters, but he could just run away and ask help, or save his life at least! But Dumbledore didn't make him move at all! yeah because he knew that Harry would have done everything to save him, to protect his favourite Professor, his friend...
And maybe Dumbledore didn't want to be saved.....maybe there was a plan, maybe Snape was really a good person, who acted to be a dead Eater, a Voldy's slave, just to give Dumbledore the informations he needed....I hope so
Now free your minds and guess, i'll be waiting!
