He fears it and he so believed , everyone else would and hence the man , used the poison to kill one who tried to fetch the horcrux in the cave..and DD helped harry retrieve the horcruz but gave his life, and well died at the hands of Snape and not the poision that was slowly eating into him! Snape, DD had trusted... and knew that Voldy believed to be on his own side ... and by dying at hands of Snape, or more requesting SNape , was to fool Voldy that Snape had done and in turn ... beat Voldy at his own game... that DD didnt die in the hands of Voldy or his evil magic, but one he trusted and supported the good... It was the curse Avada Kedavra that Snape , his trusted man, cast at his own request that killed him, and not the poision that Voldy had used to protect the horcrux... which is a deafeat in itself for Voldy... and compunded by the fact that the Horcrux, a clue to the rest of the horcruxes was also retrieved....
Sareeta ji, i really really like what you had wrote there... Let me comment on it later on, will give in my thoughts first...
I couldn't see the topic name but I'm assuming the DOTW is "Did DD deserve to die?", right?
I don't think that it's about him 'deserving' to die or not..... he did not deserve to die, yes, but he had to... as much as it pains for me to say it.... I was always quite adamant about his death, and i always said why did he have to die and so forth and I felt terrible after he died.. but, it had to happen, didn't it? If Dumbledore is still in DH, what will Harry do? Like members before me have said, DD has been a guiding light for Harry, has guided him to go everywhere, and up until OoTP/HBP we never thought anything will happen to Dumbledore, because of course, he is the only one who Voldy feared and he's always stood by Harry's side as his protector and guider so we never actually thought anything would happen to him...
But yes, like others have said, we see in HBP how much DD has actually aged... he is unable to do many more things now... he leaves the school more often and we see so many times how he is so tired, how he is really becoming just an adviser to Harry.. and we even learn so, so much more about Voldy in the book, which indicates that DD is trying to give Harry as much information as he can before anything happens.... so yes, it probably had to happen... now, in DH, i hope there is someway for Harry to actually try and communicate with DD. Is that possible? I had said before that hopefully through the portraits in the Headmaster's office (that is, if Harry goes back to Hogwarts, which i hope and am sure he will) he may get to converse with DD periodically...
Now, onto Sareeta ji's comment above... it's really put very well, and so it Maurauder's post..!! (I'm so sorry, i dunno your name, i think i did before but i must have forgot cholly!!)
Like you have said, DD died at his own request.... we could say that Dumbledore said "Severus... please..." either to tell him to not kill him, or to allow him to do so... either way, DD was not killed by Voldy, which i think would have been a much greater defeat for DD and Harry too, because the guilt then would be much greater...
and that's my two cents😉 if i have more will definitely add!
Lovely topic griffy ji!!😃
