dumbledore knows everything well not everything but he is wise and very intelligent but i think he doesn't know what is going to happen i thiink just as everyone else he will have to wait and see.but if he does know he will wait for the right time to tell harry.now do you think dumbledore will tell harry who is going to win when harry has just found out the prophecy i think not.he will wait for the right moment. its not like he hiding it everything will come in good time.dumbledore knows the confusion that is going on in ahrry's mind and does not want to worry harry.now what if knows harry will die that would be totally different harry will be confused to cauious to live his life and worry about his friends so we should consider that what dumbledore is doing is right.he is after all dumbledore.....the wise........the humble........THE GREAT!
