“At that moment, Harry fully understood for the first time why people said Dumbledore was the only wizard Voldemort had ever feared. The look upon Dumbledore's face as he stared down at the unconscious form of Mad-Eye moody was more terrible than Harry could have ever imagined. There was no benign smile upon Dumbledore's face, no twinkle in the eyes behind the spectacles. There was cold fury in every line of the ancient face; a sense of power radiated from Dumbledore as though he were giving off burning heat.”
“Killed?" said Hagrid loudly, staring down at Harry. "Snape killed? What're yeh on abou', Harry?""Dumbledore," said Harry. "Snape killed... Dumbledore.”
“And Harry remembered his first nightmarish trip into the forest, the first time he had ever encountered the thing that was then Voldemort, and how he had faced him, and how he and Dumbledore had discussed fighting a losing battle not long thereafter. It was important, Dumbledore said, to fight, and fight again, and keep fighting, for only then could evil be kept at bay, though never quite eradicated. . . .And Harry saw very clearly as he sat there under the hot sun how people who cared about him had stood in front of him one by one, his mother, his father, his godfather, and finally Dumbledore, all determined to protect him; but now that was over. He could not let anybody else stand between him and Voldemort; he must abandon forever the illusion he ought to have lost at the age of one, that theshelter of a parent’s arms meant that nothing could hurt him. There was no waking from his nightmare, no comforting whisper in the dark that he was safe really, that it was all in his imagination; the last and greatest of his protectors had died, and he was more alone than he had ever been before.”
“You do not seek to kill me, Dumbledore?' called Voldemort, his scarlet eyes narrowed over the top of the shield. 'Above such brutality, are you?''We both know that there are other ways of destroying a man, Tom,' Dumbledore said calmly, continuing to walk towards Voldemort as though he had not a fear in the world, as though nothing had happened to interrupt his stroll up the hall. “Merely taking your life would not satisfy me, I admit —''There is nothing worse than death, Dumbledore!' snarled Voldemort.'You are quite wrong,' said Dumbledore, still closing in upon Voldemort and speaking as lightly as though they were discussing the matter over drinks. 'Indeed, your failure to understand that there are things much worse than death has always been your greatest weakness'.”
“The idea of Dumbledore's corpse frightened Harry much less than the possibility that he might have misunderstood the living Dumbledore's intentions.”
“Professor Dumbledore. Can I ask you something?" "Obviously, you've just done so," Dumbledore smiled. "You may ask me one more thing, however." "What do you see when you look in the mirror?" "I? I see myself holding a pair of thick, woolen socks." Harry stared."One can never have enough socks," said Dumbledore. "Another Christmas has come and gone and I didn't get a single pair. People will insist on giving me books."It was only when he was back in bed that it struck Harry that Dumbledore might not have been quite truthful. But then, he thought, as he shoved Scabbers off his pillow, it had been quite a personal question.”
“Draco, do it, or stand aside so one of us -" screeched the woman, but at that precise moment the door to the ramparts burst open once more and there stood Snape, his wand clutched in his hand as his black eyes swept the scene, from Dumbledore slumped against the wall, to the four Death Eaters, including the enraged werewolf, and Malfoy."We've got a problem, Snape," said the lumpy Amycus, whose eyes and wand were fixed alike upon Dumbledore, "the boy doesn't seem able -"But somebody else had spoken Snape's name, quite softly."Severus ..."The sound frightened Harry beyond anything he had experienced all evening. For the first time, Dumbledore was pleading.Snape said nothing, but walked forwards and pushed Malfoy roughly out of the way. The three Death Eaters fell back without a word. Even the werewolf seemed cowed.Snape gazed for a moment at Dumbledore, and there was revulsion and hatred etched in the harsh lines of his face."Severus ... please ..."Snape raised his wand and pointed it directly at Dumbledore. "Avada Kedavra!”
