I'm going to keep going until I succeed — or die. Don't thin... - J.K. Rowling, Harry Potter and the Deathly Hallows

"Would you like me to [kill you] now?"asked Snape, his voice heavy with irony. "Or would you like a few moments to compose an epitaph?"

"He felt his heart pounding fiercely in his chest. How strange that in his dread of death, it pumped all the harder, valiantly keeping him alive. But it would have to stop, and soon. Its beats were numbered. How many would there be time for, as he rose and walked through the castle for the last time, out into the grounds and into the forest?"

"But you're dead,' said Harry.'Oh, yes,' said Dumbledore matter-of-factly.'Then... am I dead too?''Ah,' said Dumbledore, smiling still more broadly. 'That is the question, isn't it? On the whole, dear boy, I think not."

"Do not pity the dead, Harry. Pity the living, and, above all those who live without love."

"Harry, you wonderful boy, you brave, brave man."
