Good versus Evil Quotes in Harry Potter and the Deathly Hallows
How we cite our quotes: Citations follow this format: (Chapter.Paragraph)
"Hide them all, then," he croaked. "Keep her – them – safe. Please."
"And what will you give me in return, Severus?"
"In – in return?" Snape gaped at Dumbledore, and Harry expected him to protest, but after a long moment he said, "Anything." (33.129-130)
Here, we see the moment of Snape's shift from evil to good – his betrayal of Lord Voldemort because of Lily's endangerment demonstrates the power of his love over his desire to serve the Dark Lord.
"And his knowledge remained woefully incomplete, Harry! That which Voldemort does not value, he takes no trouble to comprehend. Of house-elves and children's tales, of love, loyalty, and innocence, Voldemort knows and understands nothing. Nothing." (35.26)
Again, the difference between Harry's understanding of the world and Voldemort's is made clear – Voldemort is completely consumed by his lust for power, and his ignorance of the things that actually make life good and worthwhile are what really demonstrate his true evil.
"Master of death, Harry, Master of Death! Was I better, ultimately, than Voldemort?"
"Of course you were," said Harry. "Of course – how can you ask that? You never killed if you could avoid it!"
"True, true," said Dumbledore, and he was like a child seeking reassurance. "Yet I to sought a way to conquer death, Harry."
"Not the way he did," said Harry. […] "Hallows, not Horcruxes." (29)
Again, the question of ends vs. means arises – if Dumbledore and Voldemort had the same goal in mind, does it even matter that they worked towards it in different ways? Harry reassures Dumbledore that it does… what do you think?
