Albus Dumbledore in Harry Potter and the Deathly Hallows chapter 35: King’s Cross, by J.K. Rowling Thursday Jul 14 11:22am

I admit I am vain enough to prefer a quick, easy end, rather than the prolonged, messy affair it is likely to be if, say, Greyback is involved … or dear Bellatrix, who likes to play with her food before she eats it.

I’d say that it’s one short step from ‘wizards first’ to ‘purebloods first’ to ‘Death Eaters’. We’re all human, aren’t we? Every human life is worth the same, and worth saving. Kingsley Shacklebolt responding to the question, “Should it be wizards first?” in Harry Potter and the Deathly Hallows chapter 22: The Deathly Hallows, by J.K. Rowling Tuesday Jul 12 04:57pm
