Harry Potter and the Methods of Rationality

A cold chill was coming over Harry, a chill that came with instructions to keep his voice and face normal. Note to self: Overthrow government of magical Britain at earliest convenience.

Harry coughed again to clear his throat. "Draco, please please please don't take this the wrong way, my word is my bond, but like you said I could be in Slytherin and I really want to ask for informational purposes, so what would happen theoretically speaking if I did testify that I'd heard you plan it?"

"Then if I was anyone other than a Malfoy, I'd be in trouble," Draco answered smugly. "Since I am a Malfoy... Father has the votes. And afterwards he'd crush you... well, I guess not easily, since you are the Boy-Who-Lived, but Father is pretty good at that sort of thing." Draco frowned. "'Sides, you talked about murdering her, why weren't you worried about me testifying after she turns up dead?"

How, oh how did my day go this wrong? Harry's mouth was already moving faster than he could think. "That's when I thought she was older! I don't know how it works here, but in Muggle Britain the courts would get a lot more upset about someone killing a child -"

"That makes sense," Draco said, still looking a bit suspicious. "But anyway, it's always smarter if it doesn't go to the Aurors at all. If we're careful only to do things that Healing Charms can fix, we can just Obliviate her afterwards and then do it all again next week." Then the blonde-haired boy giggled, a youthful high-pitched sound. "Though just imagine her saying she'd been done by Draco Malfoy and the Boy-Who-Lived, not even Dumbledore would believe her."

I am going to tear apart your pathetic little magical remnant of the Dark Ages into pieces smaller than its constituent atoms. "Actually, can we hold off on that? After I found out that headline came from a girl a year younger than me, I had a different thought for my revenge."

"Huh? Do tell," Draco said, and started to take another swig of his Comed-Tea.

Harry didn't know if the enchantment worked more than once per can, but he did know he could avoid the blame, so he was careful to time it exactly right:

"I was thinking someday I'm going to marry that woman."

Draco made a horrid ker-splutching sound and leaked green fluid out the corners of his mouth like a broken car radiator. "Are you nuts?"

"Quite the opposite, I'm so sane it burns like ice."

"You've got weirder taste than a Lestrange," Draco said, sounding half-admiring about it. "And I suppose you want her all to yourself, huh?"

"Yep. I can owe you a favor for it -"

Draco waved it off. "Nah, this one's free."

Harry stared down at the can in his hand, the coldness settling into his blood. Charming, happy, generous with his favors to his friends, Draco wasn't a psychopath. That was the sad and awful part, knowing human psychology well enough to know that Draco wasn't a monster. There had been ten thousand societies over the history of the world where this conversation could have happened. No, the world would have been a very different place indeed, if it took an evil mutant to say what Draco had said. It was very simple, very human, it was the default if nothing else intervened. To Draco, his enemies weren't people.

And in the slowed time of this slowed country, here and now as in the darkness-before-dawn prior to the Age of Reason, the son of a sufficiently powerful noble would simply take for granted that he was above the law, at least when it came to some peasant girl. There were places in Muggle-land where it was still the same way, countries where that sort of nobility still existed and still thought like that, or even grimmer lands where it wasn't just the nobility. It was like that in every place and time that didn't descend directly from the Enlightenment. A line of descent, it seemed, which didn't quite include magical Britain, for all that there had been cross-cultural contamination of things like ring-pull drinks cans.

And if Draco doesn't change his mind about wanting revenge, and I don't throw away my own chance at happiness in life to marry some poor crazy girl, then all I've just bought is time, and not too much of it...

For one girl. Not for others.

I wonder how difficult it would be to just make a list of all the top blood purists and kill them.
