Actually, I can see a certain amount of potential here:
"Harry, you must kill Lord Voldemort. You are the only one who can!"
"NO! My dad says that's it's wrong to kill."
Let's see how Dumbledore, with all his second chances and offers of redemption to the Dung Eaters, reacts when he meets someone with a moral code that makes his look tawdry -- which, IMO, it is.
But that doesn't mean that Moldieshorts has to get off scot free... There's more than one way to deal with Tommy-boy, as shown by a rather good story I've read that crosses HP with UNIT -- not the Doctor, "just" an expanded UNIT, headed by "the Brig" (he's a General by then, but everyone still calls him the Brig).
And I just had an
evil idea... Let's send Tommy-boy to New Krypton (
sans wand, of course). He'll spend most of his time just trying to survive under the heavy gravity and red sunlight (Vitamin A and D deficiencies, anyone?), and they'll have to put up with him and won't be able to get rid of him because he'll keep shorting out the electrical systems of their ships (and, if they're unlucky, of their life support systems on that rock, too).
How sad.
Boo-hoo.
Phil, more than happy to get out his OLL&BC hat to deal with ol' Moldie, the ferrets and Snivellus...
