Harry Potter is for little girls and losers. The only reason I know that's where you got it is because my little sister forced me to watch it. She was crying because she didnt want to go alone.
Although about killing him...
I dont think you can, send him to live in the sun protecting a powerful item and he wont bother you again.

Maybe tonight we'll fly so far away... We'll be lost before the dawn...
