JKR at Edinburg festival

[jeanico2000]

I'd love to be able to debate some of the issues brough up by JK in 
the Q&A session with other adult HP fans. I was a bit confused when 
I read the following:
"If you want to speculate on anything, you should speculate on these 
two things, which will point you in the right direction. The first 
question that I have never been asked—it has probably been asked in 
a chatroom but no one has ever asked me—is, "Why didn't Voldemort 
die?" Not, "Why did Harry live?" but, "Why didn't Voldemort die?" 
The killing curse rebounded, so he should have died. Why didn't he? 
At the end of Goblet of Fire he says that one or more of the steps 
that he took enabled him to survive. You should be wondering what he 
did to make sure that he did not die—I will put it that way. I don't 
think that it is guessable. It may be—someone could guess it—but you 
should be asking yourself that question, particularly now that you 
know about the prophesy."
I just can't wrap my brain around this. Any thoughts?
Also, I really wish that JK would stop hinting that Harry might not 
survive the series like it's some kind of big inside joke or 
something. How she ends the series is ultimately her decision, but I 
find that she shouldn't tease people about the possibility. IMHO, 
Harry is by now such a beloved character that I think the 
psychological impact if she killed him off would be truly devasting. 
What say you?
