Dumbledore's gleam (again!)

First of all, I believe that Voldemort made some horrendous mistake 
when he used Harry's blood to revive himself, thus Dumbledore's gleam.

I looked at a few of the old "Dumbledore's gleam" topics, but didn't 
see any of them tie it in with Peter Pettigrew.  That's the route I'm 
going to go - I hope it hasn't been done to death before.

In PoA, Dumbledore says that Harry will be very glad someday that he 
saved Pettigrew's life.  Now, if Harry HADN'T saved Pettigrew, then 
Voldemort would not have been revived in book 4.  That's a REALLY bad 
consequence of his showing mercy.  If Harry is someday gonna be glad 
of this act, then whatever Peter does, it's gonna have to outweigh 
Voldemort's revival.  The only thing I can think of is that Peter 
will have a hand in permanently destroying Voldemort.

"Flesh of the servant willingly given, blood of the enemy forcibly 
taken."  I find it very interesting that the "faithful servant" that 
donates the flesh owes a life-debt to the "enemy" that donates the 
blood.  Perhaps this fact will prove central to how Voldemort is 
ultimately vanquished?  For instance, if Pettigrew shows loyalty in 
some fashion to Harry over Voldemort, would this weaken Voldemort in 
some way?

Now, Dumbledore does not get the gleam in his eye until he finds out 
that Voldemort could touch Harry without ill effect.  Perhaps this 
fact shows that Voldemort's ritual was a complete success, which of 
course would make Voldemort worse than before (as the prophecy says 
he will be.)  But the bigger they are, the harder they fall.  Maybe 
the fact that the ritual WAS a complete success means that if 
Pettigrew betrays Voldemort for Harry, then Voldemort will be 
completely destroyed.

It doesn't make for a exciting finale (no big duel or anything), but 
I think that Harry is somehow going to destroy Voldemort with love.  
Dumbledore repeatedly says that this is what Harry has in large 
abundance, but Voldemort does not have at all.  It prevents Voldemort 
from possessing Harry.  It's GOT to come into play at the end.  
Perhaps Harry will come to understand (and pity) Pettigrew, will show 
some act of love towards him, Pettigrew betrays Voldemort for Harry, 
and the revival ritual somehow backfires on Voldemort and destroys 
him permanently.
