Shared blood

I had a thought. Because Harry and Voldemort now share blood, is it 
possible that if one dies, the other one must die too -- sort of a 
all-blood-goes-at-once theory? That would explain the famous look of 
triumph on Dumbledore's face -- even if Voldemort manages to kill 
Harry, he will die too. This would also explain Dumbledore's next 
look as well -- I believe it was saddness/tiredness (don't have  book 
4 with me right now). 
This also would make for an interesting ending of the series if Harry 
discovers the end result of the blood-tie. He could sacrifice himself 
to save the wizard world -- which means he doesn't have to use 
feelings of hate or malace to kill Voldemort (as he would need to do 
to use an unforgivable curse) but could use his feelings of love for 
those around him to end himself and save them. This doesn't mean he 
would have to fall on a sword, but he could refuse to fight Voldemort 
(in a Obi-won-kenobi lightsaber-dropping way) thereby fulfilling the 
prophecy by dying by Voldemort's hand. 
Also, this goes along with the Book 5 theme of mastering his 
emotions - he would have to master his feelings of fear and revenge 
as well as his feelings of love for his friends, to be able to allow 
himself to be killed.
