Please bear with me and read through till the end, I think a lot of 
people would agree with my first few points but I want to know what 
you think about points 3 and 4!

Taken from Harry Potter Lexicon: "The term "Horcrux" is used to refer 
to any object in which a person has concealed a part of his or her 
soul. The object need not be inanimate; according to Dumbledore, a 
living creature can be used as a Horcrux, although it is risky to do 
so since the Horcrux in such a case is something that can move and 
think for itself, independently of the implanted fragment of soul." 

1) Harry's scar is a Horcrux
CoS- "Voldemort put a bit of himself in me?" Harry said, thuderstruck.
"It certainly seems so." (DD)

GoF- "Because you and he are connected by the curse that failed, "
said Dumbledore. "That is no ordinary scar."

Other supports for this theory taken from Harry Potter Lexicon:
LV wants a relic of each founder and harry is probably a Gryffindor 
decendant.  
The murder of Harry's parents was a significant murder and LV might 
want a "trophy" from that murder.  
Harry is a parseltoungue.  
LV possesses Harry in OP.  
Killing curses do not leave scars.  
No one tries to kill Harry besides LV- he wants him alive.

2) Because Harry's scar is a Horcrux (which will realize near the end
of book 7) , he is stuck with having to destroy himself in order to
kill Voldemort.

3) Harry, after much thought, decides he is willing to go through
with this as he understands that in sacrificing himself he will be
saving millions of wizard lives. Out of love he will go through with
his suicide.

4) However... it is not his sacrifice that will kill Voldemort. At
the moment Harry is about to kill himself, Voldemort will die! By
making the selfless choice out of love, Voldemort will be defeated.
Harry will not have to go through with the sacrifice and he will not
have to kill Voldemort in some other way and possibly face going to
Azkaban. The intense love of being willing to complete such an act
will be enough to destroy Voldemort.

How would that be for an ending?!
