Why did Voldemort die though he had Harry's blood?

[pooja khurana]

No: HPFGUIDX 177321

The soul connection breaks the 1st time between Harry and 
LV but they are still bound by blood.I percieved that LV 
was killed inspite of the blood protection as he had the 
sacrifical blood in him. Harry's mother sacrificed herself, 
Harry himself sacrificed to save the wizard world and now 
it was LV turn to sacrifice himself unknowingly though. It 
is in the nature of that blood to sacrifice itself. Also we 
cannot overlook this fact that now  Harry is the master of the 
hallows cannot be killed at all no matter what. The elder wand 
cannot be used against Harry as he is the rightful master of it. 
The stone he uses not to bring dead back to life but to help him 
come to terms with his own death. Cloak has become a part of his 
life and he has become the master of deathly hallows.But according 
to the profecy one has to die.Though it is really difficult to 
overpower Voldemort by just expelliarmus but as the wand belongs 
to Harry he disarms Voldemort and the spell spoken by Voldemort
 rebounds back on him.The blood connection adds to the destruction 
of LV. The master of the 3 hallows that is Harry has become 
immortal and Voldemort is mortal so it is natural that Harry 
would survive the killing curse again. LV who is always in 
constant fear of death without his horcruxes and being the 
possessor of sacrifical blood now dies and his plan of 
overpowering the enemy by taking his blood brings his downfall. 
So Harry's blood increased the chances of LV to die as in HP4 
Dumbledore smiles when he comes to know that Harry's blood has 
been taken.
