Why did Voldemort want it if he already had the horcurches??
And what would happened if he had had the stone??
Finally why in the 4th book he says that with the stone he would have immortality?
Answer: The stone was need for his own body. I think that he mean by immortality and the death eaters wasn't know his horcruxes. He can't say about them.
Voldemort wanted the Philosopher's Stone because his body had been destroyed by the rebounding Killing Curse at the Potters' murder. If he had the stone, he would have somehow been granted a body earlier and would have went on killing until Harry stopped him. And in the fourth book he says with the stone he'd be immortal, because he'd have had his body back, his horcruxes to support him, and the Elixir as a backup plan. Also, note that the Death Eaters didn't know about his Horcruxes, so he couldn't reveal that to them - what if one defected, as one of them did? Essentially, the same answer SirChrisMorris gave, except more detailed and with less grammar errors (no offence to SirChrisMorris). james (talk) 16:37, August 31, 2012 (UTC)
