Why did Lord Voldemort need unicorn blood?

Answer 1

Unicorn blood will save anyone an inch from death. Voldemort makes Professor Quirrell drink the blood to keep him alive, however at a high price. Slaying something as pure as a unicorn brings the drinker a cursed life. Voldemort does not care as the only thing he fears is death.

Answer 2

Note: He only had made 6 horcruxes at that point, and believed he only had made 5.

The horcruxes kept him alive, but didn't give him a body. More like a kind of ghost existence.

Answer 4

When drunk, unicorn blood will keep the person alive.

When Lord Voldemort attempted to murder Harry Potter, the curse backfired. However as Voldemort had already created five of his Horcruxes he could not die, but his body could. Having just killed Lily Potter, Voldemort's soul had once again split. That part of his soul attached itself to the only living thing in the house (Harry) and whatever was left of Voldemort fled. He was extremely weak and only just managed to survive.

In 1990 he met Professor Quirrell and they began planning to steal the philosopher's stone. As a temporary measure, Voldemort was drinking unicorn blood until he could use the Elixir of Life.

Answer 5

When Lord Voldemort failed to kill Harry Potter, the curse rebounded and killed his body. However, as he had already created several Horcruxes Voldemort did not entirely die. Instead, he was left without a body and spent many years barely alive until he was found by Professor Quirrell. Together they planned to steal the philosopher's stone.

To keep him strong enough until then Voldemort drank the blood of a unicorn which can save someone who is even an inch from death.
