What does snape do for voldmort to kill him?

Answer 1

I think he kills professor snape because he Volermort wanted Draco Malfoy to kill Dumbledore in the 6th film, but snape did instead so he Voldermort might of got a bit angry.

I don't know if that's right or not,

NO THAT IS NOT RIGHT (I WILL CORRECT YOUR ANSWER : BY (AHMED NASSAR)

I'm really sure that voldemort thought that snape disarmed dumbledore

but Draco did it

so voldemort thought that snape is the new owner of the elder wand.

so voldemort disarm and kill snape

OK, actually, THIS is why Voldemort Killed Snape (!!!!!):

In the Half Blood Prince, Malfoy disarmed (expelliarmus) Dumbledore, and Snape killed him. Whoever disarmes/kills the owner of the Elder Wand is the new owner of the Elder Wand. Dumbledore was the owner of the Elder wand until he was killed. Since Voldemort wanted the Elder Wand for himself, he figured that since Snape killed Dumbledore, Snape was the owner of the Elder Wand, Voldemort thought that if he killed Snape, Voldemort would be the owner of the Elder Wand. HE IS AN IDIOT!!!!!! THAT is the truth. ( believe me, I am the most obsessesd Harry Potter fan you will ever know. It is my JOB to know these things!!!)

Answer 2

Voldemort believes that Snape is the owner of the Elder wand - a wand that cannot lose in a duel - because he wants the wand.

The wand can only change masters if you dissarm or kill the previous owner.

Voldemort, of course, doesn't care about betraying Snape - who, as far as Voldemort knows, is still loyal to Voldemort.

Answer 3

Voldemort commanded his giant snake, Nagini, to kill Snape. The snake bit his neck and he bled to death.
