Dumbledore wanted Voldemort to destroy the part of his soul which was in Harry's scar. If Voldemort was the one to fire the Killing Curse then he would destroy his own soul instead of killing Harry. Making Harry accept death was likely so that he wouldn't be dodging the Curse or defend himself in any other way.

He didn't survive thanks to being the master of the Deathly Hallows, since that doesn't prevent death.

It is indeed true that the books are 100x better than the movies.
