Well, in the movie, Neville destroyed one of the horcruxes, Nagini, which was Voldemorts snake, which made Voldemort mortal again. But since the elder wand, which was the wand that Voldemort was using when he was dueling with Harry, belonged to Harry since in the sixth book Draco disarmed Dumbledore but in the seventh movie part 2, Harry disarmed Draco in the room of requirement, so the elder wand became Harrys. Therefore, when Voldemort tried to use the unforgivable curse, Avada Kedavra, on Harry it backfired on him because Harry was the owner of the wand therefore any curse used against him with that wand would not work and would backfire to the person holding his wand. So, Voldemort ended up killing himself but Harry sort of helped because the wand belonged to him and the spell rebounded off of him. So Neville didnt kill Voldemort but helped in the process of doing it.

Charles William Nevill died in 1888.
He doesn't die. The people who say he does are idiot's. The reason they told you that is probably didn't read the whole book and were looking for an interesting chapter at the end and hear that he's dead. What really hap pends is when harry was hit with the "Aava Kadabra" Curse when he was a baby he got some of voldermourt's soul so he thought he had to die so that voldermourt would die too. So he let voldermourt hit him with a killing curse, what happend was voldermourt didn't kill Harry but his soul inside of Harry. However Harry did have to chose to live or to die and he chose to live.
