Why can't Voldemort kill Harry Potter?

Whether Voldemort can kill Harry Potter depends on how J.K. Rowling writes. It is said that the author intends to let Harry and Voldemort die together, but under the pressure of fans, the fate of the characters in the novel is out of the author's control. Let me answer your question. Voldemort finally confronted Harry Potter twice: the first time he didn't kill him, and the second time he failed.

Voldemort has seven horcruxes, so he can destroy seven. Harry Potter is Voldemort's sixth horcruxes, and Neville's snake killed with Gryffindor sword is the seventh.

When Voldemort killed Harry Potter in the forbidden forest, he only destroyed his soul film on Potter. What doesn't hold water is that the default at the beginning of the book is that only destroying horcruxes can destroy the soul membrane.

Voldemort's horcrux unintentionally made on Harry Potter was also doped with Harry's mother's love curse. Voldemort's body was remolded with Harry's blood (in the fourth Goblet of Fire), so this is also part of the immortal factor (the protection of mother's love curse and Voldemort's own blood relationship with Potter).

Harry Potter took away the Deathly Hallows when he went to the Forbidden Forest, and he was the only one who collected these three things (it should be said that Dumbledore had already collected them, but he returned the invisibility cloak to Harry in the first part and gave the Resurrection Stone to Harry in the sixth part). If you know the legend of the Deathly Hallows and the dialogue with Dumbledore in Harry's mind after he was "killed" (I personally think Dumbledore put it on him), however, this statement is not true: regardless of the immortal legend, the Deathly Hallows, Harry let the Resurrection Stone fall to the ground a few minutes before he was killed and walked forward for a few minutes without him.

Then when the forest was closed, the connection between them was broken. At this time, life and death depend on the power of magic. Why can't Harry Potter be killed?

This has something to do with wands. Voldemort thought the wand in his hand was an elder wand, but in fact he forgot that Malfoy finally defeated Dumbledore, not severus snape, and Malfoy was defeated by Harry. So Harry is the owner. So when Potter uses the spell "except your weapon", the effect will be stronger than Voldemort's spell "Abada killed me", so the former works, so Voldemort's wand will be handed over, and the latter can only bounce back when it doesn't work, so it can be said that he killed himself.

Rowling's ending is actually far-fetched Death is the best ending.
