It's been almost ten years since we saw the triumph of Harry Potter and co. and the imminent downfall of Lord Voldemort in Harry Potter and the Deathly Hallows, but true love never fades. Besides, ever since the announcement of Fantastic Beasts and Where to Find Them my love of the magical world created by J.K. Rowling is at an all-time high.
As an author, Rowling is known for being extremely thorough and deliberate in all of her works. And as her readers, we've all learned to keep an eye out for the importance in what may seem like even the most insignificant detail.
A few years ago, Ryan Smith posted a keen observation to a Quora forum. While there's no doubt that Harry, Ron, and Hermione played integral roles in the death of Lord Voldemort, Smith suggest that he unknowingly created all of the tools necessary to his demise.
He rightly points out that each of Lord Voldemort's horcruxes were destroyed by a different wizard and posits that the Dark Lord enabled each of their destructions. Here's a broken down version of Smith's points:
1. Tom Riddle's Diary
We all remember when Harry destroyed Tom Riddle's enchanted diary with the Basilisk fang. What we didn't know at the time was the fact that the diary was a horcrux, and that by opening the Chamber of Secrets, Voldemort gave his enemies the means to destroy five of the seven Horcruxes.
2. Marvolo Gaunt's Ring
Before dying at the hands of Severus Snape, Dumbledore was able to destroy Marvolo Gaunt's ring with the sword of Godric Gryffindor. The thousand year old goblin-made sword owned by the Gryffindor House founder was able to take on the power of substances it touches.
Since Basilisk venom can destroy horcruxes and the Sword of Gryffindor killed the gargantuan serpent, it gave it the ability to also destroy the hidden fragment of Voldemort's soul.
3. Salazar Slytherin's Locket
Although it was no easy task, Ron Weasley was similarly able to use the sword of Gryffindor to vanquish Salazar Slytherin's locket as well as the image of Harry and Hermione making out from his mind.
4. Helga Hufflepuff's Cup
Like the diary, Hermione destroyed Helga Hufflepuff's cup with the Basilisk fang in the Chamber of Secrets. This also brought us to one of the most highly-anticipated kisses in the film franchise!
5. Rowena Ravenclaw's Diadem
Vincent Crabbe may have accidentally obliterated Rowena Ravenclaw's diadem in the Room of Requirement, but he wouldn't have been able to do so had it not been for the Dark Lord himself. If you remember correctly, it was Crabbe's unmanageable Fiendfyre spell that got the deed done. Now how would someone like Crabbe, a largely incompetent wizard, learn this difficult spell?
Well, Voldemort's Death Eaters, the Carrows, who taught at Hogwarts in his seventh year were more than happy to teach him the piece of dark magic. Had they never been appointed to the teaching positions, Crabbe may have never learned the spell and inadvertently destroyed the horcrux.
6. Harry Potter
After being foreseen in Professor Trelawney's prophecy we all knew that neither Voldemort nor Harry could live while the other survived and that one of them would have to kill the other. Of course, Voldemort didn't know that by using the killing curse on Harry he was destroying the Horcrux he created by accident in Godric's Hollow.
Finally, we all cheered when Neville Longbottom lived up to his full Gryffindor potential and severed Nagini, Lord Voldemort's remaining Horcrux, with the sword of Gryffindor. Which, as we now know, may not have been possible had it not been for the power of the Basilisk venom it took on.
Personally, I think Ryan Smith makes a fantastic argument for his observation. One of the biggest factors that let to Lord Voldemort's death was himself! Granted, there may have been other means to destroy a Horcrux than with the Basilisk fang or the Sword of Gryffindor, but these certainly made it easier.
