Cedric's death is a major plot point in the stage play Harry Potter and the Cursed Child, in which Harry and Ginny Weasley's son Albus uses a Time-Turner and prevents Cedric's death. Due to his humiliation in the Triwizard Tournament, Cedric eventually becomes a Death Eater and kills Neville Longbottom.
Seething with fury at his humiliation, Cedric ended up joining the Death Eaters come Voldemort's return. As a result, during the Battle of Hogwarts, Cedric Diggory killed Neville Longbottom before he could destroy Nagini, thus keeping Voldemort immortal and allowing him to kill Harry Potter.
More importantly, Cedric was a kind and loyal person. After catching the Snitch in a match against Gryffindor in Harry's third year, he offered to replay the game since Harry was unwell. He never got angry at Harry for becoming the second Hogwarts champion and remained friendly even when most of the school didn't.
On a second trip back to 1995, Scorpio and Albus inadvertently humiliate Cedric with an engorgement spell that puts him out of the running for the cup.
For the simple answer: Cedric had to die simply because he was an inconvenience to Voldemort. Voldemort set up a very direct plan to be “reborn”, and he needed Harry. Cedric was not supposed to come along, so like Voldemort always does, he just got rid of him.
Cedric's death serves to highlight Voldemort's casual inhumanity, his disregard for the value of human life other than his own. It also displays Wormtail's weak personality, in that he is clearly willing to take Cedric's life without question or cavil on the orders of Voldemort.
While Harry is suffering through searing pain through his scar due to the Horcrux in his body responding to Voldemort's presence, Voldemort orders Pettigrew to "kill the spare", prompting Pettigrew to use the Killing Curse on Cedric.
In the book, he provoked Harry and his friends by actually liking the fact that Cedric Diggory died and that according to him, mourning for Cedric is a big waste of time. That is one of my least favorite Draco Malferret moments.
He didn't think it was fair that Cedric was killed the night of the Triwizard Tournament, and all he wants to do now is bring Cedric back to his father. So when Albus returns to Hogwarts, he tells his best friend, Scorpius Malfoy, what he wants to try to do.
(That's Cedric.) It has long been accepted that Peter Pettigrew aka Wormtail kills Cedric on the orders of Voldemort, and the movie adaptation of JK Rowling's fourth book runs with this without question.
The advantage of nonverbal casting is that you don't relay any info to your opponent. If you start shouting an incantation, the opponent has a split second to parry your spell or block it using a specific counterspell. The Avada Kedavra curse, however, cannot be blocked, so you gain nothing by casting it non-verbally.
Amos thanked Harry for returning Cedric's body, and assured him that they did not blame Harry for his death. Harry tried to give them the prize money that came with winning the tournament, but they refused it.
However even though he was brave, he did not possess the type of courage that goes well with showboating. Rather this Badger showed the essences of being in Hufflepuff. Fair, loyal, compassion and even became collateral damage of the Tri Wizard Tournament. Despite it all though he never spoke highly of his works.
Weaknesses. Although Cedric is honest and hardworking, he occasionally demonstrates a certain lack of ingenuity, initiative, and drive, though this changes as he competes in the Tournament.
As of "In Cedric we Trust", Wormwood betrayed Cedric due to the fact that the sorcerer is no longer evil and plotting, and that Wormwood misses the "Old Cedric".
“Yes” according to Harry at the time, who until later into the tournament didn't think he had any chance of winning and only hoped to survive. Cedric was the top of his year, almost like Hermione with three more years of Hogwarts study. Cedric's knowledge of magic was clearly much superior.
Though the Sorting ends up plaguing Albus Potter all through school as the only member of his family to set foot in Slytherin, he's there for a reason. And that reason has nothing to do with lineage or attributes or inclination. He just wanted to spend all of his time with Scorpius Malfoy. So he did.
Much of the plot hinges on Harry's tumultuous relationship with his son, Albus — a relationship that culminates in Harry saying, “Sometimes I wish you weren't my son!” And I knew, in my heart of hearts, that Harry would never say that. He just wouldn't.
They Were On Opposing Quidditch Teams
And while Harry is only depicted as a sore loser if Draco Malfoy is involved, he may feel less inclined to be friendly toward Cedric after the latter caught the snitch, giving Hufflepuff a win during Harry's third year.
Having gone through the horrors of the second wizarding war as a Death Eater, Draco abandoned the pure-blood beliefs he was originally devoted to, and grew to become a better person than he was in his youth, growing more tolerant and accepting of the non-pure-bloods of the wizarding world.
In an interview, Rowling described Snape's character as an "antihero". She has said that she drew inspiration for Snape's character from a disliked teacher from her own childhood, and described Snape as a horrible teacher, saying the "worst, shabbiest thing you can do" as a teacher is to bully students.
He was more jealous of Harry than he let on
It was easy to miss because Draco didn't often show his emotions, modelling himself on his cold, confident, calculating father, but J.K. Rowling has confirmed that a lot of his enmity towards Harry stemmed from envy.
At the battle of Hogwarts, Cedric killed Neville before he killed Nagini.
Though his motives may speak otherwise, Cedric is not truly evil. He desires power merely to prove to those that mock him that he is capable of greatness and it has been revealed that Cedric is very much aware and hurt by how poorly others regard him.
“Take my body back to my father.” This quote is certainly a sad one to end on, because these are Cedric Diggory's last words. While Harry Potter duels Voldemort in a graveyard, Cedric's corpse lies by the portkey, both discarded as useless objects by the Dark Lord. But then Harry's spell does something extraordinary.
