Being a goblin, Griphook severely distrusted wizardkind and hated wizarding arrogance, stemming from the fact that goblins had been treated brutally by wizards in the past.
Griphook is surprised by the respect Harry and Hermione show to non-human magical creatures. Grateful to Harry for saving his life, Griphook eventually agrees to help the trio break into Gringotts. In exchange for his services, he demands Godric Gryffindor's Sword.
In Deathly Hallows we reconnected with Griphook. He hadn't teamed up with Voldemort or betrayed anyone - he was on the run and helping Ted, Tonks's father. The goblins wouldn't bow to the so-called superiority of the wizards now in charge of Gringotts.
When the Boy Who Lived needed Griphook's help to break into Gringotts Wizarding Bank, the goblin demanded the sword of Gryffindor as payment. It was then that Harry learned that, according to Griphook, the sword rightfully belonged to his people, and his culture saw Gryffindor as a thief.
Throughout the history of the wizarding world, there had been rebellions where the goblins had fought against discrimination and prejudice. They were still considered subservient in the minds of most wizards, and they were forbidden by the Ministry from carrying wands, which had led to deep-seated resentment.
Goblins had a somewhat ambivalent relationship with orcs and half-orcs, whom they'd work with on occasion, but the only true allies of the goblin race were worgs, who often acted as mounts and fighting companions for goblins. Goblins had particularly adverse relations with dwarves, gnomes, and Tel-quessir.
According to Amos Diggory, it was worded "No non-human creature is permitted to carry or use a wand", meaning that any magical beings other than witches and wizards, such as giants, goblins, vampires, hags, and house-elves, were forbidden from owning or using wands of their own.
When another goblin revealed what had transpired, Voldemort flew into a rage. He slaughtered all within the room, including Griphook, who fell to the ground holding the Sword. Moments later, Voldemort stepped over his corpse, and the Sword faded away to return to the Sorting Hat.
They know she's an impostor. They've been warned", so obviously the request for the wand was unexpected even to him. It's thus pretty safe to conclude that the real Bellatrix had reported her wand stolen and alerted Gringotts prior to the trio's attempted break in.
When Ginny Weasley, Neville Longbottom, and Luna Lovegood tried to steal the sword from the Headmaster's office, Snape gave the Sword of Gryffindor to Bellatrix Lestrange for safe keeping. Bellatrix hid the sword at Gringotts, alongside other important artifacts: mainly, the Cup of Hufflepuff.
At some point in time, Lord Voldemort gave Bellatrix Lestrange Hufflepuff's Cup, one of his Horcruxes, to keep safe in her vault, though he didn't tell her its true nature.
This massacre occured at Malfoy Manor on 1 May 1998. Numerous Gringotts goblins were slaughtered after informing Voldemort of the theft of Hufflepuff's Cup.
He sobbed openly when he saw Cedric had died and when he was interviewed about his son's death, but at least didn't blame Harry for it, and contrary, believed Harry's claim of Voldemort's return and thanked him for returning Cedric's body.
Dumbledore consistently shows favoritism towards Gryffindor, overlooking bad behavior and allowing rule-breaking without consequences. While it may seem like bias, Dumbledore's favoritism towards Gryffindor stems from the knowledge of Harry's role in fulfilling the prophecy and his need to prepare him for his future.
Griphook, impressed by Harry's respectful treatment of the house elf, agreed to help on the grounds that he would be given the real sword as payment. Harry reluctantly agreed to this demand. When their break-in was discovered, Griphook seized the real sword and ran with it.
Honestly, Hermione knew Dobby was a lost case... nothing could have revived Dobby after the attack or she would have definitely helped Harry with Dobby considering she was the girl who started S.P.E.W(Society for the Elfish welfare) and fought for elf rights. There was nothing to be done at that point.
Why didn't Lucius Malfoy want to give Voldemort his wand?
After no volunteers presented themselves, Voldemort selected Lucius as an unwilling donor. Lucius reluctantly surrendered his wand after some prompting from his wife, identifying its wand wood and core for Voldemort's benefit.
When Death Eater Bellatrix Lestrange killed Harry's godfather Sirius Black, Harry chased down Bellatrix and performed the curse on her out of rage. However, it was performed unsuccessfully as Harry was doing it with "righteous anger" and couldn't muster the will to actually cause her harm.
Due to his humiliation in the Triwizard Tournament, Cedric eventually becomes a Death Eater and kills Neville Longbottom. Due to Neville's death, the final Horcrux Nagini was never destroyed, and as a result Voldemort is never defeated, kills Harry and takes over the Wizarding World.
What happened to the sword after Griphook took it?
Laura Voldemort killed all the Goblins for letting Harry, Ron and Hermione escape with one of his horcruxes so when Griphook was dead, the sword went back to where it came from: the Sorting Hat.
Death. Fifty-three years after his defeat, Grindelwald was slain in his prison cell by Lord Voldemort, who was searching for the Elder Wand for himself. It was only during the confrontation in Grindelwald's cell that Voldemort learned Albus Dumbledore had claimed the wand long ago.
Wandless magic could also be performed nonverbally, but this increased the level of difficulty to the point that only practitioners of exceptional skill could perform more than the most basic magic. Albus Dumbledore, generally considered the greatest wizard of all time, was known for performing magic in this manner.
in the harry potter universe its stated wandless magic is weaker though in this game natty states in uganda they only use wandless magic and it was about the same in power. so really it comes down to the user.
J. K. Rowling stated that wands with Thestral tail hair cores can only be mastered by those who can accept death. Therefore, it would seem impossible for someone like Voldemort, who was obsessed with immortality and therefore unwilling to accept death, to ever master the Elder Wand.
