Harry Potter (Cruciatus & Imperius Curses) He cast Imperio upon both Bogrod and Travers when breaking into Bellatrix Lestrange's Gringotts vault in The Deathly Hallows, and has used (or attempted to use) Crucio on Amycus Carrow, Bellatrix Lestrange, and Severus Snape.
Not long after, Harry Potter found himself attempting the Cruciatus Curse on his own enemies — twice (though he failed during the attempts). The first time Harry cast Cruciatus was in Harry Potter and the Order of the Phoenix on Bellatrix Lestrange after she killed Sirius Black in the Department of Mysteries.
Shortly before the Battle of Hogwarts, Harry not only successfully used the Cruciatus Curse against Amycus Carrow, he also cast the Imperius Curse against two individuals during the Gringotts heist which allowed Harry, Hermione, and Ron to get inside the Lestrange Vault.
Shortly before the Battle of Hogwarts, Harry not only successfully used the Cruciatus Curse against Amycus Carrow, he also cast the Imperius Curse against two individuals during the Gringotts heist which led to Harry, Hermione, and Ron getting in the Lestrange vault.
Hermione Granger had this curse used on her by Bellatrix Lestrange during her interrogation at Malfoy Manor in March of 1998. Harry Potter managed to successfully use it on Amycus Carrow without legal consequences as well as a result of this legalisation, shortly before the Battle of Hogwarts on 1 May 1998.
How Did Harry Use CRUCIO? (Harry’s DARKEST Book Moment NOT Shown in Movies) - Harry Potter Explained
Why did Crucio not hurt Harry?
During the Battle of Hogwarts, Voldemort used the Cruciatus Curse on what he believed to be Harry Potter's dead body as a way of dishonouring it and to show he had won. Harry felt no pain because the wand Voldemort used, the Elder Wand, refused to harm its true master.
After the Wizards' Council was reformed into the Ministry of Magic, tighter restrictions were placed on the use of certain kinds of magic. The Imperius Curse was deemed by the Ministry to be Dark magic, and, along with the Cruciatus and Killing Curses, were declared "unforgivable" in 1717.
Although it is not confirmed to have been the Killing Curse, it is highly likely that Ron attempted to kill Voldemort's snake, and last Horcrux, Nagini, with Avada Kedavra. This is because, in the movies, Ron can be seen firing out a green spell at the snake, and it looks just like the Killing Curse.
None of the good guys dare use the Killing Curse throughout the events of the movies and books, no matter how high the stakes and how difficult things are. But Ron Weasley is the exception, giving it a go in the Deathly Hallows: Part 2 movie when himself and Hermione look destined to die via Nagini.
Malfoy spots Harry and casts a Cruciatus curse; Harry, defending himself, using the Half-Blood Prince's Sectumsempra spell without knowing its effects. To his horror, it gashes Draco's face and chest, spilling his blood everywhere. Moaning Myrtle flies off, screaming.
For example, even Dolores Umbridge was capable of using the spell as she nearly cast it on Harry to gain information. Nevertheless, while the impact of Avada Kedavra was unforgettable, Crucio was far more deadly than that, and Imperio as it could make a victim beg for death solely to stop the pain.
In the final movie, Harry Potter and the Deathly Hallows pt. 2, Molly first hits Bella with a spell that freezes her, most likely Petrificus Totalus. Then, she launches another one that shatters her entire body into pieces, which could be expelliarmus, bombarda, stupefy, or any spell that can produce such an effect.
Effect. Unforgivable Curses are the three most powerful and sinister spells known to the wizarding world, and are tools of the Dark Arts. They were first classified as "Unforgivable" in 1717. They are the Killing Curse, Avada Kedavra, the Cruciatus Curse, Crucio, and the Imperius Curse, Imperio.
The Disarming Charm became Harry Potter's signature spell, and it notably caused the final defeat of Lord Voldemort during the Battle of Hogwarts by rebounding his Killing Curse, because the Elder Wand recognised Harry as its master through the spell connection, and thus strengthened the Disarming Charm to the point ...
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.
The Killing Curse was created in the early Middle Ages by Dark witches and wizards. Primarily, the curse was used to quickly slay opponents during a duel. In 1707, the Wizards' Council was restructured into the Ministry of Magic, which allowed for more strict restrictions on certain types of magic.
Originally Answered: In the Goblet of Fire book, the Avada Kedavra is described as unblockable. However, in the Deathly Hallows movie, Hermione blocks an Avada Kedavra curse aimed at her.
Partly because he's a reasonable person, and doesn't aim to kill. Also, he may have not been physically able to do so. [ professor moody said that the most they could do to him was give him a nosebleed] and, voldemort has the horcruxes, so he wouldn't have been able even if he could produce an avada kedavra curse.
It did backfire on Voldemort but just not the degree it did the first time. It failed to destroy his body because it killed the piece of hit soul that was in Harry forming the horcrux but it did knock him off his feet and actually rendered him senseless.
The author explicitly states that both women were fighting to kill, despite Molly refraining from casting the Unforgivable curse Avada Kedavra. The result of the duel actually comes about as a result of nothing more than spectacular accuracy on Weasley's part.
The book and the films diverged. In the book he is not hit with the killing curse. I believe in the movie he is. In the book, the curse that hits Sirius is not identified (although it is rumoured to be Stupefy because of the red light), and him being knocked through the Veil is what causes his death.
In the film, Bellatrix casts a blue spell at Ginny Weasley instead of a Killing Curse, who deflects it using a Shield Charm. In the book she just avoids it.
There is likely a good reason that the Sectumsempra is not an unforgivable curse. It's mostly because Sectumsempra is Snape's personal curse that he created. It is not a widely known or used spell, and it is one that he kept secret — which means it can't be added to the list since no one really knows about it.
