Every Harry Potter Character Who Uses the Unforgivable Curse
Several characters (including Harry Potter himself) cast unforgivable curses throughout the film, including the horrific killing spell.

The Unforgivable Curses in the Harry Potter series are a series of powerful spells that are forbidden in the wizarding world - but that hasn't stopped several important characters from using them throughout the course of the story. The most famous of the Unforgivable Curses is Avada Kedavra, the killing spell that caused Harry Potter's famous scar - but there are two other lesser-known spells that Ministry of Magic officials consider too dangerous, Not suitable for general use. These include the Imperius Curse and Cruciatus Curse, responsible for mind control and excruciating pain respectively. Although inherently unforgivable, even some of Harry Potter's closest friends and allies sometimes use these curses.
Although Voldemort and Grindelwald are among the most dangerous wizards in the series, they are not the only ones immoral enough to cast these curses on others. Several characters are known to have used curses in the past, and many characters are actually seen using them throughout the film. The power of these curses, especially the Avada Kedavra, is evident from the beginning of the series - many characters are amazed that Harry was able to survive the Killing Curse at Voldemort's hands on the day his parents died, especially Because no one else has done it, proving how dangerous they are.
Lord Voldemort (All 3 Curses)

Voldemort uses the Killing Curse more than any other villain in the series - almost every spell cast from his wand has that familiar green haze. He uses curses completely indiscriminately, killing anyone (including Harry's parents) who gets in his way. He was often seen slaughtering Muggles with the Killing Curse, including his own parents. Voldemort dropped the name Tom Riddle at an early age, but his traumatic past still has a huge impact on his twisted worldview. In the end, it was Voldemort's reliance on the Killing Curse that led to his own death at the Battle of Hogwarts.
But it's not just the deadly Killing Curse that Voldemort uses so often in the movies - he's also been known to use the Cruciatus Curse on several occasions. He was first seen torturing Harry in Little Hangleton graveyard after his resurrection in Goblet of Fire, but it was revealed that he had previously treated fellow Death Eaters such as Peter Pettigrew and Avery II used curse. During the battle at Little Hangleton, Voldemort casts the Imperius Curse on Harry Attempts were made to make him abide by the dueling rules, but he eventually managed to overcome the spell's power.
Draco Malfoy (Cruciatus and Imperius Curses)

Lucius Malfoy, played by Jason Isaacs, is known for his brutal moments in the Harry Potter series, and while his son Draco may not be as powerful, he is still familiar with various Forbidden curse. He had never seen the Killing Curse used, but under Voldemort's strict orders, he used two others. Draco used the Cruciatus Curse on fellow Death Eaters Thorfin Roll and Antonin Dolohov as punishment for allowing Harry to flee Tottenham Court Road, and used the Imperius Curse to spy on Deng for Voldemort. Bullido smuggles a cursed necklace to Hogwarts.
While using these curses is inexcusable, it's important to note that Draco never used them for his own benefit. There was always pressure from Voldemort to force Draco to commit a crime. Dumbledore was one of the most powerful professors at Hogwarts, and Voldemort knew that only a sacrificial Death Eater like Draco could be used to spy on him. Draco has had a serious journey The last few films, while his redemption arc has been problematic, it makes sense that he would want to seek forgiveness for his crimes. He's not like his father, it just took him a while to realize it.
Severus Snape (The Killing Curse)

Snape's true allegiance has always been a mystery, and despite the several crimes he committed during his tenure as a Death Eater, there was one man who trusted him no matter what - Albus Dumbledore. The two were very close, and while they admitted their differences, luckily their combined strength was enough to convince Voldemort that Snape was his ally. However, in order for Snape to truly gain the Dark Lord's trust, he had to use the Unforgivable Curse. Although Snape eventually became Slytherin's greatest hero, he achieved this status by murdering Dumbledore with the Killing Curse.
While it is easy to hate Snape for killing Dumbledore at the top of the Astronomy Tower, it is important to understand that Dumbledore fully approves of his actions, even endorses them. The heroes need a spy in Voldemort's ranks, and Snape is the only one who can. Finally, Snape's infiltration The Death Eaters that led to Voldemort's eventual demise, so his actions clearly worked. This is the only confirmed case of Snape using the curse, and while many consider it "unforgivable", it's easy to understand and justify his use of it that night.
Barty Crouch Jr. (All 3 Curses)

Barty Crouch Jr. caused a lot of trouble for putting Harry's name in the Goblet of Fire, but it was far from his worst crime. For a long time, Barty Crouch Jr. was probably Voldemort's most trusted and loyal follower. He's one of the few Death Eaters who believes in the Dark Lord's cause, rather than simply acting out of fear and self-preservation. He enjoys torturing Muggles and hurting those who stand in his way, as evidenced by his excessive use of the Unforgivable Curse. He cast all three curses while impersonating Mad-Eye Moody at Hogwarts, and used the Imperius Curse to maintain his disguise.
Barty Crouch Jr. was not a very important role in the grand scheme of things, but his appearance in the Goblet of Fire immediately cemented his status as one of Voldemort's most fearsome and dangerous followers. david tennant improv barty crouch jr is It's popular and really gives the character an edge of unpredictability that matches his mercurial personality. He treats the Unforgivable Curses like any other spell, and while there aren't many instances of him using them, he never shows any restraint. He was actually the first character to introduce the Unforgivable Curses, so he was always connected to them in some way.
Bellatrix Lestrange (The Cruciatus Curse)

Another unwavering and loyal follower of Voldemort, Bellatrix Lestrange was the most unhinged and unpredictable of them all. Many of Bellatrix's scenes are also improvised, giving her an equally surprising edge to match her personality. Although she's never killed anyone with Avada Kedavra, she doesn't hesitate to cast Cruciatus when she needs information. She's known to have used the spell on both Neville Longbottom and Hermione Granger as a method of torture and punishment - and she may have been involved in torturing Frank and Alice Longbottom many years ago as well . Her history with the Imperius Curse is mostly unknown.
Bellatrix's disregard for the rules of the Unforgivable Curse was typical of Voldemort's closest followers and immediately made her a force to be reckoned with. voldemort is older The movies suggest that he may be more familiar with these curses than his followers, but there's no doubt Bellatrix knows how to use them effectively. She has no remorse for her victims, reveling in the pain her magic can inflict. The Unforgivable Curse is the best way to judge the morality of a character in the Harry Potter series, and like most other Death Eaters, Bellatrix has proven beyond doubt that she has been completely beyond redemption.
Harry Potter (Cruciatus & Imperius Curses)

Harry Potter is definitely not the first person to think of when thinking about the Unforgivable Curses, but he actually practiced two of the three. Although he never cast the Killing Curse (though he was all too familiar with it), Harry used two other Unforgivable Curses in the process of bringing down Voldemort. He cast Imperio on Bogrod and Travers when he broke into Bellatrix Lestrange's Gringotts vault in Deathly Hallows, and once on Amycus Carroll, Bellatrix Lestrange, and Severus Snape using (or attempting to use) a corona drill. Harry has always fought a good fight, but that doesn't mean he's always strictly following the rules.
Although most authority figures in Harry's life taught him that the Unforgivable Curse should never When used, drastic measures are sometimes required. While his use of the Cruciatus Curse is hard to justify (as they are mostly motivated by anger), his use of the Imperius Curse was necessary to retrieve the Hufflepuff Cup from the Gringotts vault. Without destroying that Horcrux, Harry and his friends would never have been able to defeat Voldemort at the Battle of Hogwarts without risking his return in the future.
