Bellatrix despises Sirius so deeply, there's a reason he was kicked out of Grimmauld Place (and his family). He refused to support the ancient House of Black's prejudice towards Muggles, Muggle-borns, and Half-bloods. He was a Gryffindor, breaking the Black's family tradition of being Slytherin.
Of course Bellatrix wanted to kill Sirius. She's a crazed psychopath who enjoys killing, and Sirius openly defied everything Bellatrix believed was right.
Originally Answered: Did Bellatrix feel sorry for killing Sirius? Bellatrix isn't sad about killing Sirius. She taunts Harry about it. Far from showing remorse for killing Sirius, she next stalks her niece, Nymphadora Tonks.
Upon the dais is a stone archway, covered with a tattered black veil. Sirius is hit by Bellatrix's curse, and his stunned body arcs into the air and floats through the archway, disappearing behind the veil.
Bellatrix won the fair fight with Sirius in Order of the Phoenix, though it was circumstances that killed him, not his cousin—Sirius was hit with a stunning spell, not Avada Kedavra, and died by falling through the veil. This does not make it unfair, of course, but it does seem to have been cut short.
Bellatrix only cast the Killing Curse on Sirius in the movie, but in the book she cast an unknown spell that pushed him into the Veil, so Sirius did not canonically die by the Killing Curse.
Originally Answered: What made Bellatrix Lestrange so cruel and sadist? I suspect that, as usual, it was a mixture of both nature and nurture. Bellatrix was born in the Black family, which had a history of instability and an insular approach to the outside.
It is assumed Bellatrix was at least initially drawn to Lord Voldemort because they both believe in an ideology that favors pure-blood wizards and witches over other members of the community. This elitism, shared by the Malfoy and Lestrange clans, was instilled in Bellatrix since childhood.
Bellatrix was one of Voldemort's cruelest Death Eaters, always eager to inflict the Cruciatus Curse on enemies. Harry Potter noted that she was as "mad as her master". Probably because of these similarities, Bellatrix was slavishly devoted to Lord Voldemort and was ready to do whatever was necessary for his cause.
Who is Delphini raised by? After the deaths of her parents, Voldemort and Bellatrix Lestrange, Delphini is raised by Euphemia Rowle, who was not fond of her and allegedly only took her because she was offered a substantial amount of gold.
During the final battle, Bellatrix was the last Death Eater standing. She was eventually killed in a duel by Molly Weasley after her attempted murder of Ginny Weasley. Before her death, Bellatrix secretly gave birth to an illegitimate daughter named Delphini, whom she conceived with her beloved master, Lord Voldemort.
Her disregard for human life and her pleasure in others' pain made her a deadly force. Bellatrix's devotion to Voldemort also means that she would have done anything to please him — no matter the cost. However, what fans most despise her for is the murder of her cousin, the beloved Sirius Black.
Given that Snape and Sirius have been given birth years of 1960, this would make both of them only about 5 years younger than Andromeda and likely 6 or more than Bellatrix.
In an interview with Entertainment Weekly, Helena Bonham Carter spoke about Bellatrix Lestrange's Pure Evil status, noting that she is a very sick sadist and racist with problems who, despite serving so long in prison, most likely already was troubled beforehand.
Sirius is recognized for his unwavering loyalty and love for his friends and Harry. He loves Harry, and his affection is generous. He was devoted to James, Lily, Remus, Harry, Ron, Hermione, Gryffindor, and the Order.
At the end of the First Wizarding War, Bellatrix, her husband, Rodolphus Lestrange, his brother Rabastan, and Barty Crouch Jr. tortured Aurors Alice and Frank Longbottom to the point of insanity searching for information on Lord Voldemort after his first downfall.
In the play "Harry Potter and the Cursed Child," which has become part of "Harry Potter" canon, it was revealed that Bellatrix conceived a child with none other than Lord Voldemort.
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.
History. Bellatrix held this knife to Hermione Granger's throat in the spring of 1998 in Malfoy Manor, after having tortured Hermione into unconsciousness, prompting Harry Potter and Ron Weasley to rush to her rescue once Dobby the house-elf freed them from the dungeons below.
The prolonged misery of being exposed to dementors kept the prisoners locked within their own minds, so Sirius lost the ability to transform. However, Sirius explained that the knowledge of his innocence kept him sane in a way most of Azkaban's prisoners were not.
Sirius states that unlike most other Azkaban prisoners (who often became insane during their terms of imprisonment), he was able to keep his sanity because he knew he was innocent, and also used his Animagus form to ward off the Dementors, who are unable to perceive unsophisticated canine minds.
Black was able to maintain his sanity due to his knowledge of his innocence, a non-happy thought that the Dementors could not take. It was only this that allowed him to maintain his powers to transform, and what made the escape possible.
Of course, circumstances play an important role, as Bellatrix Lestrange manages to kill other powerful wizards such as Sirius Black through her occasionally unfair strategies, but in a proper one-on-one duel, Professor McGonagall would win.
