Later life. Lucius and Draco's crimes were forgiven due to their abandonment of Voldemort and his cause and Narcissa's lie to the Dark Lord that saved Harry Potter's life in the Forbidden Forest in the Battle of Hogwarts. None of them served time in Azkaban.
Because Draco Malfoy was under duress, either he killed Dumbledore or Voldemort killed him and his family, so his attempted murders are not criminally prosecutable. Furthermore, only the golden trio, Snape and Dumbledore know what Draco did, and no one would report him.
Draco might not deserve azkaban, but he still deserves punishment. IMO an ideal, and fitting punishment both in terms of justice, but also just theme, would be for Draco to have his wand snapped/confiscated for years.
Later life. However, as Narcissa betrayed Voldemort and left him, the entire Malfoy family was granted a reprieve and avoided incarceration in Azkaban. Narcissa would eventually become a grandmother to Scorpius Malfoy, the son of Draco and his wife Astoria Greengrass.
In Book 7, he chose to not rat out Harry and his friends' true identities at Malfoy Manor. He didn't want to be a Death Eater, once he realized what being a Death Eater truly meant. He didn't want to be on Voldemort's side, once he came to truly understand what Voldemort stood for.
In his memoir, Felton said that Fiennes improvised Voldemort awkwardly hugging Draco Malfoy. "It gave me goosebumps then, and the memory gives me goosebumps now," Felton wrote.
In fact, Lucius' own support to Voldemort is revealed to come only under some form of duress, which is likely Narcissa's Veela Allure. When Lucius turns on Voldemort due to the reveal of his Horcruxes, Narcissa divorces him, taking 75% of Malfoy's wealth with her.
During this year, Narcissa became pregnant and miscarried. She was distraught and uncertain of what to tell Lucius, as she had not told him of her pregnancy. Shortly thereafter, he brought her out to the Leaky Cauldron to visit with his friends Vettlingar Yaxley and Thorfinn Rowle.
He called her Dromeda, perhaps her own childhood nickname, or perhaps a new one to mark her new family. She was immediately disowned as a blood traitor, and from that day onwards she never saw her sisters again.
Because he and his family defected from the Death Eaters they were pardoned for their crimes after Voldemort's final defeat and did not serve a stint in Azkaban. He and Narcissa later had a grandson, Scorpius Malfoy, after Draco married Astoria Greengrass.
J.K. Rowling says Draco doesn't have a patronus because he never learned the spell but I think it's because he doesn't have any powerful happy memories to use. He has tons of happy memories... He had an amazing childhood. However, she also said Snape was the only Death Eater who could produce a Patronus.
Lucius and Draco's crimes were forgiven due to their abandonment of Voldemort and his cause and Narcissa's lie to the Dark Lord that saved Harry Potter's life in the Forbidden Forest in the Battle of Hogwarts. None of them served time in Azkaban.
The Malfoys are related to the Black family through Narcissa (a first cousin of Sirius Black, Harry's godfather), which makes Draco a nephew of both Bellatrix Lestrange and Andromeda Tonks.
Family. Snape's family background is mostly shown in flashbacks during the course of the last three novels. Snape was born to Eileen Prince, a witch, and Tobias Snape, a Muggle, making him a half-blood (hence the name, "Half-Blood Prince").
Malfoy hated all the attention Harry recieved . Malfoy thought Harry was a dark wizard, he tried to befriend Harry but he refused because of the way Malfoy treated Ron whom he already made friends with. That's why Malfoy hate Harry for turning him down.
She married Rodolphus Lestrange after leaving Hogwarts "because it was expected of her" to marry a pure-blood. However, Rowling stated in an interview that Bellatrix truly loved Voldemort.
Something that people get wrong about Narcissa Malfoy is that she was a Death Eater, when in fact she was never part of Voldemort's inner circle of believers. She certainly affiliated with the Dark Lord's side, but her maternal side won over her evil one when she had to check if Harry was still alive in the Forest.
Narcissa may have been many things; she was cruel and distant and happy to watch her family return to Lord Voldemort's side as he rose again, but she was also self-sacrificing; she loved her son and her husband and she thought nothing of putting herself in danger to protect them.
Why didn't Lucius and Narcissa have more children?
One, the Malfoys simply wanted a single male heir to avoid spreading their inheritance. Since their firstborn was a boy, they didn't have a need for more children. Another was that Narcissa was quite strained by her first pregnancy and didn't want to repeat the experience.
Alyssienna Symphonia Rowena Narcissa "Allie" Malfoy is the second child and only daughter of Lucius and Narcissa Malfoy, and the AquaMagenta twin sister of Draco Malfoy.
Bellatrix was born into the Black family, so it may be obvious to some fans that she got married at some point, given her surname. But not much information is given about her husband, Rodolphus Lestrange, in the book — and he's not a character in the movies — so it's easy to forget the witch was ever married.
None of the Malfoys were subsequently imprisoned in Azkaban because of this defection. Draco then married Astoria Greengrass sometime between 1998-2005, and had a son called Scorpius circa 2006. In 2017, Draco and Astoria were at King's Cross station to see Scorpius off to Hogwarts when Harry Potter saw him again.
It is also probable that, since Narcissa's lie to Voldemort saved Harry's life, the family is pardoned for their crimes. They keep a relatively low profile after that, while continuing to live a leisurely life in the Malfoy Manor.
