The main reason is that Lucius failed to retrieve the prophecy from the Ministry of Magic, put that on top of all the other times Lucius failed, and it leads to him losing any clout he once carried within the
Lucius eventually became a Death Eater, one of the followers of Lord Voldemort, and even one of the most trusted servants, but abandoned that side after the Dark Lord's first fall in 1981. Lucius claimed he had been bewitched by Voldemort through the Imperius Curse and had not meant to serve him.
Also they were highly unsure if their wand worked according to Voldemort's wishes and they would have to face huge repercussions if it failed to do so. Hence , Lucius Malfoy was scared to give away his wand to The Dark Lord.
Wands are extremely personal items for a wizard, almost as much a part of themselves as any real body part. Without it they are defenseless. Giving up their wand would be like declawing a cat, leaving it defenseless.
Because he lost the favor of Voldemort who held infinite more power and control over everything including his family and most importantly his dear son who was seemingly sent on a suicide mission due to Lucius' failures.
Isaacs brings up Lucius' disheveled appearance in Deathly Hallows, raising the possibility that the Malfoy patriarch had begun drinking too much. The way Isaacs saw it, Lucius was in a no-win situation.
The Malfoys are able to avoid serving time in Azkaban, as they provide evidence that helps the Ministry track down the Death Eaters who had fled after the war. It is also probable that, since Narcissa's lie to Voldemort saved Harry's life, the family is pardoned for their crimes.
In the movie, yes, Lucius Malfoy did start to say the incantation for the Killing Curse before he got stopped by Dobby. However, Jason Isaacs, the actor playing him, stated in an interview that he just said the first spell that came into his head, which happened to be Avada Kedavra.
Charity Burbage floats helplessly above a dinner table, as if paralysed. She begs Snape to help her. Voldemort point his wand at her, and a green light erupts out of its end. The light hits Charity, and she falls down on to the table dead, her eyes open and her face splattered with droplets of blood.
The plain answer is no.
Narcissa's greatest moment, however, was when she chose to betray Voldemort in Harry Potter and the Deathly Hallows. Not knowing whether Draco was alive or dead, Narcissa chose to lie to the Dark Lord rather than risk losing her son.
The Malfoys didn't go to Azkaban mainly because at the end of the day, they put their family over Voldemort.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
Draco's refusal to reveal Harry's identity to Bellatrix was not because he liked him. It was because he believed that Harry was the only chance they had at defeating Voldemort. At first, Draco admired and revered Voldemort until he threatened his family's safety.
Voldemort hugged Draco as an improvisation and it wasn't planned. Even Tom Felton (Draco Malfoy) was caught unaware which increased the effect. In Harry Potter style, it was like a welcome for Draco, but as Voldemort had never known love, he didn't know how to hug him very well. Thats why they had the awkward hug.
Reddit user @u/HimuraKenshin states that for Voldemort, taking Lucius' wand is not just about obtaining a new weapon easily. It's also about punishing the Malfoy family — specifically Lucius. “Lucius kept failing him,” and therefore, taking his wand was also a way of humiliating him and exerting his control on him.
Nagini, Voldemort's snake, then eats Professor Burbage's dead body. A story about her "resignation" from Hogwarts appears in the Prophet, but members of the Order of the Phoenix discount it, as they are unable to locate her anywhere after that.
It is revealed that The Order of the Phoenix was betrayed by Kreacher, Sirius Black's house elf, when Sirius, in a fit of anger, gave Kreacher an order that permitted him to speak to Sirius' cousin, Narcissa Malfoy.
RON WEASLEY- BETRAYED HARRY.
In order to conjure the avada kedavra curse, you have to want to kill your victim. We all know that Voldemort could easily kill a child without an ounce of remorse... but not Snape. Snape didn't want to kill Dumbledore, and this was why the spell was blue instead of the usual green.
Though Harry encountered many opportunities that deemed Avada Kedavra necessary, it remains as one of the Unforgivable Curses Harry Potter never cast. For one, he viewed the spell as an immoral practice commonly used by users of the Dark Arts.
Quirrell didn't use the Killing Curse on Harry, because Voldemort said “use the boy” to get the Sorcerer's stone from the Mirror of Erised. If Quirrell had killed Harry right away, he would have lost the chance to get the stone.
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.
When Lucius turns on Voldemort due to the reveal of his Horcruxes, Narcissa divorces him, taking 75% of Malfoy's wealth with her.
That's not a joke, he actually doesn't work. Rowling shared on Pottermore, “Independently wealthy, without any need to work, Draco inhabits Malfoy Manor with his wife and son.” He lives off of inheritance money!, so the lucky man can dedicate his life to hobbies without the stress of making money.
