Lucius was seen by a myriad of Ministry officials called by Albus Dumbledore to the scene; now with irrefutable evidence pointing to his identity as a
Following his failure to obtain an important prophecy at the end of Order of the Phoenix, Lucius is sent to Azkaban for a while until Voldemort breaks him out, although he doesn't play much of a role in the series going forward.
Dumbledore knew for sure that Lucius Malfoy is a Death Eater. The problem was that Dumbledore didn't have any authority to do something about it on his own and he didn't have enough physical evidence to prove it in front of the Wizengamot.
According to Harry Potter: The Wand Collection (your canon mileage may vary) Lucius did intend to kill Harry using Avada Kedavra prior to Dobby stopping the act... Lucius is a known practitioner of the Dark Arts with his wand, including Unforgivable Curses.
Why? 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 Death Eaters.
He was more jealous of Harry than he let on
Specifically, Draco was jealous of Harry. It was easy to miss because Draco didn't often show his emotions, modelling himself on his cold, confident, calculating father, but J.K. Rowling has confirmed that a lot of his enmity towards Harry stemmed from envy.
While disguised as Moody, Crouch attacks Draco by turning him into a ferret. Initially, this comes across as a gesture of goodwill as “Moody” says he did it because Draco was going to curse Harry behind his back. This sort of small detail in Goblet of Fire hides the twist that Moody is Crouch in disguise.
Who is immune to Avada Kedavra? Phoenixes were semi-protected from the Killing Curse, due to them being immortal. In 1996, Fawkes swallowed one intended for Albus Dumbledore, causing him to burst into flame and die instantly. However, he then was reborn from his ashes.
The plain answer is no. The Killing Curse is illegal, not to mention its use carries the punishment of a life sentence without parole in Azkaban. Someone as shrewd and cunning as Lucius' character, who made sure to get rid of Dark magic items earlier wouldn't have intended to use it on Harry.
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.
Bellatrix Lestrange (née Black) is the first female Death Eater introduced in the books. Aunt of Draco Malfoy and Nymphadora Tonks. She was introduced in Harry Potter and the Order of the Phoenix. She is the most faithful member of Voldemort's inner circle.
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.
Marietta Edgecombe's defection not only betrayed Dumbledore's Army, but ultimately doomed Harry and Cho Chang's relationship.
Lucius's visit
At the end of Chamber of Secrets, we learn that one of his deadly items is Tom Riddle's diary, which he slips into Ginny Weasley's possession during the same trip to Diagon Alley.
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.
It is interesting also to note that Harry does not actually kill Pettigrew, but that Voldemort's gift kills him despite Harry's efforts to save him. Pettigrew's death is a reaction to his own attempt to kill, or at least, disable Harry, coupled with Voldemort's distrust of his own lieutenant.
Lucius Malfoy appeared weak because he was under the constant strain under Lord Voldemort. His son had already failed him in not having enough courage to kill Dumbledore and also, his family's life and his were under constant threat of death as they didn't search for Lord Voldemort when he was not fully functional.
One such unforgivable curse is Avada Kedavra, and yes, the killing spell is in Hogwarts Legacy and you can use it. While we're not advocating the use of the horrible spell, it is powerful in game and will prove handy against tough enemies as it is a one-hit kill curse.
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.
Her sacrifice gave Harry the power of love, a protection spell sealed with the blood spilled by her death.
Avada Kedavra
Topping the list for the most powerful spells in the Harry Potter universe is no other than Avada Kedavra, Voldemort's favorite to instill his will and fear onto others. The spell itself is a play on Abra Kadabra and is easy to cast by just about anyone in the Wizarding World.
The evil Draco Malfoy, Harry's rival, has the biggest owl of all in England, the Eurasian Eagle-Owl. [Eurasian Eagle-Owl call] With sinister orange-red eyes, he makes a perfect pet for a villain [Eurasian Eagle-Owl].
Crouch therefore displayed both an aptitude for magic and a skill with secrecy that nobody else pulled off. His skill even overshadowed Voldemort's, since Dumbledore was on to his Horcrux plan. Most damning of all, when he posed as Mad-Eye Moody, Barty Crouch Jr. was a legitimately good teacher!
Alastor "Mad-Eye" Moody managed to alter the Triwizard Tournament in Harry Potter and the Goblet of Fire as the one who put Harry's name in the Goblet of Fire, but it took a well-orchestrated plan.
