At this point, she believed the Dark Lord did not have powers this boy had. She wanted to see Draco before anyone could kill him for his affiliation with the Dark Lord. Whether or not Harry was alive the answer was always going to be the same so that she could quickly see Draco.
Ever. So there's only one thing to do: protect her child. She had to ask Harry if Draco's still alive. There was possibility that Harry might lie to her, that Draco did die; but like any parent would, she held on to that hope.
Not knowing whether Draco was alive or dead, Narcissa chose to lie to the Dark Lord rather than risk losing her son. When Voldemort asked her to check if Harry was dead and she realised he was, in fact, still breathing, Narcissa seized her opportunity.
Would they still have won the war if she had said Harry was alive? Harry could still defeat Voldemort because Voldemort didn't know that the elder wand belonged to Harry, so Voldemort would still be killed.
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.
Draco Malfoy's mother Narcissa was cold, cunning and devoted to the Dark Lord. But she was also a mother, which meant she was willing to risk everything to make sure her son was safe. When Harry survived Voldemort's Killing Curse for the second time, Narcissa pretended he was dead so she could get to Draco.
Harry tried to use this spell himself. The first time was against Bellatrix after she had killed Sirius. His attempt was unsuccessful because, as Bellatrix mockingly explained: 'You need to really want to cause pain – to enjoy it – righteous anger won't hurt me for long…'
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.
Secondly, she only cared about her family. She did not really care whether or not Harry was alive. At this point, she believed the Dark Lord did not have powers this boy had. She wanted to see Draco before anyone could kill him for his affiliation with the Dark Lord.
Voldemort was scared it had gone wrong and was nervous to check. It was only when Narcissa checked that his arrogance returned. Only then he made up lies about Harry running despite all DE and Hagrid knowing that wasn't true.
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.
Lucius Malfoy may be one of the Dark Lord Voldemort's Death Eaters, but that doesn't have to mean he's a bad father or that he was cruel and had hurt/abused his wife, Narcissa Black Malfoy, and son, Draco Malfoy.
Draco was torn between loyalty to his family, fear of Voldemort and worry for his former classmates. But Draco could not just flit from one position to another in one fell swoop – and instead of denying it was Harry completely, settled for a passive, 'I don't know. '
Narcissa was taught the philosophy of blood purity from a young age and grew up prejudiced in favor of pure-bloods. Thus, like her sister Bellatrix, she cut off contact with her sister Andromeda after she was disowned and burned off the Black family tree for marrying Muggle-born wizard Ted Tonks.
This nuance was lost on Lord Voldemort, who wrongly assumed Severus Snape held the Elder Wand because he was Dumbledore's killer, when in reality Draco had disarmed Dumbledore before Snape arrived on the scene, making Malfoy the wand's true new owner.
Having rendered unknown, shady, (and almost certainly magical) services to King William I, Malfoy was given a prime piece of land in Wiltshire, seized from local landowners, upon which his descendants have lived for ten consecutive centuries.
Sorted into Slytherin House, she met her future husband, Lucius Malfoy, whilst at Hogwarts. It is possible that Narcissa met Severus Snape and other future Death Eaters at Hogwarts, thanks in no small part to Lucius, who has been friends with them ever since.
She checked his body, and felt the beating of his heart. Hands, softer than he had been expecting, touched Harry's face, pulled back an eyelid, crept beneath his shirt, down to his chest, and felt his heart. He could hear the woman's fast breathing, her long hair tickled his face.
Snape agreed to make the Unbreakable Vow because he knew he'd keep it. He was careful with his words on that and that's where he kept his options open - If Draco would be unsuccessful in killing Dumbledore (as Nacrissa feared), then Snape knew he'd have to fall back on his promise to Dumbledore to kill him.
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.
Her sacrifice gave Harry the power of love, a protection spell sealed with the blood spilled by her death.
Neville's role in the prophecy in Order of the Phoenix is frequently referred to in a hypothetical scenario where Neville was the Chosen One rather than Harry. It is often suggested that Voldemort chose Harry over Neville because of Harry's half-blood status.
And the third, the Killing Curse, is named by Hermione; Moody mentions that it can't be blocked, and only one person is known to have ever survived it: Harry Potter. Harry makes use of two of the Unforgivable Curses in the books.
He did not love anyone, and did not care to be loved. He felt nothing for his family, and only wanted his friends in school to rally around him because he wanted to hold power over them. Bellatrix Lestrange was obviously in love with him and worshiped him, but he only cared for her servitude, not her.
But when Ron and Hermione are about to die by Nagini, Ron casts the killing curse as a last resort and it simply rebounds off Nagini as it was nothing.
