We can say that Narcissa is a loving woman towards the persons she likes and not as supremacist as her sister, husband or son, but having been raised in hatred of Muggles, she inherited this philosophy. A stern advocate of Pure-Blood supremacy, Narcissa prided herself with her family's blood status and was highly condescending towards Muggle-Borns, Half-Bloods, and Blood Traitors, but in less of an open and derisive way like her husband, son, even her older-sister Bellatrix. Lucius and Narcissa's bigoted nature clearly affected their son Draco as well, as he would come to be an arrogant, spiteful, and racist bully at school himself. Despite their superficial good nature, many people, including the Weasleys and Harry Potter were able to see the Malfoys for how scheming they really was. At the first fall of Voldemort, Narcissa and her family claimed to have been under the influence of the Empire spell and they were exonerated. Narcissa was never really faithful to Voldemort and therefore never tried to find him, like her husband. For her unpleasant personality, one of Narcissa’s redeeming qualities was that she genuinely loved her family and wanted to keep them safe from the master of her husband. After being forced to use Malfoy Manor as a hideout for the Death Eaters and, more importantly, when Draco was tasked with the impossible mission of killing Dumbledore, Narcissa’s priorities slowly pivoted from serving Lord Voldemort to protecting her family however she could. She also made an Unbreakable Vow with Severus Snape for he swears to protect Draco until he’s done his task. However, Narcissa never believed that Draco could accomplish this mission and worried about her son to the point of crying. While raised with bigoted ideologies and superficially believing in them, upon facing the cruel reality of enforcing such beliefs, as well as realizing that Voldemort's motivations are entirely self-interested, she finally understood the folly of such hatred. She didn't openly rebel due to fear for the safety of her son, but neither was she a loyal follower anymore.Narcissa also lied to Voldemort when he asked for confirmation of Harry's death in the duel prior to the Battle of Hogwarts, thus becoming an ally for Harry upon confirmation by Harry that her son was still alive. Ultimately, although seemingly approving the ideals of the Death Eaters, Narcissa was only following her husband, but never caring whether Voldemort wins or not. As such, she didn't participate in the final Battle of Hogwarts, prioritizing Draco's safety; it is heavily implied that she holds significant disdain towards Lucius for dragging her and their son into such a hateful, dangerous world.
