Based on the provided information, it was not Draco Malfoy who lied about Harry being dead, but rather his mother, Narcissa Malfoy. She did so to confirm the safety of her son and, upon receiving confirmation, chose to protect Harry, which ultimately aided in Voldemort's downfall.
While the question asks about Draco Malfoy, the reference explicitly states that "she plainly lied that Harry Potter was 'dead'". In the context of the events described, 'she' refers to Narcissa Malfoy.
Understanding Narcissa Malfoy's Decision
Narcissa Malfoy's decision to lie to Lord Voldemort about Harry Potter's status during the Battle of Hogwarts was a pivotal moment. Her motivation was rooted in her maternal love for her son, Draco.
- Primary Goal: Narcissa needed to know if Draco was alive and safe within Hogwarts Castle. Voldemort was demanding confirmation of Harry's death, and Narcissa saw an opportunity.
- The Deal: She quietly questioned Harry (who was feigning death) about Draco's status. Only upon Harry confirming that Draco was alive and safe within the castle did Narcissa make her choice.
- The Lie: Despite knowing Harry was alive, she told Voldemort that Harry was dead.
Why the Lie Was Crucial
According to the reference, this lie had significant consequences:
- Harry's Survival: It allowed Harry to be carried back to the castle among the "dead," giving him the element of surprise and a chance to plan his next move.
- Voldemort's Final Defeat: Harry's survival was essential for the final confrontation that led to Voldemort's demise.
- Mother's Love Protection (Indirect): The reference highlights that this action ensured Harry was "again protected by a mother's love, although indirectly." Just as Lily Potter's sacrifice protected Harry as a child, Narcissa's choice, driven by her love for her own son, indirectly provided a form of protection for Harry at this critical juncture.
Summary of Reasons:
| Reason | Details | Impact on Harry |
|---|---|---|
| Confirm Draco's Safety | Her immediate priority was ensuring her son was alive and out of danger. | Indirect (Led to her lying) |
| Secure Son's Life | Lying to Voldemort could have put her at risk, but her son's safety was paramount. | Indirect (Led to her lying) |
| Indirect Protection | Her lie allowed Harry to survive and continue the fight against Voldemort. | Direct |
| Contribute to Voldemort's Downfall | By keeping Harry alive, she inadvertently played a role in the Dark Lord's eventual defeat. | Direct |
In essence, Narcissa's love for her son outweighed her fear of Voldemort. Her lie was a calculated risk taken out of desperation to protect her family, which serendipitously aligned with the need to protect Harry Potter.
