Quick answer: Severus Snape killed Albus Dumbledore with Avada Kedavra on the Astronomy Tower. The act initially looks like a shocking betrayal. Later, Deathly Hallows reveals that the headmaster had asked Snape to kill him as part of a larger plan.
Who Killed Dumbledore in Harry Potter?
Severus Snape delivers the fatal spell. The killing happens near the end of Harry Potter and the Half-Blood Prince. Harry witnesses the scene while hidden and unable to intervene.
The moment deliberately makes Snape appear loyal to Voldemort. Readers know that Snape has a complicated history with the Death Eaters. His actions on the tower therefore seem to confirm Harry’s worst suspicions.
That interpretation changes after Harry sees Snape’s memories in Deathly Hallows. Those memories reveal an agreement between Snape and the headmaster. They also explain why Snape’s apparent betrayal served a larger purpose.
Why Did Snape Kill Him?
Snape did not murder the headmaster because he suddenly switched sides. The two men had discussed the death before the Astronomy Tower confrontation. Their arrangement became necessary because a powerful curse was already killing the older wizard.
The plan also protected Snape’s position as a spy. Voldemort needed to believe that Snape remained completely loyal to him. Killing one of Voldemort’s greatest enemies gave that deception extraordinary credibility.
There was also a personal cost for Snape. He knew his allies would see him as a murderer afterward. He accepted that reputation because maintaining his cover remained important to the fight against Voldemort.
The Cursed Ring Had Already Sealed His Fate
Albus Dumbledore had previously found Marvolo Gaunt’s ring, which Voldemort had turned into a Horcrux. The ring contained a dangerous curse that spread after he put it on. Snape contained the damage, but he could not remove it.
The curse meant the Hogwarts leader did not have long to live. His death was therefore approaching before Draco completed Voldemort’s assignment. This fact changed the purpose of Snape’s eventual action.
The ring also contained the Resurrection Stone, one of the Deathly Hallows. The stone appealed to the older wizard because of unresolved grief surrounding his family. Touching it ultimately exposed him to Voldemort’s curse.
Why Draco Malfoy Was Ordered to Commit the Murder
Voldemort gave Draco Malfoy the task after Lucius Malfoy fell from favor. The assignment placed enormous pressure on the teenager and his family. Draco spent much of the school year trying to find a way to succeed.
His earlier attempts included a cursed necklace and poisoned mead. Neither attempt reached the intended target, and other people were endangered. The failures showed how dangerous Draco’s mission had become for everyone around him.
Draco finally confronted Dumbledore on the Astronomy Tower after disarming him. Yet he hesitated when the moment to kill arrived. Official Wizarding World material confirms that Draco could not bring himself to deliver the fatal attack.
Why Saving Draco Mattered
The headmaster believed Draco was not naturally a killer. During their tower conversation, he tried to give the teenager another path. He even offered protection for Draco and his family.
Allowing Draco to commit murder would have carried serious moral consequences. The series repeatedly connects deliberate murder with damage to the soul. Preventing that act therefore mattered beyond simply protecting Draco from punishment.
Snape taking over the mission solved several problems at once. Draco avoided becoming the person who cast the fatal curse. Snape also preserved his credibility inside Voldemort’s circle.

The Unbreakable Vow Added Another Layer
Before the school year begins, Narcissa Malfoy asks Snape to protect her son. She fears Voldemort has assigned Draco an impossible mission. Snape agrees to an Unbreakable Vow in Bellatrix Lestrange’s presence.
One part of that vow requires him to finish Draco’s task if the boy cannot complete it. Breaking an Unbreakable Vow carries fatal consequences in the wizarding world. The promise therefore places additional pressure on Snape.
Still, the vow is not the only reason for the killing. The secret arrangement between the two Hogwarts professors is central to the later explanation. The vow and that agreement ultimately point Snape toward the same action.
What Happened on the Astronomy Tower?
Harry and the headmaster return to Hogwarts after a dangerous mission involving one of Voldemort’s Horcruxes. The older wizard is severely weakened during the journey. Events at the school then move quickly toward the tower confrontation.
Draco arrives, disarms him, and explains how Death Eaters entered Hogwarts. He cannot bring himself to finish the assignment. Other Death Eaters soon reach the tower and pressure Draco to act.
Snape then appears and understands what must happen. He casts Avada Kedavra, sending the headmaster falling from the tower. Harry pursues Snape afterward, believing he has witnessed an unforgivable betrayal.
What “Severus, Please” Really Means
One detail becomes especially important after the later revelation. Just before Snape casts the curse, the headmaster addresses him by name and pleads with him. First-time readers can reasonably interpret this as a request for mercy.
The later memories change the meaning of that moment. His words can instead be understood as a reminder to carry out their agreement. Snape must do something he never wanted to do.
That reinterpretation is one reason the scene remains important to the series. The same words carry a different meaning after readers learn the hidden plan. The story uses that change to reshape how we see Snape’s earlier actions.
Was Snape Good or Evil After This?
The death does not erase Snape’s other harmful choices. He could be cruel, resentful, and unfair toward several students. His history also includes willingly joining the Death Eaters before later turning against Voldemort.
At the same time, his work as a double agent required serious personal risk. He continued helping the resistance while Voldemort believed he was a loyal servant. His role is therefore written as morally complicated rather than simple.
The tower scene captures that complexity better than almost any other moment. An action that looks like treachery becomes evidence of a dangerous undercover mission. Readers can still judge his broader character differently once they know the facts.

Did the Plan Affect the Elder Wand?
The Elder Wand adds another complication to the events surrounding the death. Draco disarms the wand’s owner before Snape arrives. This matters because the wand’s allegiance does not simply follow the person who kills it.
Harry eventually understands that Draco became the wand’s master by defeating its previous owner. Harry later defeats Draco and gains its allegiance himself. Voldemort misunderstands this chain of ownership during the final confrontation.
This detail explains why killing Snape does not give Voldemort true mastery of the Elder Wand. He assumes the murderer inherited the wand’s loyalty. The story later shows that assumption was wrong.
Is the Explanation the Same in the Books and Movies?
The core answer remains the same in both versions. Snape casts the fatal curse after Draco fails to complete Voldemort’s assignment. Later revelations establish that the death was arranged beforehand.
The books give more space to the motives and consequences behind the plan. They explore the cursed ring, Snape’s memories, and wand allegiance in greater detail. The films compress some of those explanations for pacing.
Both versions still lead to the same essential understanding. The tower scene is not evidence that Snape secretly betrayed his longtime ally. It is the execution of a painful strategy developed before that night.

Final Takeaway
Severus Snape casts the spell that kills the Hogwarts headmaster, but context changes the scene’s meaning. The act fulfills a secret agreement and keeps Draco from committing murder. It also protects Snape’s dangerous position inside Voldemort’s forces.
That is why the Astronomy Tower sequence works as more than a major character death. Its meaning changes when Harry finally receives Snape’s memories. The apparent betrayal becomes one of the series’ most important hidden plans.
