Why Did Snape Make the Unbreakable Vow?

Snape was a double agent who was loyal to both Dumbledore and Voldemort, and his true motivations were often unclear. One of the most intriguing aspects of Snape’s character is his decision to make an Unbreakable Vow with Narcissa Malfoy to protect her son, Draco.

The Unbreakable Vow is a magical oath that binds the person who makes it to a specific task or promise. If they fail to fulfill the vow, they will suffer severe consequences, including death.

Snape’s decision to make an Unbreakable Vow with Narcissa has puzzled many fans of the series, and there are several theories about why he did it.

One theory is that Snape made the vow to keep his cover as a Death Eater. By making the vow, he was able to convince Narcissa and Bellatrix that he was truly loyal to their cause and that he would do everything in his power to protect Draco.

This theory is supported by the fact that Snape was able to maintain his cover until the end of the series, and that he was able to provide valuable information to Dumbledore about Voldemort’s plans.

What is the Unbreakable Vow?

The Unbreakable Vow is a magical contract that is made between two parties, usually with a third party present to act as a witness. The vow is unbreakable, meaning that if the person who made the vow fails to fulfill their promise, they will die.

The vow is usually made with a specific purpose in mind, and the consequences of breaking it can be severe. The vow is a powerful tool, but it is not without its risks.

How Does It Work?

The Unbreakable Vow is created by the parties involved holding hands while a third party casts the spell that binds the vow. The spell creates a magical bond between the parties, and if the vow is broken, the bond is broken, and the person who broke the vow dies. The spell is incredibly powerful, and it is not something that should be taken lightly. The Unbreakable Vow is not a curse, but it is a magical contract that can have serious consequences if it is broken.

It is important to note that the Unbreakable Vow is not a common spell, and it is not something that can be used lightly. It is a powerful tool that should only be used in extreme circumstances, and it should only be used by those who fully understand the risks involved.

The Unbreakable Vow is not something to be taken lightly, and it is not something that should be used for personal gain.

Snape’s Motivations

It is believed that Snape made the Unbreakable Vow with Narcissa Malfoy to protect Draco because Dumbledore had ordered him to do so. Snape knew that Draco was in danger and that he would be unable to protect him without making a serious commitment. Snape’s loyalty to Dumbledore was the driving force behind his decision to make the Unbreakable Vow.

Snape’s Love for Lily Potter

Snape’s love for Lily Potter was one of the most significant motivators in his life. He was deeply in love with her, and her death had a profound impact on him. Snape’s love for Lily was so strong that he was willing to do anything to protect her son, Harry Potter, even if it meant putting his own life in danger.

Snape’s love for Lily was also the reason why he ultimately turned against Voldemort. He could not bear to see the woman he loved and her family suffer at the hands of the Dark Lord. Snape’s love for Lily was a powerful force that guided his actions throughout his life.

Snape’s Fear of Failure

Snape was a complex character with many different motivations. One of the most significant was his fear of failure. Snape was afraid of failing Dumbledore, failing Lily, and failing himself. He was constantly striving to prove himself and to live up to the expectations of those around him.

Snape’s fear of failure was evident in his decision to make the Unbreakable Vow with Narcissa Malfoy. He knew that if he failed to protect Draco, he would be putting himself and his loved ones in danger. Snape was willing to make the Unbreakable Vow because he could not bear the thought of failing those he cared about.

The Consequences of Snape’s Vow

Making an Unbreakable Vow is not something to be taken lightly. The consequences of breaking such a vow are dire, as shown when Bellatrix Lestrange was killed for breaking her vow to Narcissa Malfoy. For Snape, the risks involved in making the vow were significant.

Not only did he risk his own life, but he also put the lives of those he cared about in danger. If he failed to fulfill his vow, he would have been killed, and if he succeeded, he would have had to betray his loyalty to Dumbledore and the Order of the Phoenix.

The Unbreakable Vow also had a significant impact on Snape’s relationships with both Narcissa Malfoy and Bellatrix Lestrange. By making the vow, Snape demonstrated his loyalty to Narcissa and her family, which ultimately led to him killing Dumbledore to spare Draco Malfoy from having to do it himself.

However, his actions also strained his relationship with Bellatrix, who never trusted him and saw his vow as a betrayal of the Dark Lord.

Furthermore, Snape’s vow also had an impact on his relationship with Dumbledore. By agreeing to kill him, Snape demonstrated his willingness to do whatever was necessary to protect Draco and maintain his cover as a double agent. However, this act also put a strain on his relationship with Dumbledore, who had grown to trust him over the years.


Snape’s decision to make the Unbreakable Vow was a complex one, driven by a combination of his loyalty to Dumbledore, his desire to protect Draco, and his own personal motivations. While the exact reasons for his decision may never be fully known, it is clear that Snape was willing to take great risks and make great sacrifices in order to achieve his goals.

One thing that is certain is that Snape’s actions had a profound impact on the course of the Harry Potter series. His role as a double agent and his ultimate sacrifice played a crucial role in the defeat of Voldemort and the eventual restoration of peace to the wizarding world.

Despite his controversial and often divisive character, Snape remains one of the most fascinating and complex figures in the Harry Potter universe. His decision to make the Unbreakable Vow is just one example of the many layers that make up this enigmatic character, and it serves as a reminder of the many sacrifices that were made in the fight against darkness and evil.
