Why Didn't Voldemort Use Snape's Body to Gain Access to the Philosophers' Stone?

In Harry Potter, we don’t get many details regarding Voldemort’s attempts to use Snape’s body. However, there are several compelling reasons why such a plan probably wouldn’t have materialized.

Possession and Voldemort's Track Record

The story showcases several instances of possession by Voldemort, and each one provides insights into what might have worked and what didn’t.

Four Examples of Possession

Quirrell: Voluntary possession that worked well while it lasted. Horcrux-diary: Operated on its own and had imperfect control. Nagini: The snake was non-human, so its effect is still unclear. Harry Potter: Voldemort attempted to possess him but failed.

Each of these examples reveals that possession is problematic if the target isn’t willing. The spirit form Voldemort likely wouldn’t risk an involuntary possession that failed.

Severus Snape's Uncertainty

Severus Snape’s character development leads to ambiguity about his loyalties. While he had reformed and was hesitant about Voldemort’s plans, it is unclear whether he truly supported Dumbledore or if his allegiance was solely to protect the mission.

From Voldemort's perspective, it was challenging to discern Severus’ true intentions. This uncertainty might have made Voldemort hesitant to swap hosts. Why risk switching to a possible traitor when Quirrell was effective?

Quirrell's Risks and Competence

Quirrell, despite his suspicions, played a significant role in accessing the Philosophers' Stone. His willingness to break into Gringotts to steal the stone indicates a level of competence that cannot be overlooked.

While Quirrell’s actions might suggest he was willing to undertake dangerous tasks, his exposure to Voldemort’s wrath might have made the situation worse. Voldemort’s possession of Quirrell was so weak that it’s questionable how much stronger a grip he would have had with Snape.

Conclusion: Uncertain Gains and High Risks

Given the track record of possession and the uncertainty about Snape’s true motives, it appears that Voldemort might have been wary of switching hosts. While there could have been some potential benefits from using Snape, the risks of failure and exposure would have been too high.

In conclusion, while the idea of Voldemort using Snape’s body is intriguing, the uncertainties and risks involved likely outweighed the potential gains, rendering this strategy impractical.
