Dumbledore helped Severus Snape but not Sirius Black primarily because Dumbledore believed Sirius was guilty of betraying the Potters, while he saw Snape as having actively contributed to the fight against Voldemort and showing signs of redemption.
Dumbledore's perceptions of the two men were vastly different, shaping his decisions and actions toward each.
Dumbledore's View of Severus Snape
Albus Dumbledore's relationship with Severus Snape was complex, built on a foundation of trust that Snape eventually earned, largely due to his deep, abiding love for Lily Potter.
- Active Contribution Against Voldemort: Dumbledore recognized that Snape, regardless of his initial motivations or the darkness of his past as a Death Eater, actively assisted in the fight against Lord Voldemort. Snape functioned as a double agent, feeding vital information to Dumbledore and the Order of the Phoenix. His actions were instrumental in various stages of the war.
- Steps Towards Redemption: On an emotional level, Dumbledore believed Snape had taken significant, tentative steps towards redemption. Snape's remorse over Lily Potter's death and his subsequent dedication to protecting Harry Potter, at Dumbledore's insistence, demonstrated a profound shift in his allegiance and character. Dumbledore saw this as genuine change, making Snape a valuable, albeit difficult, ally.
- Strategic Asset: Snape's position as a Legilimens and a trusted aide to Voldemort made him an irreplaceable strategic asset. Dumbledore leveraged Snape's unique capabilities to gather intelligence directly from the Death Eaters' inner circle, a feat no one else could accomplish.

Dumbledore's View of Sirius Black
In stark contrast, Dumbledore harbored a strong conviction about Sirius Black's guilt for many years, which prevented him from intervening on Sirius's behalf.
- Presumed Guilt: For twelve years, Dumbledore believed Sirius Black was "as guilty as sin." The prevalent narrative, supported by seemingly irrefutable evidence, was that Sirius had betrayed James and Lily Potter to Lord Voldemort and murdered Peter Pettigrew, along with twelve Muggles. This belief led to Sirius's unjust imprisonment in Azkaban without a trial.
- Lack of Direct Evidence for Innocence: While Dumbledore was known for his wisdom, he did not initially have any concrete evidence to counter the widespread belief in Sirius's treachery. The secret of the Potters' Secret Keeper being Peter Pettigrew was known only to a select few, and Dumbledore was under the impression it was Sirius.
- Later Support, But Too Late: It was only much later, in Harry's third year, after Peter Pettigrew was revealed to be alive and the true betrayer, that Dumbledore fully accepted Sirius's innocence. By this point, Sirius had already endured years in Azkaban, and Dumbledore's subsequent help was aimed at aiding Sirius as a fugitive and later as a member of the Order of the Phoenix, but not at retroactively preventing his initial unjust incarceration.

Key Differences in Dumbledore's Perceptions
The following table summarizes the fundamental differences in how Dumbledore perceived Snape and Sirius, which dictated his actions towards them:
| Aspect | Severus Snape | Sirius Black |
|---|---|---|
| Initial Belief | A former Death Eater, but with a crucial change of heart. | A traitor who betrayed his friends, "guilty as sin." |
| Active Role | An indispensable double agent and spy. | An incarcerated criminal. |
| Emotional State | Showing tentative steps towards redemption due to love for Lily. | Perceived as a cold-blooded killer. |
| Strategic Value | Uniquely positioned to gather intelligence from Voldemort. | None, due to imprisonment. |
| Dumbledore's Action | Offered trust, protection, and a vital role. | Did not intervene for his release for 12 years. |
In essence, Dumbledore acted based on the information and beliefs he held at the time, seeing Snape as a key player in the war against Voldemort and Sirius as a convicted betrayer.
