Snape was serving as a triple agent for Voldy, Dumbledore, and back to Voldy. He "went back to" being a death eater when Voldy returned to power even though he was not devoted.
When questioned by Bellatrix about his loyalties, Snape says he has been working for Voldemort ever since Voldemort's return, and explains his actions in the previous books in that light. He points out that gaining Dumbledore's trust and protection has kept him out of Azkaban and free to operate on Voldemort's behalf.
Distrusted for his past as a Death Eater by those on Albus Dumbledore's side, and hated by other Death Eaters for living as Dumbledore's stooge for ten years, Snape continued living on to complete Dumbledore's plan to protect Harry and defeat Voldemort.
His negative experiences with his muggle father and neglectful witch mother contributed to his decision to join the Death Eaters. Snape's strained relationship with Lily, who chose James and allowed him and his clique to bully Snape, further pushed him towards the Death Eaters.
Snape's obsession with the Dark Arts and lack of emotional support eventually led to him joining Voldemort's ranks. Voldemort ultimately killed Lily, and Snape appeared to stay loyal to his cause. However, this event led to him working as a spy for Dumbledore.

Did Voldemort really regret killing Snape?
Voldemort told Snape he had been a faithful servant, but that he had to regrettably kill him, as he mistakenly believed he was the master of the Elder Wand, as Snape had killed Albus Dumbledore, its former owner the year prior, during the Battle of the Astronomy Tower.
Snape was serving as a triple agent for Voldy, Dumbledore, and back to Voldy. He "went back to" being a death eater when Voldy returned to power even though he was not devoted. He was really giving info to the order.
As much as people romanticize Snape's infatuation with Lily, the fact she did not love him back romantically is ignored. The fact Snape and Lily were only friends, and she only saw it as such, reveals a lot about his refusal to respect her boundaries.
However, there were a select few that had his trust, and whom he treated with respect. This included Bellatrix Lestrange and Severus Snape. No matter what Snape did as a spy, Voldemort never figured out he was not on the Dark Lord's side.
Summary. As a character, Severus Snape was often misunderstood. Many believed he was a villain, and weren't convinced he was actually working for Dumbledore. Snape killed Dumbledore in an effort to protect Draco Malfo and spare him from the emotional trauma of murder.
When Snape heard the prophecy and pleaded with Voldemort to spare Lily's life, he may have inadvertently caused his downfall. While we know Voldemort killed Lily, he did give her a choice. If she stepped aside and allowed him to murder Harry, he would spare her. Lily refused and sacrificed herself to save her son.
In Draco's case, he is angry at Snape for taking his father's revered spot during his disgrace (Death Hallows: the Prince's Tale); he may have thought he set his father up since it was pretty easy to deduce that Snape informed Dumbledore what was happening.
By Harry Potter and the Deathly Hallows, it's a stretch to call Draco a villain anymore. We just watched — or read — him struggle to reconcile his choices and morals in The Half-Blood Prince. He can no longer justify his actions, and is far more aware of the evil he was born and raised into.
Since the first Harry Potter movie, Severus Snape was presented as a villainous figure, but once the final installment was released, viewers learned his intentions were never evil — leading to the endless debate over was Snape good or bad.
McGonagall later learned that Snape was secretly Harry's protector and had killed Dumbledore at Dumbledore's request. McGonagall then made a controversial decision to add Snape's portrait in the Headmaster's Office as a testament to his bravery.
At this point, McGonagall begins to gain the upper hand as it becomes clear he cannot further transfigure or counter her attack, so the only way he avoids it is by taking refuge behind a suit of armour that he forces in front of him.
With the return of his Death Eaters at the end of Book Four, Voldemort declared that Snape had left their ranks forever. Conversely, Dumbledore went on declaring his undying trust in Snape. So Dumbledore was no more wrong than was Voldemort.
J.K. Rowling apparently confirmed that Lily Potter was pregnant again when Voldemort murdered her | Fandom. Thus, in murdering the Potters, save for Harry, Voldemort also killed a younger brother or sister that Harry would ultimately never know before it was even born.
Originally Answered: In the Harry Potter series, why didn't Lily marry Snape? The simple answer: She didn't love him. The more complicated answer: He proved again and again that he wasn't willing to listen to Lily, respect her or her views, or love her in a healthy way.
She was the first person to show him any love, and as they grew into their teenage years he became infatuated with her. Severus Snape and Lily Evans were childhood friends who met when they were young and attended the same Muggle primary school.
In Harry Potter's third year at Hogwarts, his nasty, bullying Potions master, Severus Snape, tells him openly for the first time how much he hated Harry's dead father, James: 'He, too, was exceedingly arrogant… Strutting around the place with his friends and admirers… the resemblance between you is uncanny.
It can also be that he was too cowardlt to do it himself and/or even had felt a sense of regret with killing Snape. The more factual reason is probably because he believed Snape owned the wand, and by owning the wand, the wand would never kill Snape.
Snape's loyalty to Lily is not something that ever really ends; it follows him and informs many of his other alliances for his whole life. When Snape first meets Lily, he is desperate for a friend, for someone to relate to. He finds that in her.
