Snape Tried To Get Voldemort To Spare Lily As soon as Snape discovers that the information he passed on to his beloved Dark Lord led to the woman he loved, he begged his master to spare her life. This is the moment that saved Harry's life, where Lily chose instead to sacrifice herself to protect her infant.
It was Snape that persuaded Voldemort to give Lily a chance to save herself. He also protected Harry during his time at school (however reluctantly). He risked his life constantly as a double agent. He was the one who was in on Dumbledore's plan for Harry.
Snape shares what he heard of the prophecy with Voldemort. Voldemort decides the child must be Harry Potter, not Neville Longbottom. Snape pleads with Voldemort to spare Lily's life, but his pleas are coldly received. Snape goes to Dumbledore to ask Dumbledore to protect for Lily and her family.
He agreed to give Lily a chance to save herself, but he certainly didn't promise to save her life. Voldemort was actually true to his word when he said that he'd give Lily a way out. He gives her several chances to run away and leave Harry.
Voldemort had no idea Snape had loved Lily (he was told the latter desired her in a sexual, non romantic way) until Harry told him, hence the wild denial. The evidence for Snape's continued love, his doe Patronus, was known only to Dumbledore.
The fact that Lily chose James Potter, Harry's father, only fuels Snape's hostility towards Harry. Snape's character has been widely acclaimed by readers and critics. Rowling described him as "a gift of a character" whose story she had known since the first book.
To be fair, James would (and did) willingly die for Lily too. But Snape loved Lily so much that he was willing to die just to avenge her. He would die just for the memory of her.
Snape's obsessive love for Lily fed his equally obsessive hatred for James, and meant he would stop at nothing ' even arranging the murder of her child ' to possess Lily.
As much as people romanticize Snape's infatuation with Lily, the fact that she did not love him back—at least in a romantic fashion—seems to go ignored by many fans of the series. The fact that Lily only ever saw Snape as a friend reveals a lot about his refusal to respect her boundaries.
Voldemort can not comprehend love, and so it destroys him to touch Harry because Lily's love for her son runs through Harry's veins and body. ems Harry burnt Quirrell's face when he touched it.
12. Snape's Last Words. In the [Deathly Hallows] book, Snape's dying words to Harry were "Look at me". Right then we did not realize the significance of his words but in the very next chapter when Harry goes through Snape's memories in the Pensieve, he comes to know how much Snape loved Lily.
He said, 'According to Victorian flower language, asphodel is a type of lily meaning “my regrets follow you to the grave” and wormwood means “absence” and also typically symbolises bitter sorrow. If you combined that, Snape's words mean “I bitterly regret Lily's death”.
He'd have a hard time convincing his Death Eater friends not to kill her and she'd spend a lot of time hanging around with people who'd discriminate against her blood status. They could potentially have a child, but Snape doesn't seem like the person who'd want one to me. So I'd assume they'd have a childless marriage.
Towards the end of The Deathly Hallows, we learn Snape apologised later on. Unsurprisingly, Lily didn't forgive him and severed their friendship permanently.
Her leaving Snape wasn't a sign of her being a bad friend but rather that their interests no longer clashed as he was studying something that Lily despised. They just grew apart over time, and that was no fault of Lily's.
Later, Snape tries to apologize for calling Lily a Mudblood, but she's not interested; she ends their friendship due to his association with Death Eaters. Seventh Year: James becomes Head Boy and seems nice enough now for Lily to start dating him.
Snape loved Lily deeply: through their years at Hogwarts; through her marriage to another wizard, James Potter; through his time as a Death Eater; and long after her murder at the wand of Lord Voldemort.
During the pensieve scene in Deathly Hallows pt 2, they made it seem like Dumbledore was always aware that Snape loved Lily, he even said "I would never reveal the best of you" or something like that. The entire time Snape was concerned for Lily and Dumbledore knew it.
Dumbledore reveals how thoroughly he loves Harry. Harry is brave, and Dumbledore is proud as any father would be. More than that, Dumbledore succumbs to a parent's weakness; he cares more about Harry's happiness and wellbeing than the wizarding world he is trying to protect.
He hid them using the only thing that would work against Voldemort. He used Fidelius charm and after that even secret keeper was to be protected using that as Sirius said in PoA. The plan failed because wormtail who was their secret keeper betrayed them.
James' rivalry with Severus Snape also started early when he insulted the wizard while on the Hogwarts Express. Since then, James and his friends, also known as the Marauders, taunted Snape throughout most of their schooling.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
Snape, in his insults directed to her, always called her an insufferable know-it-all and targeted her intelligence, but maybe she was insufferable to him because she constantly reminded him of Lily and her know-it-all habits.
Snape even said that he didn't want anyone to find out that he was protecting Lily's child, “especially Potter's son” (pg. 679 of Harry Potter and the Deathly Hallows) because of his hatred for James. Instead of providing Harry a safe haven from his abusive home with the Dursleys, he tormented Harry over an old grudge.
