With all due respect, didn't we read the same books???
I mean, I totally agree with your opinion about book Snape and movie Snape being completely different (Alan's Snape is a sweet piece of cake compared to the one in the books).
But, at what point is evidence shown that Snape was racist? I clearly remember that on one occasion he got angry with Phineas N. Black for insulting Hermione, calling her a "mudblood."
And now Snape stood again in the Headmaster's study as Phineas Nigellus came hurrying into his portrait.
"Headmaster! They are camping in the Forest of Dean! The Mudblood—""Do not use that word!""- the Granger girl, then, mentioned the place as she opened her bag and I heard her!"
— Harry Potter and The Deathly Hollows, Chapter 33, 'The Prince's Tale'.
And have you forgotten the context in which he called Lily a "Mudblood"? He was literally being sexually assaulted and humiliated, in front of a crowd that laughed at him. Meanwhile, James flirted with Lily and harassed her to get her attention, even telling Lily that he would leave Snape alone if she agreed to go out with him. Snape had feelings for his friend for a long time (although, of course, it is never specified that were "romantic", but that is another debate), and he did not call her a mudblood because she did not feel the same. Furthermore, we must also not forget the fact that Lily smiled for a moment at the sight of her friend being exposed in his underwear.
"You think you're funny," she said coldly. "But you're just an arrogant, bullying tocrag, Potter. Leave him alone."
"I will if you go out with me, Evans," said James quickly. "Go on... Go out with me, and I'll never lay a wand on old Snivelly again."
Behind him, the Impediment Jinx was wearing off. Snape was beginning to inch toward his fallen wand, spitting out soapsuds as he crawled.
"I wouldn't go out with you if it was a choice between you and the giant squid," said Lily.
"Bad luck, Prongs," said Sirius briskly, turning back to Snape. "OY!"
But too late; Snape had directed his wand straight at James; there was a flash of light and a gash appeared on the side of James's face, spattering his robes with blood. James whirled about; a second flash of was hanging upside down in the air, his robes falling light later, Snape over his head to reveal skinny, pallid legs and a pair of graying underpants.
Many people in the small crowd watching cheered. Sirius, James, and Wormtail roared with laughter.
Lily, whose furious expression had twitched for an instant though she was going to smile, said, "Let him down!"
— Harry Potter and the Order of the Phoenix, Chapter 28, 'Snape's Worst Memory'.
Regarding him considering her "a trophy", I have no idea where you got that from or how you came to that conclusion, but I would be very interested if you explained it to me. As far as I understand, even after Lily had died, he continued to love her and live to protect the child she had with James Potter (his abuser). I don't see how Snape could consider Lily a trophy by carrying out all those selfless actions...
Just in case "Always" isn't enough proof of his deep unconditional love he felt for Lily, I leave you with this other memory of Snape:
And next, Snape was kneeling in Sirius's old bedroom. Tears were dripping from the end of his hooked nose as he read the old letter from Lily. The second page carried only a few words:
'could ever have been friends with Gellert Grindelwald. I think her mind's going, personally!
Lots of love, Lily.'
Snape took the page bearing Lily's signature, and her love, and tucked it inside his robes.
He joined a sad*stic and racist group, yes. But it is shown to us on many occasions his repentance. Even in HP and the Cursed Legacy, he confesses to Scorpius Malfoy that he himself began to believe in the cause Lily was fighting for.
"(...) One person. All it takes is one person. I couldn't save Harry for Lily. So now I give my allegiance to the cause she believed in. And it's possible that along the way I started believing in it myself...
— Harry Potter and the Cursed Legacy, Act 3, Scene 9.
So he was sorry for his mistakes as a bitter teenager, without love or anyone to support him, looking for a place where he would be accepted. Surrounded by bad influences and bad people, he naturally ended up in a cult like that. I think he did more than enough to try to redeem himself. And, come on, let's not forget that he was human too.
About your inaccurate statement "he unalived so many people", at no point is it mentioned in the books that he committed the crimes you accuse him of. On the contrary, he is deeply reluctant to accept Dumbledore's request that Snape kill him, expressing concern for the state of his soul:
"If you don't mind dying," said Snape roughly, "why not let Draco do it?"
"That boy's soul is not yet so damaged," said Dumbledore. "I would not have it ripped apart on my account."
"And my soul, Dumbledore? Mine?"
"You alone know whether it will harm your soul to help an old man avoid pain and humiliation," said Dumbledore.
— Harry Potter and the Deathly Hollows, Chapter 28, 'The Prince's Tale'.
This conversation suggests to us that Snape has not committed such atrocities in the past, otherwise he would not care about harming his soul.
He bullied children, yes. I'm not going to deny that. But let's not forget that he was the one who did everything he could to protect them while he served as headmaster of Hogwarts, risking his life. And you also have to keep in mind that the way he bullied his students cannot compare to the level of abuse by Dolores Umbridge. Snape was cruel to his students, but at least he didn't put them in danger. Not like a certain carelessness of a werewolf. Not like a certain time when a Troll was brought to Hogwarts. Not like trying to erase the memories of two students. So, he cared.
I would also like to mention and remember the time Snape saved Remus Lupin's life, in the battle of the seven Potters, casting a spell on a Death Eater, risking his cover as a spy and disobeying Dumbledore's order about not taking risks under any circ*mstances. He risked his life and his important role as a spy, but if he could save one life, it was worth it. So, once again, he cared.
Also, I should point out that I don't see anyone talking about how it wasn't just Snape who was "painted pink" in the movies. It is also the case for James, Sirius, Dumbledore, or many others. But I guess it's easier to judge and hate someone who doesn't meet the standards of a perfect victim.
Personally, I consider that the Snape of the books, beyond being more cruel, is even more heroic. You can appreciate all its nuances (it has many, by the way), we can judge him more fairly, and even with some empathy, we could understand its motivations (whether for its good or bad actions).
Severus Snape wasn't precisely an angel, but he certainly was a hero.
PD: RIP Alan x2🕊
PD²: I wrote this with all the respect I can muster. It is not my intention to start a war with anyone, I am simply stating my interpretation.
PD³: I'm sorry if something is not written well, English is not my original language.
