At least until the finale, Severus Snape always left us wondering which side he was on.
But one thing we know for sure – he wasn't a happy man.
However, you have to have some fun in life, don't you?
So, what did Snape do to put a smug smile on his serious face?
Not everyone in the wizarding world likes Harry Potter - just ask Filch and Slytherin students.
However, Snape's antipathy towards Potter reached a new level.
He was constantly criticizing "that famous Harry Potter" and never missed an opportunity to embarrass Harry.
And it all stems from hatred: everyone says that Harry looks exactly like his father, and even if Harry has green eyes like his mother, it can't stop Snape from being angry when he sees him!
Snape made no secret of his preference for Slytherin, and Slytherin students enjoyed Potions classes the most.
This is the so-called "two-way love".
In contrast to the Gryffindor Headmaster's fairness and strictness towards every student, Snape often turned a blind eye to the bad behavior of Slytherin students.
Especially when Slytherin people stir up trouble, Snape usually deducts points from his own house.
In Harry's first Potions class, Snape said something like this:
I don't expect you to really grasp the beauty of the simmering cauldron of white smoke and fragrance, and you don't really understand the magic ......of the liquid that flows into people's veins, the magic of the heart and mind”
In a poetic, almost romantic way, Snape taught the first-graders about the art of potions, showing his deep love for the craft.
The Half-Blood Prince's old textbooks, in addition to tips for brewing potions, also contain Snape's dark magic secrets.
He has been exploring the dark arts since he was a student, and has come up with many powerful spells, including the terrifying Godless Shadowless Spell.
According to Sirius, Snape had already mastered more foul language when he arrived at Hogwarts than most seventh-year students, and it was clear that he had been fascinated by the dark arts since he was a child.
Snape was particularly "caring" of Gryffindor's students, and could find a reason to punish them almost at any time.
Hermione felt deeply unfair about this.
She was often deducted points for helping her classmates (usually Neville) and answering questions correctly, or, in Snape's words, "an intolerable jack of all trades."
You might think that a potions master like Severus would be able to concoct some magical potions to help him deal with things like his hair.
After all, the most well-known haircare products in the wizarding world were developed by a certain company, and Snape must not be uncommon.
Judging by Snape's oily black and shiny hair, which has been the same for ten years, he should be very satisfied with his state.
What teacher doesn't want to know what is in the belly of a student?
And Snape has the ability to not only see through the troublemakers at a glance, but also to read minds, and even the memories of students.
Snape was one of the strongest Masters of Regency in the world, and students had better avoid looking the professor in the eye.
Snape was the kind of guy who would snicker at the bad luck of his enemies, especially since he had taken the job he wanted most.
Gilderoy Lockhart made a public fool at the dueling club, and I have to suspect that Snape did it on purpose, haha.
Of course, the other Defence Against the Dark Arts professors didn't get Snape's good looks either.
Using a curse to trick someone else would be "too childish" for Snape.
"Irony in the face" is Snape's truly irresistible black magic.
In the movie, Alan Rickman vividly interprets Snape's hidden and creepy tone, cold, sharp, and mean, ......
I have to say that satire is the highest level of black humor!
Snape may have had many preferences, but the one that really made him love was undoubtedly Lily.
You only have to look at his Patronus to know that his love for Lily is "always" even as the years go by.
Although Lily has been dead for many years, her place in Snape's heart has never changed.
In the long and lonely years after Lily's departure, those fond memories will make Snape smile most truly and purely.
