Snape seems to be the type of person who fears concepts that are hard to personify (like guilt, failure, and abandonment). I imagine his boggart to take the form of Harry dying as that was his way of doing Lily any remaining good and fulfilling a promise.
All of Snape's biggest flaws can be explained by the fact that he was selfish and self-serving. Yes, he did help Dumbledore, and he was instrumental in taking down Voldemort. However, he only did this because he himself was hurt by Lily's death.
A notable exception is Snape, whose boggart is never revealed, despite being such a key character in Harry Potter due to Snape's villain-to-hero character arc.
Neville Professor Snape Neville fears Professor Snape who treats him rudely with sarcastic comments. Neville seems afraid of this harsh treatment that makes him feel inferior constantly.
That's who we really are." I believe James Potter did make some mistakes as a teenager, but overall he was a good man. Yes, he did bully Snape but so did the other marauders like Sirius - Remus wasn't really any better - did he stop James from bullying Snape?
Thus, the answer is simple - Snape mistreated Neville as he was nearly the chosen one. Had Voldemort picked Neville instead of Harry, Lily's life would have been spared. Snape relieved his dark past through Neville Longbottom and therefore resorted to mistreating and insulting the almost-chosen one of Harry Potter.
Bellatrix's greatest fear was : abandonment by her Lord Voldemort. Bellatrix is a blind and die-hard servant of her master Lord Voldemort. She was seen to have been greatly taken aback when Snape mentioned that she wasn't Voldemort's best servant.
But when Scorpius shows that he knows of Snape having been in love with Lily, Harry's mother – Snape's most closely guarded secret – Snape becomes convinced that he does indeed come from a different timeline where Harry and his friends won.
Much of what is known about the characters' Boggarts comes from the video game, LEGO Harry Potter: Years 1-4. In this game, it becomes clear that Draco Malfoy's Boggart is Lord Voldemort. Draco's fear of Voldemort likely comes from different reasons than others have.
There were many things Snape actually liked, but probably only one he ever truly loved. Look no further than his Patronus, which remained a doe even after all those years.
Sectumsempra is a curse invented by Professor Severus Snape, during his childhood, when he was known as "The Half-Blood Prince". He created it with the intention of using it against his enemies, and it soon became one of his specialties.
Sectumsempra was a curse invented by Severus Snape that lacerated the target and caused severe haemorrhaging. Snape created it as a student of Hogwarts, with the intention of using it against his enemies, likely including the Marauders, with it becoming one of his specialities.
Like most archetypical villains, Voldemort's arrogance leads to his downfall. He also suffers from a pathological fear of death, which he regards as a shameful and ignominious human weakness. According to Rowling, his Boggart would be his own corpse.
Among the most admirable traits of Hufflepuffs in Harry Potter is that they will always be caring toward their families. This leads to a fear of losing their loved ones, and Hufflepuffs can't be comfortable with the knowledge that the people they love are in danger while they sit idly by.
Gryffindors show a fear of being perceived as inferior, which is mainly due to their inherent need for glory. The students were usually shown stressing about losing to Slytherin each year, but it was at its peak in Harry's first year because Slytherin had beaten them for six years running by that point.
Barty Crouch Jr. despises Draco Malfoy when they meet in Harry Potter and the Goblet of Fire, and there is a good reason why. In the fourth Harry Potter film, Barty Crouch Jr. is enlisted by Voldemort to infiltrate Hogwarts to get closer to Harry Potter.
J.K. Rowling says Draco doesn't have a patronus because he never learned the spell but I think it's because he doesn't have any powerful happy memories to use.
Malfoy was born in a pure blood family and had no doubt heard of the baby who defeated Voldemort, which would have intrigued him. Therefore he tried to befriend Harry, but came off as rude, which got him rejected. He then proceeded to bully Harry and his friends to avenge the rejection.
Why did Snape hate Hermione? I think Snape was probably initially impressed with Hermione, but later frustrated with her, for a few reasons. Hermione was very book-smart and could come up with answers quickly, but didn't seem to be very good at improvising or trying to improve on existing Magic.
But what McGonagall doesn't know is that Snape is actually a double agent working for Dumbledore, so he has no intention of harming her. That being said, Snape holds back quite a bit. Many fans, however, like to speculate who would have won the duel had Snape given it his all.
AS Aman Sharma says, Snape didn't want to hurt McGonagall or Flitwick, his colleagues and sometime friends. He used only defensive measures against them, and when they pressed him to the point where he couldn't defend himself without hurting them, he left.
