I saw this video where someone put all of Snape’s scenes from the eight Harry Potter films in chronological order of Snape’s life, so it starts off with him as a young child to his death. And it’s actually pretty clever and shows Snape in a different light. Instead of seeing him as a bully or arrogant man as we usually do from Harry’s perspective, we see him fall in love with Lily, Harry’s mom, and lose her to Harry’s dad and then death. Then you see him risk his life trying to protect Harry and his friends. Tie a rather moving soundtrack that this person added into all of that and the movie is rather moving. All this perspective is in the books and films, but it’s split across the entire series, so I would overlooked Snape’s actual intentions and believe that he was not truly protecting Harry.
