Description : Who is snape why would he dislike harry?
Last Answer : Severus Snape is the potions master at Hogwarts. (Major spoilers by the way). Snape was a childhood friend of Lily, Harry's mother. He dislikes Harry because he reminds Snape of Harry's father, ... when they were in school. Snape always loved Lily, and he resented her and James for getting married.
