Harry Potter fans can’t agree whether the Potions Master is good or not, but these Severus Snape quotes prove he’s at least a terrible teacher.

Severus Snape is arguably the most complex character in the Harry Potter series. The Harry Potter fandom has never, and will never, come to an agreement on whether Snape is a good person or not. There’s enough supporting evidence for either side to keep this debate going for eternity.

One thing Harry Potter fans can probably agree on though, is that this Potions Master is a horrible teacher. He’s definitely knowledgeable on the subject matter he teaches, but he has no business imparting that wisdom onto children. These Severus Snape quotes prove just how much of a bully he is to his students.

  11. “How extraordinarily like your father you are, Potter…He too was exceedingly arrogant. A small amount of talent on the Quidditch field made him think he was a cut above the rest of us too. Strutting around the place with his friends and admirers . . . The resemblance between you is uncanny.”

  15. “It is Veritaserum—a Truth Potion so powerful that three drops would have you spilling your innermost secrets for this entire class to hear,” said Snape viciously. “Now, the use of this potion is controlled by very strict Ministry guidelines. But unless you watch your step, you might just find that my hand slips”—he shook the crystal bottle slightly—”right over your evening pumpkin juice. And then. Potter… then we’ll find out whether you’ve been in my office or not.”
