She was the most manipulative, infuriating and hideously dressed woman in the entire series and her medieval methods of torture that she inflicted on students in detention was enough to make a Hufflepuff use the Cruciatus Curse on her. She deliberately branded Harry as a liar about Voldemort's return simply because she's an ignorant mud blood. Please excuse the bad language, but she deserves it. At least Voldemort cared about Harry's education because he never once tried to kill him under after he had sat most of his exams.
