I have never hated anyone, not even in real life, as much as I hated Bellatrix Lestrange for what she did to Hermione in the 7th book. The part when she carved "mudblood" into her skin. I cried more than ever when I was reading that scene, and everytime hermione screams, I would scream with her. And everytime I would see Bellatrix I just feel like shoving something through her and slicing her up, watching her scream and hurt the way she made hermione scream and hurt. Because she deserves it more than anyone else. I always felt that the other characters, even the bad ones, had a good side, no matter how tiny, a weakness somewhere...a heart. But somehow Bellatrix never gave me that impression. She was just pure evil.
