Am I wrong if I think Karuizawa deserves what happened to her?

Reading the first 3 Vols, my opinion of Kei is that she's a manipulative b1tche, I understand the point that she was bullied a lot in middle school and it got to serious issues but the personality she adopted in high school, clinging to Hirata like a parasite just to be the center of attention and ask him to have a false relationship for “protection of a future without bullying” that nobody even knows about her, being the leader of the girls and adopting a queen bee attitude and looking down on everyone else including the boys in her class and Horikita who didn't have a group in her class, I really enjoyed reading the part about the bullying she received from Manabe's group, it was something like “you reap what you sow”, what's your opinion?
