I believe KC made a huge mistake by keeping her personality very similar to her book and Disney counterparts. The QoH is not only a Disney villain/main antagonist of the Alice in Wonderland book, but also one of the most annoying and unlikable antagonists in literature and animation. In MGE she hasn`t even been implied to have any redeeming qualities whatsoever, she`s still the same tyrannical narcissist who abuses her power, and it feels somewhat out of place to have a very unlikable character be aligned with the mamono.
