Post a female character who u find to be a REALLY/VERY terrible, horrible person and/or even makes u angry at her

Medusa (Soul Eater) is ABSOLUTELY a very terrible, horrible person especially for the many heinous, vile, and wicked acts/deeds she has committed such as her desire to destroy Death Weapon Meister Academy from within through deceit, cunning, and trickery, the mistreatment of her child Crona, and possessing the body of a very young and small girl

Now while Medusa doesn't make me very angry at her, I do feel a little disturbed and perturbed by her actions
