Sisterly Lust (Liza), Depraved Awakening (Mi-do), Urban Voyeur (Sophia), Parental Love I guess (Sofi). Ecchi Sensei has some damsels in distress too (sorta). Also, Big Brother (but in that game I don't know who the most abusive character is).
Edit: forgot Chloe from Saving Chloe (to better appreciate her character, I suggest you play the whole Elsaverse saga).
