If I ever got a chance I'd just freaking kill
Mrs. Joe from Great Expectations. Although Great Expectations is my second favourite book I still can't imagine her surviving till the end of the book. Good she died earlier. Deserved it.
If she hadn't, I'd throw that book in fire and go into meditation for 3 days to reduce the anger she caused in me and then find someone who resembles her and wound them with my ball pen and pour nail polish remover on their wounds.
