You don't want to abuse Purin because as you said she does it herself. But it doesn't make you happy. Why? Because her abuse is from a place of self hatred inflicted on herself, by herself and thats not something thats attractive even for ryonafags such as yourself. Self hatred is repulsive. You'd rather take care of her, raise her self esteem and make sure shes in a better place mentally, physically ect. only after that THEN you will feel comfortable beating the shit out of her because its either an "act of love" on your part or the fact you don't like the idea of breaking something that was already broken.
