That actually is part of what makes Shinobu kind of a disappointing character, Nisio basically just took the concept of Rika and made her into an even more fanservicey but also overpowered vampire mary sue. She's a lot more sloppily executed than the way Rika was and monogatari really fails to play up her two faced nature as well as higurashi does. 
It's my impression that you don't care much for shinobu's true character or her two faced nature since you seem to be completely focused on the donut retard aspect of the character. It may be unrealistic for me to expect you to get what I'm saying.
