When sacrificing the bishop in that situation, there are a couple things to look for. Of course it's great to take away castling privileges but that on its own is not always a great thing. You need to have some development and be in a position to attack, either threating mate or winning back material. In this situation, white has not developed any pieces other than his queen. And with counterplay, he'll get stuck moving that queen around even more just to keep it safe, which allows a lot of development for black.
