When making moral judgments you have to treat society as a single entity. Either that or choose to simply not make the judgments at all. Because there are just too many people in society to calculate the exact amount of good or bad a decision will be to them. Accordingly, you can only really use "it's good for society" if there's a clear benefit. Exposing a chemical company that dumps waste into a town's water supply is a clear benefit. As is making false financial statements in order to inflate your stock to the point where millions will eventually lose their savings. These are clear cases where a whistle blowers in justified. But yes, as far as what's a clear case there is some judgment involved. As my old ethics teacher used to say Morality isn't a math equation it's an essay question.
