What’s better: Morality or immorality?

Without reading the description, the obvious answer to most of you would be morality. However, there is often the condition of progressing society. Do you sacrifice morality in order to advance society? Or do you keep the morality and allow society to stay stagnant? Those are usually the conditions of choosing between the two. For me, I care about advancing society, so I’m willing to sacrifice being immoral (within the confines of the law) for advancing society in our IQ, technology, etc.
