A database about people can be misused in four ways. First, the organization that collects the data can misuse the data. Second, rogue employees can misuse the data. Third, unrelated parties can steal the data and misuse it. That happens frequently, too. And fourth, the state can collect the data and do really horrible things with it, like put people in prison camps. Which is what happened famously in World War II in the United States.
