If governments did not mislead their citizens so often, there would be less need for secrecy, and if leaders knew they could not rely on keeping the public in the dark about what they are doing, they would have a powerful incentive to behave better.

In a democracy, citizens pass judgment on their government, and if they are kept in the dark about what their government is doing, they cannot be in a position to make well-grounded decisions.
