It is hard for us to admit we have a sin nature because we live in this system of checks and balances. If we get caught, we will be punished. But that doesn't make us good people; it only makes us subdued. Just think about the Congress and Senate and even the president. The genius of the American system is not freedom; the genius of the American system is checks and balances. Nobody gets all the power. Everybody is watching everybody else. It is as if the founding fathers knew, intrinsically, that the soul of man, unwatched, is perverse.
