Pilgrim,

The slave who has been brainwashed into believing that, when he acts according to his master's desires, he is making a "free decision" is still a slave. He is, in fact, worst than a slave because he doesn't even know that he is a slave. Is that your idea of freedom?

By contrast, regenerate man has been liberated by the Holy Spirit to become Christ's slave. To the extent that the Holy Spirit rules, guides, and leads him, he is a freeman. I Cor. 7:22.
