There is no positive message. It is very different from the ideals that draw out the best in each of us. It should not be confused with conscience, which is part of what makes us human. Conscience is a gift of God and has an in-built wisdom that can guide us to appropriate behaviour. You are a hypocrite.
Nothing really changes.
Some Christians would point to another possibility with the demonic - the dark underside of spirituality. This is an area that makes me even more uncomfortable, and I claim no expertise. It is all my fault. I think that the Inner Critic, because of the developmental history, will feel like it has been woven into the fabric of personality. But it is alien and this recognition can help in dealing with the problem.
