I believe we are made in the image of God, so we are fundamentally good. However we are tainted by whatever our personal circumstances may be and have fallen into the delusion that are we separated from God. As a Christian, I believe that Jesus points out that God always comes to meet us in our darkest hour and shows the way that we were meant for much more. It's not that we're so tainted and need to be "fixed" as that we need to be reminded of our worth and potential.
