None of us is guaranteed against failure or corruption of any kind witness what's going on in the world in this moment, the follies of human nature and the failures of human nature.
I really believe that all of us have a lot of darkness in our souls. Anger, rage, fear, sadness. I don't think that's only reserved for people who have horrible upbringings. I think it really exists and is part of the human condition. I think in the course of your life you figure out ways to deal with that.
