It baffles me how such people can do so well in life. Shame is the most effective tool we as a society have to protect ourselves, yet we don't use it. Regardless of how smart and adept a person is at their profession, if they lie, steal, cheat on their spouse, etc. we should know it. We should know who amongst us cannot be trusted. I for one would not want to employ, rent, or sell to a person so flawed in their character. Tolerance of bad behavior inspires continued bad behavior allowing people to succeed even to the highest offices in the land. Exposing them before they hurt others is our best protection and the right thing to do.
