Why do they write best when they suffer most?

We see that Satyam chairman, Ramalinga Raju, has resigned over accounting fraud at the Indian outsourcing company. If you google him or Satyam, you will find a copy of his resignation letter. In it, he writes passionately and personally to his board about his "tremendous burden" while he unloads his conscience and resigns. In his pain and humiliation he writes from the heart and with easy-to-read text, including parallel structure. We wish he only would have used more active voice and stayed away from the "mistakes were committed" style of confession. Why is it that business people only write like human beings when they must apologize for their errors?
