In a case like Enron, based mainly on testimonies and analysis of past fast, sometimes is difficult to decide who you believe. I always thought all of them were guilty, I mean the top executives. However, as the trial goes on, I am starting to differenciate two different types of guilty.

The second one is where Skilling and Lay are. They know they had done bad things, but they'll never admit it, they will continue with the theory that they didn't know anything about the operations that finally drove Enron into bankruptcy. They continue lying (in my opinion), smiling and posing for the picture. Furthermore, they pretend to make us believe that they are the victims in this story, that they found themselves involved in this scandal without knowing anything.
From my point of view, it is much more honest Fastow's attitude, he knows he destroyed his life, he is ashamed of what he did, but he regrets it, he stands up, assumes his faults and asks for forgiveness.
