I think Enron makes a good example: because they had insulated themselves from reality for so long, they convinced themselves that what they were doing wasn't really that bad until it was clear it was going to collapse, at which point they were already fucked. Also, a lot of those people got away with it because they left before the fraud was uncovered, despite being part of it. And there are more than enough examples of people getting away with it completely. Fraud has been uncovered by banks in the past couple of years and they just gave the corporation a fine, not jailed the people involved in it. KPMG got away with tax fraud by paying a fine, too. In fact, it might be the case that you're far more likely to get away it than not:http://people.stern.nyu.edu/msubrahm/papers/M&A.pdf.
I don't see how a CFO wouldn't see the issue with "mark to market" and showing potential future gains as current profit.
I am a little fascinated with Theranos because it seems like more employees (vs just leadership) seemed to be aware of, or participating in, the deception.
Almost makes more sense in the Enron case, as the people committing the fraud all had so much more to gain.
