Business crime lessons

Do you think it's a good idea to require all white-collar criminals (see Madoff and Jeff Skilling of Enron) to give, as part of their jail sentence lectures at business schools on corporate ethics? I assume that even if these guys haven't regretted their actions by then, seeing how a former high-paid executive who conducted fraud ended his career and how he justifies his actions years later can be a powerful lesson to students of business. Just out of curiosity, why are all white-collar corporate criminals men? Is it because the field is male dominated or is the nature of women to be honest when they run a company?
