Lots of distance between small monetary fines and a death penalty. I would settle for executives and board members going to jail when they do crimes.

Any penalty less than the profit, isn't an effective penalty, and won't act as a deterrent.

The Securities and Exchange Commission (USA) has a history of giving million-dollar fines for crimes that produced billions in profit and/or took billions away from victims. And the lack of deterrence has been reflected in the actions of the US financial industry.

Penalties that scale off the offender's income/revenues work a lot better. They're common in some countries.
