If you don't think the decision makers are considering the cost to the business (as represented in the fine) or the cost to themselves (as measured by a bonus) then whet do you think is motivating their decision making process?
Decision makers are often quite sensitive to the cost to the business, people who are tagged as causing $25 billion in unnecessary charges would need to start talking very quickly about what justifies the expense. Even in the case of Facebook that much money is more than enough to start swinging decisions.
Sorry but it sounds like you think "limited liability" should only be understood to refer to corporate debts and bankruptcy proceedings and that "corporate personhood" should be understood as a legal fiction to make things simpler for bureaucrats.
That's crazy talk. Did you miss the part where corporations are actually people?
Corporations don't make decisions, individuals do.
You could argue if we hit the business hard enough, the individual making those decisions maybe suffers from.. maybe... less bonus? but, well....
