Purdue is already convicted of a felony. You shouldn't be able to declare bankruptcy to dissolve damages from a felony and felony conviction of company should hold directors accountable for damages.
While it’s unfortunate bankruptcy code wasn’t designed for these edge cases, I’m optimistic about how a court will handle this. Even more so about criminal charges that will likely include a prison sentence due to the amounts involved and clear intent.
Bankruptcy exists as a safety net for failed capitalists.
