I do think there should be a "death penalty" for companies, but you don't need to punish the company (and many innocent employees) to prevent unethical behavior.

Instead, you need to:

1) hold the C-suite and the Board accountable for the crime(s)

2) eliminate all their compensation from the years they were committing the crime

3) force the company to replace the entire C-suite

Fining someone like Zuckerberg and letting him retain control is like finding out your babysitter is giving your child alcohol, fining them, and then letting them continue watching your child. It makes no sense in any other context.
