All that stuff you talk about here about design principles, testing, etc., don't actually work when the people at the very top, both at the manufacturer and at the FAA are actively working to undermine it. That's why people have to be punished. We're not talking about a case where some rank-and-file engineers were a little lazy, or where some worker on the assembly line screwed up; we're talking about a case where the top executives directed the entire company to design an unsafe plane, and then collaborated with the regulatory agency to certify it as safe even though it wasn't. You can't fix that with processes, the way you can deal with errors by lower-level people. You have to hold people accountable and punish them, because these actions were willful, criminal negligence.
