So much corporate/gov negligence leads to permanent environment damage, cancer, death. In most cases it's a slap on the wrist. Maybe some exist, but I'm having a hard time finding an example.

Show me one executive that served this kind of jail time despite direct links to the deaths of multiple individuals and evidence of negligence leading to those deaths.

You can certainly make an argument that the sentencing was warranted but there's a whole lot of history of being sentenced, if at all, to far less for far more egregious crimes.
