This is absolutely incorrect. It runs counter to every high functioning safety culture I've ever encountered.
The system allowed the human to take the incorrect action. If your intern destroys your prod database, it's because you failed to restrict access to the prod database. The remediation to "my intern is capable of destroying my prod database" is not "fire the intern" it's "restrict access to the prod db".
Even the best trained humans will make errors. They will make errors stochastically. Your systemic safety checks will guard against those errors becoming problems. If your safety culture requires all humans to be flawless 100% of the time, your safety culture sucks.
So no, this isn't a fault with a human. Because this was a possible error, it was inevitable that at some point a human would make that error. Because humans never operate without errors for extended periods of time.
