Humans are gonna human, if you have an environment where you fail to account for this, this will happen. Reminds me of a dev dropping a production database, or the aws engineer who incorrectly entered a command and brought down s3: many things have gone wrong to even be at this point, blaming a human for behaving like a human in an inhospitable environment is silly. Effort is almost always better spent building a system which is safer to operate for the people involved.
This is unacceptable behaviour for a professional in my eyes.
