because in the end the powers at work will make sure that the blame goes to some person turning a wrench instead of finding the real reason and the real source of the blame, most likely a process or inadequacy of redundancy/checks-and-balances would have been the real fix. Pointing at Max over in Wrenching because he left a wrench in the motor because he's been working double shifts for months on end does not fix future issues, and Hank the Replacement will likely make a similar mistake at some point in the future
