No, accountability is a very insufficient answer, because it helps very little in identifying and fixing broken systems. In a lot of cases, this one being a particularly good example, nobody was particularly incompetent, negligent, malicious, or greedy. But the system as a whole lacked safeguards so that a single person's inconspicous mistake could cause a disaster, and overloaded that person's attention. Sure, there's other cases where you can clearly identify negligence, malice, or greed of specific people as causes of the disaster. But there as well, holding those people accountable doesn't fix the system than incentivised the greed, doesn't prevent incompetent, malicious or negligent people from getting into positions where actions based on those traits cause disasters, and doesn't provide safeguards against such actions. The deterrence value of holding individuals accountable for extremely rare events is approximately zero.
