This won't change if the buck can stop with a non-human legal entity. The people who are incentivized to make actively harmful decisions like these need to also carry personal risk for endangering human life. Otherwise it is a decision where the manager who decides to stretch the limits will get praise and cash if it works out, without carrying much or any personal risk — even if they are fined or fired, chances are they already got their share. If we want such things from happening the people taking these gambles need to be painfully aware that it might land them in prison for a long time, and fines need to be proportional to the money earned — that means higher by a magnitude or more so there is not even a doubt that it won't pay off. I like to live in a society where people building critical infrastructure go to prison if they are willingly taking shortcuts.
