I suspect the extend and target of postmortem blame varies considerably from culture to culture. An anecdote from the railroad traffic between Germany and Denmark:
"[In 2019, a DB Cargo freight train in Denmark caused an accident with a passenger train on its way to Copenhagen after a truck trailer flew off the freight train due to high winds. The German side was keen to find out who was responsible at the lowest level, i.e. the wagon inspector who had not adequately secured the freight on the freight train. The Danish side didn't care, the local authorities were concerned with structural responsibility. Not who caused the accident, but why could it happen! So in Denmark, the motto is: the process is the cause.]"
