There was no need for hindsight in this case.
In fact I suggest reading the TSB report again:
Transportation Safety Board of Canada - AVIATION REPORTS - 2009 - A09A0016
The S-92's gearbox failed dramatically during as loss of oil test in August 2002 - 6 1/2 years before it failed in Canada due to loss of oil... and the studs themselves had failed in Broome in July 2008 too.
If that was a failure of foresight it was a far more fundamental failure of technical competence and professional judgement.
Alternatively
if it was a calculated choice, then there is a significant moral and ethical dimension.
