DB6 it is a bit ruff.
You would be suprised how many folk out there would bust mins given half the chance. I am not going to get into a which nationality thing but its way more common in certain country's.
It all comes down to how you started you career and the ethos which developed you as an FO.
The FO not enforcing the legal operation is nothing new and will happen again. Gaining an additional 1300 hours single pilot ops will not change this. Its the whole issue with the transfer to Multi crew ops they did try and do something about it with the MCC. But that got perverted away from the intention that it should be done by the company on intial type rating instead of the current tick in the box you need it before you can apply.
I have no doudt the skipper had busted mins before as an FO and I also have no doudt while in the RHS he was flying with mangment pilots when they busted mins.
It wasn't a UK airline or operation full stop.
