Captain Wood said FO Akers should have requested another pilot take over for the return trip to Exeter because of the "massive" fall-out between the pair and that "He chose to put the safety of innocent passengers and crew members at risk by operating the return flight.".
It should have been the Captain's decision to offload the FO (being responsible for the flight, and with the legal power to offload
anybody)- not the FO's decision to offload himself.
... and I think I would certainly offload an FO offering a bout of fisticuffs in the carpark!!
