The FO who rightfully knew they were un-stabilized demonstrated the lack of Command Capability (he was doing his UG I believe?) in taking control of the aircraft, instead thought it better to transmit his essentially useless RT or Inter-cocpit calls. We see the price he and all others paid for that decision. Maybe in this case physical intervention or even a slap on the CPs face would have proven to have been the right choice?
Most humans, barring a few existentialists don't consider death as imminent until they die one day. The F/O seemed to have thought more about protecting the medium term aftermath of an un-stabilized approach, and keeping his job intact.
To do the justice to F/O the death was not imminent at the time he made the apparently self protecting (but post facto determined to be essentially useless) R/T call about go around.
