Sorry for a slight thread drift, but...
If indeed there was nothing else to be done, despite the best efforts of crew/doctor assisting, then further factors come into play.
The relevant bodies assisting (whether that be QR Ops, doctor on board, Medlink) then consult as to where the most appropriate location to proceed should be. Of course the F/O now in command can make this decision, but imagine you have just lost your colleague. Of course you are going to ask for help to make this decision in such a stressful time and choose the best place for all now that (sadly) saving your colleague is not possible and no longer the priority.
Think that by going to KUL, with a replacement crew available, and possibly better facilities/ease of access to counselling/crisis teams (which QR would know) and also minimising delay to passengers (also stressed) and allowing the traumatised crew to go immediately to a hotel rather than waiting with delayed passengers, may indeed have been the best option.
All we know as outsiders for a fact is that people have lost a colleague, son, husband... so very sad at a young age and all we can hope for is that QR do the right thing by his family
