Another issue to consider is a crew where the surviving pilot is a weak MPL First Officer.
I surely would not want to be riding as a passenger westbound at 60W with a deceased Captain, SATCOM and CATIII MEL'd, the HF at 1 x 5, and with eastern Canada in a blizzard and most of the US east coast <2400 RVR.
Enjoy the ride. Your MPL is going to decide where to land, and attempt to hand fly a CATII approach with a dead body on the floor behind him.
Great system we're setting up with commercial aviation.
