I dont think the fo was being spiteful and thinking the way you speak of. He was responsible for the inintial descent and not getting the descent clearance from 37k until 77 miles, nor did he really effectively pass that along to the captain. He also seemed confused by the lack of radar vectors and stated he wasn't sure how to do the approach without radar? I think he didn't recognize the captain was mentally out of it and in tunnel vision world. The capt never responded to any of his requests or the automation giving him aural warnings. Clasic tunnel vision signs. He seemed to think the capt. Was going to save the approach. I don't think this is expat against local, stuff everybody wants it to be so badly.
