Sorry, A330ETOPS, but the relevant phrase that springs to mind here for the deep ops is "**** or get off the pot".
If some of the people working there can't hack it, then they're doing absolutely the right thing by stepping back and saying so - but I challenge you to find a single one of them who says that this work should stop just because it's too much for them...
<conjecture>A330ETOPS has not lost any loved one(s) in uncertain circumstances and/or where A330ETOPS would like or need their body(ies) to be interred, cremated, sanctified or, in some other way, put to rest but this was not possible. </>
