I don't know how it works in the U.K. but in the U.S. attorneys take an oath to provide "zealous" representation. They end up taking a bad wrap for it, but that's the law. Even if they think that their client is a money grubbing, lying sack of garbage.
Although I've never lost a loved one to an aircraft accident, I'm pretty sure that no amount of money they offered could beat back my grief anyway; and I find the idea of discussing money at a time like that unspeakably distasteful.
