I'd do it for the money. In the capitalistic flow of thought, it would be more beneficial to do it for the money, at least on paper. Think of it this way, if you did it for the money, and did a damn good job, you would either: a) Win more or b) Win bigger cases, either way they both provide more $$$. Of course they do it for the money, anyone who tells you otherwise is lying, because they damn well aren't doing it for the good of the world.
