Of course, in practice many medical ethicists' work is to limit any legal and financial troubles for the organization they work for. In the ideal scenario, thir focus is to "do no harm" and to be minimally intrusive to the lives of the patient.
Like many fields, individuals in this field walk a line being pulled by their financial influences and the ideals they've been trained on & expected to uphold.
