I know many physicians, nurses, and, unfortunately tort lawyers.
There is no comparison between the ethics of these groups.
I work with the medical profession and I know their ethics are caculated on a profit level.
Like all professions, there are some really ethical and good men and women in medical profession. But business is business and if you remove a cost for malpractice, you will see more of it. They are not a priesthood of self denial for the sake of humanity. They operate to make money.
