Yes, very true. Yet one can still wonder what motivates a lawyer to choose the profession, and actively work with mafiosos whove murdered or caused to be murdered hundreds of people, in some cases securing their freedom through bribery of juries or witness intimidation. To knowingly cause a young girls rapist to get off almost scot free, and laugh about it later.
You also hire a hit man for one reason. One can still marvel at the callous disregard those involved have for other human beings.
A lawyer can choose who they want to represent. They are not required to defend everyone who walks in their door.
Lawyers who defend people like Tony Soprano are most likely only in it for some big money and are probably without morals themselves.
My father in law was a partner in a law firm. He was a very honorable man and turned down many potential clients due to his own moral code.
