I recall watching a divorce attorney in court who, I felt, was truly an embarrassment to not only the legal profession, but mankind as a whole. By the time he was done arguing in court, he had upset the judge, opposing counsel and, from what I saw, even his client. I wondered how he treated his coworkers or even his family.
The etymology of "Integrity" comes from the Latin "integritas" which has several meanings - soundness, wholeness, completeness.
I firmly believe that:
--- It's delusional for attorneys to think that they can separate their personal and their professional lives.
--- It's delusional for attorneys to think that they can separate their personal and their professional morality.
Aristotle explained that "the man, then, must be a perfect fool who is unaware that people's characters take their bias from the steady direction of their activities. If a man, well aware of what he is doing, behaves in such a way that he is bound to become unjust, we can only say that he is voluntary unjust." (Ethics 91)
If you are going to be a good person, always be a good person.
Legal issues are hard enough on our clients. Attorneys don't need to exacerbate the situation being the scum of the earth.
