In order to do what is right, one must know what is right.
I believe that nearly everyone knows the difference between right and wrong.
DO WHAT IS RIGHT.
You do not need a lawyer to tell you your moral absolutes. A strong and unbending moral will, while commendable, is not enough to ensure a moral life. Equally important is moral intelligence. History testifies that blind, misguided will and conviction can cause incalculable damage (the Crusades, the Inquisition, Naziism, Islamic Extremists. And unless we avoid it extremism in the USA). We need to stop being surprised when someone does and the right thing and start expecting it.
When ever I hear someone giving a monologue on their ethical behavior- you can be pretty sure they know what they did was wrong
