Can the advocates help to make India corruption free.?

It is the duty of every Indian to remain aloof from corruption. Of course, advocates can play a vital role for eradicating corruption. However, unfortunately many advocates, many judges are involved in promoting corruption. When a number of advocates, judges are the examples/representatives of corrupt society, (their quantity is not negligible) how can they help the nation in ending corruption? If the farmers, laborers, workers i.e. a class of poor people (who are normally work hard with honesty) come together, then only we can dream of corruption free India.
