If you want to find out more about Dianetics and Scientology, the best way to do this is to read an L. Ron Hubbard book on the subject. I personally recommend you read Introduction to Scientology Ethics.
This book really helped me with regaining my integrity. It gave me the tools to regain and maintain a high level of ethics and helped me in aiding others with their ethics and gave me invaluable data on where justice fits in with ethics.
