When is it right to do wrong?
As we learn, more about the "facts" of reality faith becomes more defined. Faith is different from mere belief in that faith is built on compassion, moral integrity and moral courage. Beliefs can be built on desires, wants and even needs...Compassionate belief systems appear to be built on the search for truth: Whereas, non-compassionate belief systems appear to be challenged by the presentation of truth and of change.
For example, there was a belief held by a part of the Catholic Church quite some time ago that left-handedness was of the devil. About ten percent of the American population is left-handed. This belief was also held by a culture in Japan. In being left-handed in Japan, it was grounds for divorce up until about two decades ago to be left-handed. For the Christian denominations that held to this fallacy it was often based on Matthew 6:3 where it talks about "not letting your left know what your right hand is doing."

There is a famous question in the study of Religious Ethics: "When is it right to do wrong?" Dr Martin Luther King is a living testimony of a good answer to this question.
In your opinion; "When is it right to do wrong? or Is it ever right to do wrong?" (Consider the answer from the Fundamentalist viewpoint, and then from the Conservative religious establishment viewpoint.)
