People that chose to ignore that voice often don't think they will be caught so no consequences can flow from their actions. We lock them up because they lack the sense that what they did is wrong and the overwhelming probability they will be caught. Laws are to keep order not enforce morality.

Women do have a right to privacy but humans have a right to live.
These two right clash so we are forced to choose one over the other. I believe that life should trump all rights.

It was fought to combat the spreading of Communism.
