Your determination of what is right or wrong should not be based on an absolute moral law or the prevailing morality. Because truth and reality are perceived differently from diverse points of view, no single point of view is the complete truth. All points of view are inherently biased, and vary over time. A moral judgment should depend on details of a particular case and its social context.
When making choices about personal right or wrong behavior, carefully assess and evaluate its possible consequences to yourself, to others, and to society.
