Seems to me if you are rigidly limited to what is PROPER in one area you are obligated to always be and do what is RIGIDLY PROPER in all areas of life and in all things. Which means don't cheat on your taxes , don't go faster than the posted speed limit. If you get more change back that you should give it back. Don't cheat on tests. Don't plagiarize the work of others. Don't take credit for something you don't deserve. Don't take cuts, wait your turn. And so on. Consistency. Dependability. Purity of thought and action.
