Suppose you think it is immoral to do X (fill in the blank with something you think is immoral) but you are actually a bit tempted to do it. Why refrain?
A) Because doing so makes the world a better place to live for me and others whom I care about.
B) Because an authority figure (worldly or otherworldly) may well catch me and punish me.
C) Because it is (objectively) right to refrain, and I prefer doing what is right.
If you picked (C), why do you prefer doing what is right?
