I had an Ethics professor in uni who would ask his intro classes to raise their hands if they thought they were a morally upright person. On average, much fewer philosophy majors would raise their hands, and they would continue to decrease throughout their studies.

Of course, the thought process of "I'm trying my best, but sometimes failing", could push someone in both directions of the answer, but striving to be better only works when honestly acknowledging failures. In my experience, the majority of people tend to construct their moral views conveniently along the lines of their preferred actions, but principles built on convenience usually don't hold up to scrutiny.
