We are inherently irrational creatures susceptible to dozens of cognitive biases. As a consequence, we are very good at rationalizing things we want to do but would otherwise judge wrong. That was the point neild was making - in that context, saying you will "just not lie to myself" does not address his point.
In the sense I meant it, it does, though I guess my comment was ambiguous. I believe I am sufficiently introspective and aware of my own biases to determine whether I'm making such a basic rationalization, especially when the question is made explicit. If I make the question to myself explicit before pirating something, I feel secure.
