I'm not sure how your comment relates to what I said. But what I understand you to be saying is that there is no necessary correlation between the moral validity of a goal and the efficiency with which it is pursued by a rational agent. The efficiency with which the Nazis murdered millions of Jews and other undesirables is certainly empirical support for your assertion.
A very thoughtful high school teacher of mine used to say that democracies are always inefficient in enforcing their laws, and that that was a good thing. For example, to efficiently enforce laws against the abuse of children the authorities would need to place surveillance equipment in everyone's home.
