Morality defines what the self interest is, though. Remember, internal interests are still interests. If you violate a moral, you'll have to live with the fact that you violated that moral forever.
But at the same time, self interest defines what the moral is. If, when in conflict, one finally decides to violate their morlas, do they look their morals in the face and say "screw you?" No, they rationalize. For a split second (or longer, depending on the issue), they reason that, in this instance, violation of that moral is acceptable for one reason or another.
So yeah, Justinian, this whole debate is stupid.
