Think about this carefully - if universal moral code exists, then such code implies that there are Absolute Right, Absolute Wrong, otherwise there would be multiple moral codes all equally valid. This in turn implies that certain actions are absolutely right or wrong, regardless of other circumstances. For morals to be truly absolute, they would have to have a universally unquestioned source, interpretation and authority, e.g. GOD, and mere humans are not capable of such absolutes.
