Woodrow Wilson wanted the United States to be a force for morality and good in international relations. This can be seen most clearly in his push for the adoption of his 14 Points at the Paris Peace Conference after WWI.
Wilson wanted the post-war world to be based on morals, not on the pursuit of power. This was his major war aim in WWI. He was not interested in taking territory or punishing Germany or anything else. He wanted to remake the world on a moral basis that would make war obsolete.
Wilson believed that the US should be a force for the realization of his dream of a world order based on morality.
