Psalms 2:10

Now therefore, O kings, act wisely; be instructed and take warning, o leaders (judges, rulers) of the earth.  Worship the Lord and serve Him with reverence (with awe-inspired fear and submissive wonder); rejoice (yet do so) with trembling.

It says that leaders are to give respect to the Son so that he does not become angry and they perish.  Leaders are to represent the Son on earth in an honest manner.  Leadership was supposed to follow the Godly principles of the law, and the Bible handed down by God.  It is when man follows their own way instead of God that corruption of leadership happens.
