Actually Damodara Pandita was the eternal servant of the Lord. He could not punish the Lord at any time, nor had he any desire to, but He did give some warning to the Lord so that others would not blaspheme Him. Of course, He should have known that the Lord is the Supreme Personality of Godhead and is free to act in any way. There is no need to warn Him, and such an action is not very much appreciated by advanced devotees.
