It has been said that everyone/everything has a purpose if only to serve as an example of what not to do/say/be. I agree. Doth thee?

I believe that the sb prez is the VERY BEST EXAMPLE of the very worst in homo saps. He has a lock on that territory forevermore. His purpose is to educate us to the potentialities and possibilities of VERY WORST. He does an excellent job at that. In my opinion. Who does it better?
