It seems to be part of most people's human nature to admire and make icons out of people. I couldn't see myself doing it but when I was young I did idolise some public figures and would have been terribly disappointed to find out negative things about them. My 'idols' were on the left or involved in the Peace Movement or maybe somebody working for the Iona community about which Anchorman has started a thread.
It doesn't last, all people have feet of clay and we really know that.
