We look to our heroes for inspiration in our daily lives. Hearing about their exploits and adventures provides a sense of awe and fascination. This can lead to a subconscious deification of those who are human beings just like us.
Unless we confine ourselves to fictional characters we have to come to terms that those we idolize are imperfect. This concept goes beyond human fallibility, but recognize heroes sometimes display traits representing the worst humanity has to offer.
People and events are romanticized as time goes on and misdeeds fade into the background. Idols are elevated to superhuman status; thus removing an essential part of humanity, the capacity for evil, as well as good.
There is something to be gained from studying the faults of our idols. Besides the cliche that no one is perfect: the views, errors, and actions that defined them are seen as barbaric by the standards of future generations. As carriers of the tourch, we can understand, and surpass them.
