Actually, the "Jedi" never proclaimed to be super heroes. The galaxy/republic placed the chore of being protectors onto them because 90% of people do not want to make their own decisions.
This is reflected every day in nearly every country in the world as well as in the fictional universe of GL's making. People like to be sheep, they like to be told what to do and how to do it as thinking for themselves takes too much effort. It also gives them the hypocritical ability to point and blame someone else for their own stupidity in not taking responsibility for their own actions.
The jedi never purported to be unbeatable or omniscient and actually tried to steer clear of trouble.
AND THEY ONLY WENT TO MEDIATE AT REQUEST of other people. Never did they make the choice to interfere themselves, they were invited at the various governments requests to assist in the mediation process.
this thread mentioned yin and yang and balance, then of all the jedi come far closer to spiritual balance (Which is the basis of Yin Yang core belief and of the wheel of life) than most people fictional or not.
Yet, it seems here that quite a few of you are angry at the Jedi, why?
Could it be that you saw them as superpeople and in doing so elevated them onto a pedestal and placed on them your own belief that they should be infallible because they have power/ability that you do not.
Then in effect when they fall, when they are toppled, you are angry because how could someone which you feel is better than you (You placed them on the pedestal and attributed godlike omniscience to them, no one did that for you) it contradicts your own belief in them and therefore you are angry because your view of the world/galaxy has just been turned upside down and you don't like it.
