In life, we often - almost always - have to make our decisions on the basis of incomplete information. Even in the best of situations, we certainly can't see clearly what the results of our decisions would be. The natural result is that we make mistakes.
It is a testament not only to your intellect but to your character that you were able to recognize your mistake and then, rather than rationalizing it as many do, you took action to correct your course.
If it were possible to look into the minds of the upper level managment at Bethel, we would probably see a majority who knew they made a mistake. None of them have the strength of character to admit this - perhaps not even to themselves - and so they become hollow men, going thru the motions from day to day, knowing that this is what they must do to keep a roof over their heads. What a miserable way to spend a life, even if you do have butlers at your beck and call and world tours and adulation. It is all hollow.
