With experience, there were a seemingly infinite number of things a Jedi could achieve through use of the light side. This did not only apply to Jedi, of course, but indeed any Force-sensitive. The Jedi used their powers to gain greater knowledge, in contrast to their ancient enemies, the Sith.

Many people were distrustful of the Jedi Order's great influence on the leaders of the Old Republic.
