The first two Jedi we see in the Star Wars movies are Qui-Gon Jinn and Obi-Wan Kenobi. They both have the ability to utilise the force, and as such they can manipulate objects and lifeforms by using their Jedi training. As a general rule, members of The Jedi Order are peaceful and believe in serenity and take a non-aggresive stance unless there is no option. However, when the Old Republic starts to fracture, some Jedi break away from the order and eventually evolve into the Sith.
