He'd also develop a new respect for the power of the Force and how it can be used for good. His growth would inspire the younger Jedi, and he'd leave a mark on the Jedi Order with his unorthodox but effective methods.

For example, the idea of not using the Force for personal gain would be new to him. He would have to learn to use his newfound Jedi powers in a selfless way. He might also find it hard to let go of his dreams of becoming Hokage in a sense, as the Jedi Code doesn't really have an equivalent goal, but he would try to find a new purpose within the Jedi teachings.
Ezra's character often develops in a complex way. As a Dark Jedi, he may become more cynical. He starts to question the values he once held as a Jedi.
