I take a look at Luke Skywalker's view of the Jedi Way
and why I think after the events of Return of the
Jedi he has been a practitioner of the Gray side of the force.
Note: I know some people consider that Luke did not force choke in ROTJ but rather used a Jedi mind trick to make them think they were suffocating but i consider it very similar to force choke.
Some Fan Art work was used in this video. I do not own the art work.
