Have faith boyz.....
I have the answer from a leaked source.
According to my source, there is a flashback scene that will ?fix? much of what people didnt like (at least about Luke?s arc)
Apparently , we will get to see younger Luke in high gear action fighting off Kylo and the Knights of Ren. He has a longish battle scene, fighting the Knights culminating in the collapse of a building (on him). This occurs directly after Kylo coming to him in his sleep)
During this battle Luke uses his force powers to take on all the knights. However, during this fight Luke is forced to kill one of the knights whom end up being a smallish kid who was enamored with Kylo because of his heritage. This act causes Luke to give up his saber and go into exile. (Along with Kylo and his failure to properly guide him, which resulted in this child?s death.
It basically shows Luke as the opposite of his father in killing children, while giving him a stronger reason to give up directly fighting anyone with the force....and attempting to stay out of the conflict because he saw he too could kill children for a ?cause?
