Just to add-in, my theory is that Oliver signed on because it was all part of his plan. He joined the League because he realized that this was his best bet at defeating Ra's once and for all (only the student has hope of defeating the master). I feel that once he has done all that he needs to, he will turn on Ra's and finally defeat him, thus ending his reign and coming back home, helping Barry face Eobard, and restoring his relationship with his friends, now an even better Arrow than before. Again just a theory, but I don't think the mind wipe is having any effect on him. Remember how Season 2 ended? Turned out that Oliver had found Slade's cameras and orchestrated things so that Felicity could hit him with the cure.
