This is never really touched on or referenced after Luke joins Obi-Wan on his crusade and it kind of confused me as a kid. Luke asks his uncle if he can transmit his application to the academy if the droids work out. Then later Luke tells Obi-Wan that he hates the Empire while Kenobi is trying to convince Luke to join him. This is before his aunt and uncle are killed by stormtrooprs. Can someone explain this contradiction to me?
