In a way.....Luxu is telling the truth. He wants to do what's right by defeating darkness, so he follows the Master's plan. It's not really moral, but it is what he considers right. And even with that, Luxu occasionally does show instances of defying the Master's orders, such as with Brain, the True Dandelion (Strelitzia), and Skuld, giving them another chance to live.
OH MY GOD- AFTER ROUGHLY 42 HOURS THIS BAD BOY IS FINISHED!!! SO HAPPY WITH HOW THIS CAME OUT DEFINITELY AN IMPROVEMENT FROM THE FIRST TWO TIMES
