The final battle

I'm now at the final battle scene where the rebels are trying to destroy the death star but Han and his group has not been able to shut down the deflector shield from the moon of Endor. Meanwhile Luke is resisting the urge to pick his light saber up to kill the emperor or Vader. Doing so would mean giving in to the dark side. The last chapter ended with him watching the rebels getting attacked badly and making the decision on whether to kill the emperor. Conflict. What a powerful one this is. So how will it end? I can only find out tomorrow night when I move on to the next chapter.
