Something's been bothering me for awhile. Everyone keeps talking about how Darth Vader redeemed himself and turned good at the end by killing the emperor to save Luke. Now, at first I had no dispute against this. But after watching the prequels and playing the video games like "knights of the old republic," I have started to think less of this so-called redemption. According to the story palpatine told anakin about the sith lord, as well as the KOTOR games, it was common practice for sith to kill their masters. The sith would be trained, and they were expected to turn on their masters when they thought they were strong enough. Doesn't this make Vader's killing of the Emperor look like just another sith surpassing its master? I was just wondering if anyone else noticed this, or thought the same way.
