The greatest warning from Master Yoda during The Empire Strikes Back has actually been continuously proven wrong by Star Wars' biggest stories. Since the beginning of Star Wars in 1977, a core theme of the franchise has always centered on the light and dark sides of the Force. Stemming from this, a great deal of internal character conflicts has focused on the pull to either the light or the dark side, depending on which side the character begins on.
From Anakin Skywalker and Luke Skywalker to Kylo Ren and Rey, the internal struggle between light and dark has always been a prevalent character arc in the Skywalker saga. This arc was first set up in The Empire Strikes Back, in which Yoda issued a warning to Luke: "If once you start down the dark path, forever will it dominate your destiny, consume you it will, as it did Obi-Wan's apprentice." However, this warning has actually been proven wrong throughout Star Wars, using many different characters and how the struggle between light and dark does not consume them.
