The Dark side can make one forget why they're doing things in the same place if they're at too long or enjoy it. Their motive changes from something meaning well to standard evil. Thing about Star Wars with Anaking Skywalker for a good example or Lucien from Fable 2.

There are some expections though like in Mr.Gold who never forget why he did everything he did for 200 years no less. Hell in the universe he hails from It's the evil characters who are shown to remember everything, while the "good" characters have forgotten their identities.
