he wasn't a villain as a Force Ghost, by becoming a Force Ghost Vader is seen as redeeming himself and is no longer a villain.. the spirit is Anakin, the good part of Vader.. basically it's Star Wars version of becoming an angel : Vader as a Force Ghost is a good guy, not evil as he was during his Sith days.
