Yoda was right. Anakin needed to be willing to let go. Yoda is so right that Anakin is even the one who caused her to die. Yoda was right when he told Luke not to go to Cloud City, but Luke did it because he was afraid to lose the people he loved.

First, Anakin did not commit all of his heinous crimes because he was unwilling to "let go." Anakin was a self-centered, psychopathic jerk who killed little children over absolutely nothing that could even be slightly construed as good. The life of his wife and mother were just selfish lies that made the little bastard feel good about himself as he killed babies.

Second, attachment and possession is what happens whenever people fall in love. It's impossible to not have attachment and possession and still have anything close to real love. Just because any action can be done in an evil way doesn't mean that you throw out the baby with the bathwater as Yoda does in his teachings.

Thirdly, to the degree you can argue about who was right in Empire's plot line. Luke was the hero and more portrayed as "right" by the movie than Yoda was. In the end helped his friends and got away with his life. Yoda was only portrayed as right to the degree that Luke may have been taking too big of a risk.
