"I believe that psychotherapy would have helped Anakin and might have prevented him from turning to the dark side."
Just tried to imagine Anakin lying on some kind of couch and the psychotherapist asks him to tell him about his hopes, fears, dreams, nightmares, maybe little voices in his head and so on.
I guess it won`t take long untill the psychotherapist kisses the dust wheezing or till he gets broiled by some Sith-lightnings!
Well, that`s a good moment for a first: "I find your lack of faith disturbing!"
