Absolutely. Wanting his mother not to be abducted, raped, and murdered by Sandpeople was a bad thing, because that desire led to Anakin slaughtering their village. Wanting to have a wife and child was a bad thing, because it led to him slaughtering the Jedi students. In fact, any bad thing Anakin/Vader ever did can be connected through some tenuous, tortuous thread to him "desiring" something and "not letting go," since that's George's Preferred Moral du Jour.
(Every time I watch ESB now I get shivers. When Yoda claims Luke's flashlight and says, "Mine, or will help you not," he's clearly dancing with the Dark Side.)
Maybe later George will change his mind and decide that Anakin's blond hair was the cause of his downfall, and we can spend hours debating whether it's a profound moral or simply a hypocritical non sequitur.
