Anakin never wanted to turn to dark side?
From some of the scenes we've seen from the tv spot "to protect you" it almost seems like Anakin doesn't want to turn to the dark side for some of the reasons we might think. Regardless of how evil Anakin became it all could just be confusion on his part and not knowing what to do thats why we see several shots of him crying, telling Padme he's doing this to protect her and another shot of him looking away in heart break while he's kneeling to palpatine. So if you think about Anakin could of turned to the dark side for just 2 reasons a) to save padme as we all know and b) he had no choice after he turned and and was saved by Sidious and became mechanical he knew he couldn't leave the dark side b/c Sidious would kill him. All these plus Anakin returning to the light side in EP.6 can be signs that Anakin never really embraced or wanted to turn to the dark side for more power or because the Jedi didn't trust him or embraced his abilities.... In Anakin's mind it all could of just come down to 2 things Padme and lack of choice.
