I've read many of blogs that keep saying that Anakin's Turn to the Dark Side was caused by Palpatine or Padme and all this other stuff but my opinion is that it was his choce. it was his choice to join Sidious, it was his choice to betray the republic and kill all the Jedi. He could have turned back if he wanted to buy he didn't, he kept going with the Emperor. The Choice was entirely his. So please comment me and tell me your opinions.
