We all know that Palpatine recognized Anakin's prodigious skill and power in the Force soon after first meeting him and made it his duty to take Anakin under his wing in order to eventually turn him into his Sith Apprentice. But did Palpatine believe or even care that Anakin was supposed to be the chosen one? First, I'd like to point out the necessary role that Palpatine needed an apprentice to fill for the final stages of his plan: he needed someone powerful in the dark side to assist the clones in slaughtering the Jedi and to eliminate any surviving leaders of the Separatists as it would have been too risky for him to do it himself(although his plan would have not been effected negatively if the Separatists would have been defeated by the Republic's war effort first). He also needed a Sith Apprentice to keep the massive Military as well all of the Galaxy's citizens in line as it would have been too damaging to his image for him to do it himself and he also had no wish to do it anyway as he wanted to focus solely on his studies of the dark side of the Force. So it appears to me that Palpatine needed an apprentice for this point exclusively and the role that Dooku would eventually take was not meant to complete the final stages of his plan nor to proceed as second in command of the Empire. Dooku's role was obviously meant to lead the Separatist movement and was required to be a Sith(or as close to a Sith as possible as Dooku is arguably not a full Sith Lord) because Palpatine needed someone to represent his interests and enforce his will who he could trust to do so and who was loyal to his cause. The Separatist movement would have most likely failed if the corporate powers behind it would not have united against the Republic in the first place or cowered to the Republic's demands/authority. Or the Separatist movement could have been organized and led by someone who was a legitimate opponent towards the Republic which would have taken away Palpatine's authority, ruining his plans to control both sides of the war. Perhaps most crucially this person needed to be a fallen Jedi who could later be used as a scapegoat in furtherance of Palpatine's false assertion that the Jedi were the ones who had wanted to overthrow the Republic although it is possible that Palpatine could have convinced the Senate that the Jedi were in control of the person or merely had grown power hungry and disloyal during the Clone Wars and sought to use the chaos to their own benefit. Both of those scenarios however could have been disproved through investigations or simply could have been perceived as having no foundation in fact so a fallen Jedi was needed to cement/boost the credibility of Palpatine's claims that they wanted to overthrow the Republic and their extermination was justified. In order for this to work of course, the person needed to be killed by someone loyal to Palpatine as the Jedi killing him would not have made sense ( Note: if Anakin had not been burnt he would have been portrayed as the only Jedi who remained loyal to Palpatine's cause given he had "no knowledge of this plot"). So we can determine that Palpatine had significant need for an apprentice to complete the Sith Grand Plan and to become an important figure in the operations of the Empire. This concludes me to believe that Palpatine did not want Anakin because he was the chosen one and did not carve out the role he would eventually give to him after his discovery of him. He needed someone to fill this spot who was extremely powerful and Anakin was basically gift wrapped for him and who also happened to be even more powerful(or at the very least had the potential to be) than the standard qualifications of the apprentice that he needed at this stage and for the future. So no, I would conclude that Palpatine did not care or perhaps not even believe that Anakin was the chosen one. What do you think?
