Palpatine's reason for picking Anakin
We all basically know why Palpatine picks Anakin as his apprentice. The fact that Anakin is the most powerful based on potential and that he has a lot of reasons to dislike the Jedi. But maybe there is more to it than that. At the end of TPM novelization(I know its not cannon, but read anyways) it describes Palpatine/Sidious saying to himself that those responsible for the death of his student, Darth Maul, will be held accountable...or something like that. We know that Palaptine raised Maul from infancy which ment they had to be very close. Maybe as some sort of revenge Palpatine chooses Anakin simply because its Obi-Wan's apprentice. I don't know if Lucas would throw this in, but it could make good sense.
