Mace Windu believed he was The Chosen One
We know that Mace is aware of the prophecy of the Chosen One and this theory states that he believes himself to be the Chosen One and not Anakin. This is why Mace does not want Anakin to be trained as a Jedi and then later refuses him the rank of master despite offering him a seat on the Council. This is also why Mace tries to kill Palpatine in ‘Revenge of the SIth’ He wanted to single-handedly destroy the Sith, thus bringing balance to the Force and fulfilling the Chosen One prophesy.
