It wasn't until the Clone Wars animated series that it was revealed the clone troopers were under the influence of behavior biochips, which forced them to comply with the order whether they wanted to or not even Captain Rex was temporarily affected by Order 66. Of course, then-Chancellor Palpatine finally saw his decades-long plans come to fruition and he seized the opportunity to transform the Republic into the first Galactic Empire, while simultaneously using his clone army to wipe out the Jedi using Order 66. They were brothers in arms, and they managed to push the Separatists back up until the end of the war - in Star Wars: Episode III - Revenge of the Sith.
