Its funny, when you think about Clone Wars which bought in the concept of the bio inhibitor chips that forced the Clones to execute Order 66 and later become the hyper obedient Storm Troopers of the Empire.

But if you think about it, while the chips were an excellent plot device to make you almost feel sorry for the Clones, I doubt they were needed.

1) the Clones were conditioned to obey orders from their birth and even before. They would obey their Clone Commanders, Jedi Commanders and unfailingly the Commander in Chief which was Palpatine.

2) You'd have to think that after years of war serving under a lot of inefficient Jedi Commanders that got their brothers killed, Jedi that lead them to slaughter like Pong Krell, and Jedi like Mace who were hostile to the Clones to outright unfeeling that they would have no trouble pulling the trigger on the Jedi when order 66 came down the pipe. After Umbara, I'm sure that word spread about what happened to them.

3) Palpatine was spreading a lot of propaganda that the Jedi weren't really to be trusted in the later stages of the war, it wouldn't have taken much to spread that message to the Military.

4) All the Clones were interested in was winning the war and securing the Republic.

I believe that the Clones would have willingly pull the trigger on order 66 given their orders came from the supreme authority, that the jedi had betrayed them in the past, that the Jedi were willing to throw thier lives away and were poor leaders. That the Jedi were a threat to the Republic.
