The Kaminoan government's product, clone troopers, have chips implanted in their brains from the fetal stage.
Lord Tyranus, who invests a large amount of money, explains that it is a medical measure to calm the clones' emotions. Lord Tyranus explains this to Lord Sidious, but the Sith plot to abuse the behavior inhibitor chip. This is after the death of Magister Damask, the first real client.
In the grand plan, they had devised a plan to prolong the Clone Wars.
A scenario in which the Jedi have prolonged and made it a quagmire. Naturally, the clone army commanded by the Jedi will be exhausted. While showing respect to the Jedi, they will potentially have dissatisfaction with the Jedi. They will become stressed by the current situation where the war does not end.
The behavior inhibitor chip will calm that stress.
Even if they are stressed, they will be forcibly suppressed and made into a product package of an obedient army.
He asks the Kaminoans to activate the behavioral inhibition chips if the Jedi betray them. The Kaminoans cannot defy Lord Tyranus.
He must release the stress in the clones and have them carry out Order 66.
Of course, the Jedi must not be aware of this. (They killed Sifo-Dyas)
You would never imagine that all the clones would have the chips implanted in them from the fetal stage. To the Jedi, the clone army is an obedient product, so they do not feel dissatisfied. They do not realize that the Jedi are dissatisfied and stressed behind the scenes of the war.
Lord Tyranus makes the conditions of the contract that the behavioral inhibition chips are concealed from the Jedi and that the source of funding is kept unclear.
When Order 66 is issued, the behavioral inhibition chips in all the clones are activated. This stops the stress inhibition. The target is the Jedi. This is exactly what would happen if the Jedi betrayed the Republic.
The clone army, who had built up trust over a long period of time during the Clone Wars and had saved their lives and relied on them, instantly eliminates all the Jedi. They take them by surprise in an instant.
The Kaminoans suspect that the client, Sifo-Dyas, had planned the Clone Wars on the Council before he died. At this point, Dooku died, and Lord Tyranus was buried in the dark.
By the way, if the behavioral inhibition chip is removed, it will cause medical damage.
When the Jedi noticed the behavioral inhibition chip, the chairman probably explained that it was impossible to remove the behavioral inhibition chips from all the clones. "The clone army will not be able to fight."
Instead, he will have all the clones vaccinated.
It is a realistic decision since it is wartime. Maintaining military strength.
Lord Sidious was concerned about whether the behavioral inhibition chip itself was defective.
He doubted whether all the clones could carry out Order 66.
Fortunately, the Kaminoans directly explain that there is absolutely no defect in the behavioral inhibition chip. He promised that they could execute Order 66 without any problems.
"The development of an obedient military package was made possible by the behavioral inhibition chip.
The flawless execution of Order 66 will be a medical feat for the Kamino government.
As promised, we can eliminate all the Jedi.
In exchange, the Empire will inherit the Republic's contract."
Lord Sidious and Lord Plagueis were worried about whether they could really eliminate all the Jedi.
Even though they thought they had thought it out strategically, they doubted whether it was medically possible.
The behavioral inhibition chip made this possible. If they had explained it to the late Plagueis, he would have been able to think of a more effective way to exploit it.
