Sidous' minion is the one who contracted with Kamino for the Clone army (Dooku masquerading as Sifodius most likely). The clones were conditioned per his orders. They were not turning on the Republic, they were turning on the Jedi whom Sidious had maneuvered into appearing to be trying to overthrow and control the Republic. So it may have been something akin to a "switch", where they were conditioned to be ultimately responsive to him, and told of his "concerns" about the Jedi, and so ready to turn on them at his order.
There is some interesting backstory here and there about it, as in the campaign mode in the Battlefront II game, where the clone narrating the game talks about not liking turning on their generals, but it being their duty.
Back to my less geeky pursuits.
