Right, the leadership and science teams of Cerberus were all pre-Cerberus Indoctrination, but the military aspect (Troopers, Centurions, Phantoms etc.) are all indoctrinated via implants. Miranda and Petrovsky were "old school" Cerberus who worked, in the (semi) words of Joker: "When Cerberus was less mainstream and...evil." Jacob just wanted to make a difference and never trusted Cerberus, but again, he had a large leadership role.
