Devil or Saint?

"If we assert that human brains are nothing more than complex state machines with lots of individual properties and variations - then it's obvious that if someone have the data and algorithms to predict how to alter the current state of individuals into a more desired state - and the infrastructure to deliver state-altering stimuli, then that's exactly what they will do. That's a predictable move. To say that those who do this is evil or saints is just a matter of perspective about the desired outcome."
