Originally William had been under the subconscious impression, that it would have been easy to control a bunch of slaves. That perception altered however, the more he thought about the prime plan.
It was an option to target a few thousand people, and manipulate them mentally or emotionally, just to reap a couple decades of work out of them. In hindsight that idea seemed possible, but it was labelled stupid quickly after.
One question arose which challenged the probabilities; What if the slaves embraced logic one day? All the power in the world wouldn't be able to stop a hundred-thousand, angry men and women!
The boy would find himself in a dire situation, even if those people simply fist-fought their way towards freedom. Such a degree of risk was immense!
