These people were desperate, they were being sold as nothing more but replaceable organs, or future prostitutes.
The majority of them were even sold by their relatives or were homeless people who were suffering from hunger and thirst.
Nobody cared about these guys, they were dead people that were still walking around, even worse than zombies because they didn't have even the tiniest shred of freedom.
At least zombies could walk wherever they wished, abide by their free will if they had it that is. But these guys didn't have even that simple thing.
Most of the time they were captured or sold against their wish, and desire, and then were transported, and deal with like they were nothing more but garbage.
Eric's plan was to save them, and give them a chance to forsake weakness and seek strength, an opportunity to leave this behind, and take their fate into their own hands.
