Sam became more and more impressed as he learned about the Dead Clients.
Even in these Dead Clients, there are two sub groups one with the people that owe favors to Leader 3 and come and help him in case of emergencies, but the second group is the most lethal.
These are the people that are targeted by the Black Curtain because of the large sum of money offered by some large organizations. Even if they manage to escape the Black Curtain, they wouldn't be able to live a peaceful life. Simply, put if an organization is super strong but cannot act on the target in the public eye directly and pick Black Curtain to do the job, Leader 3 will go to them, save them create a fake death that is particularly convincing, give them a new identity and finally taking him under him.
Now, Sam understood why there are so many people under Leader 3.
