The Cult confuses me

I generally understand most of their philosophies, but they seem to contradict. John promotes people saying “YES” and following him. Faith creates the Bliss and manipulates people into constantly using it. Jacob believe the world is weak and his people must be trained. I don’t get how these all work as one. Faith and Jacob are opposites. Faith forces and promotes drug abuse and keeping people hooked. Jacob is almost primal, culling the weak. I feel like Jacob would definitely see the Bliss and it’s addicts as weak. So how does he not just not kill all of them, and why does he allow it in his region. Maybe Joseph has all his heralds turn a blind eye, or his he just openly having ideas in his own cult that don’t work. I understand the main goal, get supplies and make people follow the Father. But is that he and his heralds just don’t care that about all of that, just that they are serving him? I am so confused. Help.
