They allegedly get judged.
We're where we are today not due to one ideology. It's the result of contributions from all over. I do find it more ambiguous to credit religion with any of it. I think that's too subjective, honestly.
I'm of the opinion that religion is toxic for humanity. We'd be better off without it. I think a lot people's passion for it was manufactured for them by their upbringing. It's all they know, it's all their friends know. They're sheltered and their world-view was painted for them, long before they had the critical thinking skills to choose it alone. Many of those same people think they can objectively scrutinize it, but I believe that the vast majority are incabable. It I could sum it up in 5 words or less... Religion is a thief.
As an example... I was signed up for something I do not endorse. I had no options. I would have rather been raised on earthly knowledge... Astronomy, geology, human history, evolution... But nope, I was raised to believe in magic. It provided all the "answers."
I was raised in a Bible believing home as well. I walked away. I re-evaluated later, realized many of my beliefs from childhood were wrong, and am now a Christian. I'd like to think I can objectively scrutinize my beliefs.
As far as your point, and religion as a "control"...
I think it's most certainly valid, and true. There are, always have been, and always will be people who either lack the ability or the desire to decide for themselves what their beliefs about the world will be. Those people will follow some established religion. Whether that is christianity, islam, science, or one of countless others, will most likely be based on their childhood experiences.
