So yes, most religions if not all are based on unscientific claims, but they make people's lives better.

I think the underlying issue is whether a person views the objective appraisal of reality as a positive thing or not. For someone who doesn’t, self-deception may seem the better choice.
I'm not religious, but that doesn't make any sense: those cases would weaken the correlation (or correlate it the other way), and now you're also claiming a causative effect that's opposite to the correlation you don't refute?
When we live in a society which publicly announce anyone doubting the dogma is a miscreant who should be tortured through long painful experiments, we will feel safer and better if we are in the camp of the true-sincere-believers™. Indeed it’s far less likely that any of these corrupted souls will come and trouble our peaceful minds. But if we have a ounce of skepticism in our veins, there’s no happy path for us in this society.
The reason those studies are just correlational, is because in social sciences, you don't really have many other tools.
There are no axioms, deduction is impossible. So that part of the argument is not really all that much valid. You have no mechanism to make social sciences more exact.

Yes, there are also negative outcomes. But positive ones are stronger than the negative ones.
And also, some of your examples are not negative at all. The point of fear of damnation for example is the reason why ethics were enforceable for hundreds or thousands of years, when the state was significantly weaker, there weren't real courts, etc. Shame and guilt are important motivators. They developed in humans to make correction of antisocial behaviors possible if you don't want just violently punish people for everything. Having no shame and guilt is an attribute of psychopaths.
The Taliban shows it is not always thus. Nothing is that simple.
I think, when we look at all social phenomenons, we need to look on the whole system. What is the role of religion? When religion is not there, what fits the hole? (Nowadays, there are many non-religion religions like consumerism, extreme-individualism, or global warming; all of those have their own prophets, the story of fight between good and evil, rituals, inherent sin and a way to 'buy out' out of that sin)
You would expect a population with "better lives" to outperform the rest.
