I would rather have people act morally because of empathy and even social pressure, versus “master told me to.”
Granted, if the church and its teachings disappeared today, things may get a bit more rough in the near future. Religion works on some people because they were raised in it and need it to stay normal. But if they weren’t indoctrinated since birth, it would not have such a hold on their morality.
Also granted, I’m sure there are plenty of people who would still act better with it than without it. Just speaking in general terms here.
