Fear in religion

I’ve looked into some other religions and from what it seems it seems like fear is the foundation/root of belief. What I mean is saying “you will get punished if you don’t do X thing” that may just be for personal benefit. This can be used to exploit others, get money etc etc. From what I understand historically this was also a big thing in religions like Christianity where it seemed people were indoctrinated and a system was in place that used fear to “put people in their places” and there were things like tithes. Is this the same case with Islam? Even if money isn’t necessarily in the equation it seems fear is the root to belief in anything, it’s also seems to me to be the reason why people don’t branch out and stick to their own religion without questioning anything, I think this ties into something called confirmation bias too. It seems people are just devoid of skepticism and taught something at birth and roll with it fearing if they don’t there will be consequences and that’s a pretty dangerous train of thought.
