It can be a daunting responsibility for those who are used to the blinders. Suddenly you're responsible for everything instead of just the stuff in that narrow view. Morality? It's no longer assigned to you, you have to figure it out for yourself. Purpose? Again, you can't just take it on faith that there's a plan for you, you have to make your own.

It can be scary stuff for people who prefer the security of being told who they are and what they should do.
