And part of the Christian "mark" is humility and eschewing self-righteousness and scrupulousity.

So, effective religions have their own internal checks and balances because humans can't hit the mark precisely, by definition, as that would make them into a diety.

Do you mean, that they feel worse about themselves?

That would mean that they are too prideful, probably, and expect superhuman results from a mere human. I suffer from this tyranny of high expectations.
