I don’t quite understand what you mean in that first paragraph. Are you talking about people who justify clearly bad behavior with religion? Or the opposite, people who are uncertain about good behavior because it contradicts their religion? Or both at the same time, people who give up trying to define good and bad and just do whatever, because God will forgive them anyway?

I worry about being good though, not for spiritual reasons, but because the world is created by the tiny choices we make each day and I worry about making the world worse out of complacency.
