Is there even such thing as non-religious scrupulosity?

If so, I might have experienced it. Unless I don't actually have a form of OCD. But for me, a scrupulosity lookalike is simply a concern with principles, with being right and good in a more philosophical, secular sense. I'm not concerned about a god punishing me - I'm concerned about being a bad person in the more colloquially moral sense, or being looked down on by better people. Of being "wrong", selfish, unthinking, etc.

Maybe there are other secularists who have experienced this.
