I am inclined to hypothesize that guilt, shame, and badness are emotions which occur as responses instead of the response which, by action or symbolizing, we would otherwise give our felt referent.
The day before yesterday, when Peter's family were having dinner, Father raised an interesting question, "Was there anything in our past that we feel ashamed of, guilty about, or regretted?"
The worry is that those of us who are harder graders than average, if the information were published, would feel guilty and sort of ease up on our grading.
