The Book of the Dead has the deceased recite this to the god Osiris:

Behold, I have come to thee, and I have brought maat (i.e., truth, integrity) to thee.
I have destroyed sin for thee.
I have not sinned against men.
I have not oppressed my kinsfolk.
I have done no wrong in the place of truth.
I have not known worthless folk.
I have not wrought evil.
I have not defrauded the oppressed one of his goods.
I have not done the things that the gods abominate.
I have not vilified a servant to his master.
I have not caused pain.
I have not let any man hunger.
I have made no one to weep.
I have not committed murder.
I have not commanded any to commit murder for me.
I have inflicted pain on no man.
I have not defrauded the temples of their oblations.
I have not purloined the cakes of the gods.
I have not stolen the offerings to the spirits (i.e., the dead).
I have not committed fornication.
I have not polluted myself in the holy places of the god of my city.
I have not diminished from the bushel.
I did not take from or add to the acre-measure.
I did not encroach on the fields of others.
I have not added to the weights of the scales.
I have not misread the pointer of the scales.
I have not taken milk from the mouths of children.
I have not driven cattle from their pastures.
I have not snared the birds of the gods.
I have not caught fish with fish of their kind.
I have not stopped water when it should flow.
I have not cut the dam of a canal.
I have not extinguished a fire when it should burn.
I have not altered the times of the chosen meat offerings.
I have not turned away the cattle intended for offerings.
I have not repulsed the god at his appearances.
I am pure.
I am pure.
I am pure.
I am pure....

For most of them, no problem, but I know I would have trouble with a few of these should I find myself in a situation calling for my own personal confession (perhaps an exchange program between adherents of the Egyptian and Christian creeds). "I have not caused pain." "I have made no one to weep." You mean like in my entire life? Even when I used to teach physics?

I imagine Osiris seated on a high seat, not saying anything. Over the long millennia he has heard every attempt to weasel out of this list of basic acts of decency and restraint. I don't imagine that citing the rigors of science would change his demeanor at all, not even if I could recall the special circumstances and extenuating factors involved (he was an engineering student who had no business in engineering, she was a pre-med with an air of entitlement, etc.), an effort which probably would result in more fiction than fact. Perhaps the look of misery on my face would communicate to the god the difficulty we living mortal beings have in avoiding any sort of questionable action or inaction somewhere along the way. And if the fishing one and the worthless folk one are deal breakers, then what hope can I have?

That the merciful judge in the halls of the dead grades on a curve, that's what.
