tlahtlacolli = misdeed, error
Burkhart finds the term imperfect for sin, because tlahtlacolli "though used for moral misdeeds, also encompassed a broad range of accidents, crimes and other breakdowns of established order. It failed to convey the sense of personal moral responsibility, with its accompanying burden of guilt, that sin bears in Christian theology."
Louise M. Burkhart, Holy Wednesday: A Nahua Drama from Early Colonial Mexico (Philadelphia: University of Pennsylvania Press, 1996), 170.
