 Analogous to the common thought that the punishment must fit the crime, it is plausible to suppose that the blame must, in some sense, fit the transgression. Perhaps it’s legitimate to be annoyed at your friend for forgetting your birthday one year, but you shouldn’t (at least in the absence of some special context) vow never to speak to them again as a result of that one lapse. What will count as a proportional blaming response to a transgression will no doubt vary with different relationships and different transgressions, but there will likely always be some responses that take the transgression too seriously, and some that don’t take it seriously enough.
