Maybe self-esteem makes sense for deontologists who think that being a good person is a matter of obeying some knowable set of rules, but I think that the goodness of a person is a real number, probably bounded but with no known upper bound. Saying "I'm a good enough person just the way I am; I deserve self-esteem" isn't bad so much as it is meaningless: once you know what you've done and how close the results were to (your current estimate of) what the results should have been, then there's nothing left to describe, no further question to be answered.
