The literature on moral responsibility is ripe with accounts of what it takes for an agent to become blameworthy. By contrast, very little has been written about what it takes for an agent’s blameworthiness to cease or diminish. It seems that there are certain things a wrongdoer can feel or do that might make her less blameworthy than she would otherwise have been. She might experience guilt, atone, apologize, and make reparations. In this chapter, I will argue that prominent accounts of blameworthiness are unable to explain how such actions and emotions can influence one’s blameworthiness. I will then present an alternative account. If we understand blameworthiness in terms of deserved guilt rather than fitting resentment, we can give a plausible account of how blameworthiness can change over time. The fact that a wrongdoer has already experienced guilt, atoned, or apologized will make her less deserving of guilt, and therefore less blameworthy.
