 According to Kant, we have a morally good will only if we choose to perform morally right actions because they are morally right (Kant 1785, 4: 393–4:397; Kant 1793, Bk I). On Kant’s view, anyone who does not have a morally good will has an evil will. There are three grades of evil which can be seen as increasingly more evil stages of corruption in the will. First there is frailty. A person with a frail will attempts to perform morally right actions because these actions are morally right, but she is too weak to follow through with her plans. Instead, she ends up doing wrong due to a weakness of will (Kant 1793, Bk I, 24–25).
