In his 1963 essay ‘Supererogation and Offence: A Conceptual Scheme for Ethics,’ Roderick Chisholm describes a category of human acts which he calls ‘offences’:A system of moral concepts which provides a place for what is good but not obligatory, should also provide a place for what is bad but not forbidden. For if there is such a thing as “non-obligatory well-doing” then it is plausible to suppose that there is also such a thing as “permissive ill-doing.” There is no term (...) in moral literature, so far as I know, which has been used to designate just this latter class of actions; I shall refer to them as “offences.”Some recognize the possibility of acts, commonly called acts of supererogation, which are morally good or praiseworthy but not obligatory to perform. In this passage, as well as in a later article co-authored with Ernest Sosa, Chisholm calls attention to the possibility of acts which are morally bad or blameworthy to perform, but whose performance is nevertheless not forbidden.

Ethical notions such as good and bad, are often treated as though they were ?symmetric? in the sense of having the same moral ?weight?, one in a positive the other in a negative sense. I argue that they are in fact ?asymmetric? and that the negative members of such pairs of notions are more fundamental and definite, logically speaking, and operationally more important than the positive members. Detailed arguments are given to show this for some non?moral notions, such as life (...) and death, health and illness; some semi?moral notions such as pleasure and pain; and finally for the moral notions of happiness, benevolence, right, and good and their negative counterparts. One of the intentions of the article is to show that a systematic view of such asymmetries may have consequences for one's view of the proper or desirable structure of a general theory of ethics: norms stating prohibitions and norms stating permissions will be seen to be, in a sense defined in the text, more fundamental and important than norms stating ('positive') obligations.

The possibility of supererogation--doing more than one feels morally obliged to do--is denied by many thinkers.
