A common justification for retributive views of punishment is the idea that injustice is intolerable and must be answered. For instance F. H. Bradley writes:
Why … do I merit punishment? It is because I have been guilty. I have done ‘wrong’… Now the plain man may not know what he means by ‘wrong’, but he is sure that, whatever it is, it ‘ought’ not to exist, that it calls and cries for obliteration; that, if he can remove it, it rests also upon him, and that the destruction of guilt, whatever be the consequences, and even if there be no consequences at all, is still a good in itself; and this, not because a mere negation is a good, but because the denial of wrong is the assertion of right.
A wrong is something that ought not to exist and calls to be obliterated. If anyone is able to remove it, he is obligated to do so or the wrong will also be partly his. To deny or obliterate a wrong is to assert right, Bradley says—as if the two things were counterpoised, one able to cancel the other. It reminds us of the balance held by the figure of Justice, and of debts and credits in accounts. Paying a debt erases it; the debt no longer exists. In a similar way punishment is supposed to erase wrong.
