Many now accept that Frankfurt-style cases refute the principle of alternative possibilities (PAP). But, in this paper I argue that even if Frankfurt-style cases refute PAP they do not refute a related principle: the principle of avoidable blame (PAB). My argument develops from the observation that an agent in a Frankfurt-style case can be aware of the nature of their situation without this undermining their moral responsibility. I then argue that PAB captures all that is important about PAP such that the refutation of PAP is of no concern as long as PAB survives.

Cases involving certain kinds of manipulation seem to challenge compatibilism about responsibility-grounding free will. To deal with such cases many compatibilists give what has become known as a ‘soft line’ reply. In this paper I present a challenge to the soft line reply. I argue that any relevant case involving manipulation—and to which a compatibilist might wish to give a soft line reply—can be transformed into one supporting a degree of moral responsibility through the addition of libertarian elements (such as alternative possibilities of a kind unavailable under determinism and executive control of the sort commonly associated with agent-causation). From a compatibilist’s perspective the subtraction of libertarian elements should make no difference to any assessment of the agent’s responsibility. The compatibilist should therefore judge the agent morally responsible after the removal of the libertarian elements. Yet removal of the libertarian elements returns the case to its original form and thus what started out as a soft line has now collapsed into a hard line reply. Various ways of resisting my argument are considered, but each is shown to carry important burdens
