 The argument for this conclusion assumed from the outset that it is possible to go wrong voluntarily; this was Hippias’ proposal in the case of Odysseus. But Socrates has assumed or stated the contrary elsewhere: no one goes wrong voluntarily (Apology 26a, Protagoras 345e). The argument also assumes that people do good and bad actions on the basis of techne; it is reasonable to suppose that a  techne  that could lead to good actions could also lead to bad ones. But techne can be taught, so that if good and bad action are due to a techne, then people could be taught to act well or poorly. But Socrates does not believe that virtue can be taught (Protagoras 319a–320c). In sum, the awkward conclusion (that it is better to do wrong voluntarily) would follow from premises that Hippias supports, but not from the views Socrates elsewhere affirms.
