 Critics have charged that hybrid accounts are ad hoc or internally inconsistent (see Kaufman 2008: 45-49). In addition, retributivists argue that hybrid views that integrate consequentialist rationales with retributivist side-constraints thereby relegate retributivism to a merely subsidiary role, when in fact giving offenders their just deserts is a (or the) central rationale for punishment (see Wood 2002: 303).
