Asymmetries need not be deontological; they could be axiological. A pure consequentialist could maintain that negative experiences are lexically worse than absence of good experiences, all else equal (in particular, controlling for the effects of good experiences on the prevalence of negative experiences). This is controversial, to be sure, but not inconsistent with consequentialism and hence not vulnerable to Will’s argument.
