  Some utilitarians respond by arguing that we really are morally required to change our lives so as to do a lot more to increase overall utility (see Kagan 1989, P. Singer 1993, and Unger 1996). Such hard-liners claim that most of what most people do is morally wrong, because most people rarely maximize utility. Some such wrongdoing might be blameless when agents act from innocent or even desirable motives, but it is still supposed to be moral wrongdoing. Opponents of utilitarianism find this claim implausible, but it is not obvious that their counter-utilitarian intuitions are reliable or well-grounded (Murphy 2000, chs. 1–4; cf. Mulgan 2001, Singer 2005, Greene 2013).
