 Critics of the consistency thesis argue that it is too restrictive (Calder 2009, 22–27; Russell 2010, 241). Imagine that Bob loves to torture children and does so frequently, but that Bob also displays genuine compassion for the elderly, perhaps by volunteering at a long-term care facility on a regular basis. According to the consistency thesis, Bob is not an evil person because he does not have evil-making characteristics consistently. And yet most people would want to say that torturing children for fun on a regular basis is enough to make Bob an evil person (Calder 2009, 22–27).
