If he thinks he is not violating the laws of Nature, when he wrongs his fellow-men, how is one to argue with the individual who takes away from man all that makes him man?

Context

“{26} Finally, if a man wrongs his neighbour to gain some advantage for himself he must either imagine that he is not acting in defiance of Nature or he must believe that death, poverty, pain, or even the loss of children, kinsmen, or friends, is more to be shunned than an act of injustice against another. If he thinks he is not violating the laws of Nature, when he wrongs his fellow-men, how is one to argue with the individual who takes away from man all that makes him man? But if he belleves that, while such a course should be avoided, the other alternatives are much worse — namely, death, poverty, pain — he is mistaken in thinking that any ills affecting either his person or his property are more serious than those affecting his soul.” source
