 Sometimes ignorance is used as an excuse for putative evildoing (Jones 1999, 69–70). The argument goes something like this: if an agent has no good reason to believe that she causes significant harm without moral justification, then she is not morally responsible for causing this harm because she has no good reason to act otherwise. For instance, if Dorian shoots a gun into some bushes on a country estate without having any reason to believe that a man is hiding there, he is not morally responsible for harming a man who is hiding there (this case comes from Oscar Wilde’s A Picture of Dorian Gray). In this way ignorance can be a legitimate excuse for causing unjustified harm.
