The purpose of criminal law is to forbid and prevent conduct that unjustifiably and inexcusably inflicts or threatens substantial harm to individual or public interests. Feinberg explains the harm principle in following words: 'It is always a good reason in support of penal legislation that it would probably be effective in preventing (eliminating, reducing) harm to persons other than the actor and there is probably no other means that is equally effective at no greater cost to other values'.
