Thieves, robbers, murderers and cheats, who commit crimes recognized by themselves and everyone else as evil, serve as an example of what ought not to be done, and deter others from similar crimes. But those who commit the same thefts, robberies, murders, and other crimes disguising them under all kinds of religious or scientific or humanitarian justifications, as all landowners, merchants, manufacturers, and government officials do, provoke others to imitation, and so do harm not only to those who are directly the victims of their crimes, but to thousands and millions of men whom they corrupt by obliterating their sense of the distinction between right and wrong.
