"When one individual inflicts bodily injury upon another, such injury that death results, we call that deed manslaughter; when the assailant knew in advance that the injury would be fatal, we call this deed murder.
But when society places hundreds of proletarians in such a position that they inevitably meet a too early and an unnatural death, one which is quite as much a death by violence as that by the sword or the bullet; when it deprives thousands of the necessaries of life, places them under conditions in which they cannot live - forces them ... to remain in such conditions until that death ensues which is the inevitable consequence - knows that these thousands of victims must perish, and yet permits these conditions to remain, its deed is murder just as surely as the deed of the single individual ..."
