Henry Herbert Goddard,
The Criminal Imbecile: An Analysis of Three Remarkable Murder Cases
“ To know the quality of an act of murder is to know that it is unjustifiable; it is to know that it differs from the killing of a rat in that different consequences follow; that human suffering is involved, both that of the victim and of the victim’s friends and associates. It is to know, at least in some vague way, that human society could not exist if murder were the rule. To know the quality of an act of murder is to know enough to be able to distinguish it from justifiable homicide, from killing in war, not to mention more obvious necessary distinctions. ”
