William Weldon Billson, Popular Science Monthly (1880)
“ From this single infirmity of the system there must have arisen great numbers of bloody feuds, each having a tendency to propagate itself through generations. It also appears that, even in cases of acknowledged guilt, it was the custom in some communities for the family of an offender to protect him against the avenger, and to resent an attack upon him as an original injury. A family feud must then have inevitably ensued from every wrongful act of violence. ”
