Note 555 — Chapter IV
Henry P. (Henry Pomeroy) Horton translation
The obviousness of the reasons which have caused these acts to be classed as crimes is such that it is needless to speak of them. In a society like ours, with its numerous conflicts and its dense population, life would be impossible if the individual were not forbidden to avenge himself personally. Sociology teaches us that vengeance, at first permitted, and even obligatory, has become a prohibited act, because of the great harm it does to society.555
