(c) If a denying fellow-criminal is accused by a confession, the interpretation of the latter becomes difficult. First of all, the pure kernel of the confession must be brought to light, and everything set aside that might serve to free the confessor and involve the other in guilt. This portion of the work is comparatively the easiest, inasmuch as it depends upon the circumstances of the crime. It is more difficult to determine what degree of crime the confessor attached to himself by accusing also the other man, because clearness can be reached in such a case only by working out the situation from beginning to end in two directions; first, by studying it without reference to the fellow-criminal, second, with such reference. The complete elimination of the additional circumstance is exceedingly troublesome because it requires the complete control of the material and because it is always psychologically difficult so to exclude an event already known in its development and inference as to be able to formulate a theory quite without reference to it. If this is really accomplished and some positive fact is established in the self-accusation, the question becomes one of finding the value seen by the confessor in blaming himself together with his fellow. Revenge, hatred, jealousy, envy, anger, suspicion, and other passions will be the forces in which this value will be found. One man brings his ancient comrade into jeopardy in revenge for the latter’s injustice in the division of the booty, or in deliberate anger at the commission of some dangerous stupidity in a burglary. Again, it often happens that he or she, through jealousy, accuses her or him in order that the other may be also imprisoned, and so not become disloyal. Business jealousy, again, is as influential as the attempt to prevent another from disposing of some hidden booty, or from carrying out by himself some robbery planned in partnership. These motives are not always easy to discover but are conceivable. There are also cases, not at all rare, in which the ordinary man is fully lacking in comprehension of “the substitute value,” which makes him confess the complicity of his fellow. I am going to offer just one example, and inasmuch as the persons concerned are long since dead, will, by way of exception, mention their names and the improbability of their stories. In 1879 an old man, Blasius Kern, was found one morning completely snowed over and with a serious wound in the head. There was no possible suspicion of robbery as motive of the murder, inasmuch as the man was on his way home drunk, as usual, and it was supposed that he had fallen down and had smashed his skull. In 1881 a young fellow, Peter Seyfried, came to court and announced that he had been hired by Blasius Kern’s daughter, Julia Hauck, and her husband August Hauck, to kill the old fellow, who had become unendurable through his love of drink and his endless quarrelsomeness; and accordingly he had done the deed.
