Richard Loeb is still a little child emotionally, still talking to his teddy bear.... He is infantile. I should say somewhere around four or five years old, perhaps a little older .... Nathan Leopold also is the host of a relatively infantile emotional aspect of his personality but ...he has reacted by a defense mechanism, which has produced the final picture of a marked disordered makeup in the direction of developing feelings of superiority.
