Albert Moll, The Sexual Life of the Child — Pathology (1913)
“ The tendency to cruelty appears in early childhood, and it is only subsequently that this tendency becomes definitely associated with the sexual life. But even though this association (of cruelty with the sexual life) is demonstrable in so many instances, we are not for this reason justified in regarding every brutal act, all deliberate cruelty, as manifestations of sadism; and this reservation applies no less to adults than to children. Thus, delight in the sufferings of others, though it may be regarded as analogous with sadism, has no necessary connexion with the sexual impulse. ”
