QUOTE : Cruelty is especially near the childish character, since the inhibition which restrains the impulse to mastery before it causes pain to others—that is, the capacity for sympathy—develops comparatively late. As we know, a thorough psychological analysis of this impulse has not as yet been successfully accomplished; we may assume that the cruel feelings emanate from the impulse to mastery and appear at a period in the sexual life before the genitals have taken on their later rôle. It then dominates a phase of the sexual life, which we shall later describe as the pregenital organization. Children who are distinguished for evincing especial cruelty to animals and playmates may be justly suspected of intensive and premature sexual activity in the erogenous zones; and in a simultaneous prematurity of all sexual impulses, the erogenous sexual activity surely seems to be primary. The absence of the barrier of sympathy carries with it the danger that the connections between cruelty and the erogenous impulses formed in childhood cannot be broken in later life.
