The powerful, as Nietzsche points out expressly, have no need to prove their might either to themselves or to others by oppressing or hurting others; if they do hurt others, they do so incidentally in the process of using their power creatively; they hurt others 'without thinking of it'. Only the weak man 'wishes to hurt and to see signs of suffering'. A good illustration of the manner in which the person who has power may hurt another person incidentally without the express wish of doing so would be Goethe, whose loves Nietzsche probably had to learn by heart, like most other students Goethe -- as German teachers like to point out -- broke Friederike's heart by lavishing his love upon her and then not marrying her. Goethe, however, had no thought of seeing the poor girl suffer. Only the weak need to convince themselves and others of their might by inflicting hurt; the truly powerful are not concerned with others but act out of a fullness and overflow.
