Benefiting and hurting others are ways of exercising one's power upon others; that is all one desires in such cases. One hurts those whom one wants to feel one's power, for pain is a much more efficient means to that end than pleasure; pain always raises the question about its origin while pleasure is inclined to stop with itself without looking back. We benefit and show benevolence to those who are already dependent on us in some way (which means that they are used to thinking of us as causes); we want to increase their power because in that way we increase ours, or we want to show them how advantageous it is to be in our power; that way they will become more satisfied with their condition and more hostile to and willing to fight against the enemies of our power.
