William Carlos Williams -- The Use of Force

In this story we have a man who is two things: A doctor and a private man. The doctor's goals are to help the child overcome an illness, so she can live a healthy life. The private man wants to play, and it is a game of power. He is totally aware of it, yet he is making excuses the whole time, trying to reason what his motives are, and trying to convince himself that his intentions are pure.
In the end he realizes that he is longing for a physical release, that he truly enjoys the fury that was caused by the battle he fought -- against a child.

In my opinion, the story is a summary of nature of man. It is inevitable that any man, no matter what occupation, no matter what religion or ethnicity, has certain needs and certain desires, that he can hardly control, or maybe not at all.
