The story tells that the use of force for benevolent purposes is justifiable. It appears rather unkind to use force upon a little child. But the story may be trying to say that it is justifiable to use force for a right cause. Using force to upset or hurt someone is really bad. But if the same force is used for a right purpose, it can be justified. If the child dies of diphtheria, people will not say anything against the dead person. They will blame the doctor. In such a condition the use of force is right.Finally, the doctor’s behavior upset the child for a short time, but its long term effect will certainly be good.
