I have to say that your question is not too clear at all. What specifically are you trying to prove in your argument? That of course will impact the answer to this question a great deal. However, just considering the story generally, it appears you are trying to find a similar career or situation that can be related to the events narrated in this excellent short story. "The Use of Force" concerns the conflict between a doctor and a young girl, on whom the doctor needs to perform a throat culture to see what illness she has. As the girl refuses to have this process carried out on her, the doctor is forced to violently subdue her and to force her to open her mouth so that he can find out the information he needs. What is ambiguous about this process is that, although on the one hand he needs to carry out this test for the public good, on the other hand he also recognises that he delights in the struggle and the physical violence he is able to carry out on the girl.
I wonder if we could find a comparison with any job which involves acts that are unfortunately necessary for the greater good but involve pain and suffering for the person concerned. For example, for me as a teacher, part of my job is grading and giving bad news to both students and parents about the progress of students and their work. This has at points been damaging because students and parents have had to change their hopes for that student and what he or she can achieve and do in life partly as a result of what I have to say. This is an important aspect of the teacher's job, because it would not be fair on the student or the parents to let them continue to believe that the student is capable of doing or studying something that is clearly impossible. However, the difference is that I do not enjoy or take a fierce delight in this act, as the doctor did.
