"…Just wait and see how I deal with you!" Jack continued speaking before he rushed towards the doctor who had just gotten to his feet and began pummeling him.
"What are you doing? I'm a doctor!" The doctor was so terrified that he hurriedly shouted at Jack, hoping that Jack would stop beating him. This was completely out of his expectation. He hadn't thought that he would actually suffer a beating in Jack's hands.
Before the doctor could get away, another punch landed on him. At the same time, Jack shouted, "You still f*cking dare to call yourself a doctor? Do you think you deserve that title? I'm going to make sure that you pay for what you have done."
As he said these words, he kept on punching and kicking the doctor. But all the same, he made sure that his punches and kicks weren't that heavy to avoid killing him. What Jack wanted for now was the doctor to suffer great physical pain. Then, he would make sure that his life as a doctor would end.
