A breach of faith is something that no person of principles would approve of Betrayal brings out the baseness and meaness of the person indulging in such wickedness. Hence it is universally considered to be unethical and condemnable. However in this particular case where Kemp betrayed Griffin, it would be unfair to cast aspersions on this scientist. Initially when kemp told Griffin that his freedom will be respected his intentions did not appear to be dubious. However when he came down to his study room and read all about him in the newspapers Kemp realized that a villainous person like him was dangerous if allowed to roam around freely. So he wrote a note to Colonel Adye informing him about the presence of a criminal in his house. In the morning when Griffin started giving the details of his life and activities Kemps belief about the evil designs of Griffin was confirmed. Hence he tried to get him captured by employing all the information that he had obtained earlier from Griffin. Keeping in view Griffin’s background and his intentions to let loose reign of terror, Kemp’s supposed betrayal appears to a big service to his fellow men in place of seeming to be a condemnable at. Hence he was very much justified in his breach of faith and he does deserve to be criticized in any way
