In the context of "Man Without a Country" by Edward Everett Hale (not Walter Hacket), a significant theme related to justice is:
C) Justice can be manipulated by those in power to wrongfully punish.
The story illustrates how the protagonist, Philip Nolan, is unjustly punished for his actions. His punishment reflects how those in power can wield justice as a means of control and retribution, even when it results in wrongful consequences for individuals.
