On the Topic of Antigone vs. Home Fire...

The theme of justice vs. law is portrayed in both Home Fire and Antigone, though the latter is much shorter, and focuses on that theme moreso than the former, which has a variety of themes to explore. That being said, I believe that despite Antigone's focus on the theme of justice vs. law does not lead to a more developed commentary on the theme than in Home Fire. 

Central to the theme of justice vs. law in both narratives is the character in power: Karamat Lone and Creon respectively. These characters symbolize the law, and oppose justice as represented by Aneeka and Antigone. That being said, the characterization of Karamat is far superior to that of Creon; we do not see very much of Karamat in Home Fire, but what little he has goes a long way for his character. 

We see Karamat console Eamonn following his first heartbreak by dropping a massive frozen fish onto Eamonn's bed; this draws the disdain of his wife and daughter, and the action in a vacuum is arguably deplorable, but it is just what Eamonn needed to move on. When Eamonn goes to inform Karamat of his decision to become engaged to Aneeka, Karamat is amicable, and is supportive right up until it is revealed that Aneeka is sister to Parvaiz, who Karamat knows is affiliated with terrorists. Karamat's relationship with his wife and daughter are genuine, and he sees, to some extent, the fault of his decision to keep Parvaiz from being buried in Britain, though he needs a heart-to-heart with his wife to do so. One could argue whether or not Karamat was wrong in preventing Parvaiz from returning with respect to justice, but as a politician, his actions were logical and consistent. 

The biggest component to Karamat embodying the law is that he divorces his identity as an individual from his identity as a politician. This is to the extent that he creates a false persona for Eamonn to give to the media, ignoring the wishes of his wife and Eamonn himself. His personal desires are irrelevant to what he must do as the home secretary, which is why Eamonn accusing him of taking actions based on personal animus so painful and detrimental to Karamat's image.

Creon, on the other hand, is a much more one-dimensional character. The inspiration for Karamat's character seems to more or less draw on a general analysis of Creon rather than specifics. Of the things that Creon disavows, there are three that he regards as absolute evil: anarchy, money, and submission to females. Note that the second of these is never expanded upon outside of passing mentions of "ill-gotten gains," and the third is shown through his attack of Haemon's character.

As a character, Creon never truly undergoes development, which is in stark contrast to Karamat, who changes following his talk with his wife. The parallel to this would be Creon changing his mind following the prediction of the seer, but Creon's decision to free Antigone was not based on a change in is character, but out of fear. Now, fear for Eamonn was a component of Karamat's decision, but he also felt empathy for Aneeka through his own experience with his mother's death. Creon had no empathy for Antigone, he simply feared that he would die a dog's death that the seer predicted, and acted wholly out of self-interest.

Furthermore, Creon does not portray the law to a degree that allows for critical thinking in the way Karamat does; one could even say that Creon is a bit of a strawman. There are several points in Antigone where Creon is shown to act purely out of self-interest, and regards Antigone's disregard for his law to be a personal affront. This stands in stark contrast with Karamat, who removed himself from his position, and solely sought the best interests of the country. Creon, more than embodying the law, embodies a position of power when abused; obviously the law is going to be seen as inferior to justice when it is portrayed through a dictator. Karamat was many things, but he was no dictator, and so the discourse of law vs. justice was more nuanced, the two stood in opposition to one another as concepts on both a national and personal level. Creon allows for none of this nuance, because not only is his character shallow, but the play outright states that his arrogance and laws were inferior to that of gods, of justice. There is no conceivable way to argue for the side of the law when Creon is the one portraying it.

Overall, Home Fire poses a question of whether the law or justice should take precedence over one another on differing scales, and allows for nuanced discourse for either side. Antigone is an overt statement that justice supersedes law, and uses tyranny as an example to do so.
