There was definitely no initial intention to pen anything about "Black Panther", as it struck me as more or less what you would expect from Marvel, albeit with heavy dosages of black affirmation and women empowerment (though they were satisfactorily done). However upon deeper examination of the dynamics between T'challa and Killmonger, I have been increasingly moved to write something. Spoilers ahead of course.
Both characters have proven to be relatable in their own manner, with valid standpoints. In fact one could postulate that they are two sides of the same coin in relation to the burden of historical baggage. As an audience, I was originally quite upset with Killmonger's death, as it felt as if he was not given opportunity for closure and reconciliation with his family and nation, with the ending seeming like a one-sided politically correct ending with T'challa emerging triumphant.
In other conflict ridden relationships in the Marvel Cinematic Universe, producers have been willing to let things run their course to add value to all characters involved. Thor and Loki's sibling rivalry has moved beyond Greek tragedy cliche, to become more representative of the tongue-in-cheek jousting between siblings in daily life. Captain America's tortured loyalty to his unlucky friend Bucky aka Winter Soldier has even been the center piece theme in Civil War, to get us to question ourselves, and our three way tug of war between professionalism versus past and present relationships. What bugged me was Marvel's stinginess to afford Killmonger time to let things develop and morph between him and T'challa. However upon deeper scrutiny of "reconciliation", especially the final scene between T'challa and Killmonger, I may have to rethink things.
Killmonger had grown up feeling severely displaced, perhaps due to how he esteems his ancestral roots, motivating him to conceptualise his masterplan of igniting civil unrest to all former colonial master nations. After his fatally mortal wound by T'challa, Killmonger is brought by T'challa to his favourite personal spot, with hopes that he finally repents of his ways. And he does. It is only in that spot that Killmonger takes in the full majesty and beauty of his ancestral land, realising he had been too consumed with vindication and hatred, and neglected to appreciate his time there, lest to say assimilate and contribute. It is with this full awareness that Killmonger gets the humble clarity to decline his cousin T'challa's kind offer to preserve his life, taking accountability over the short-lived but grave carnage he inflicted upon his homeland. Death itself being the honourable act of reconciliation and coming to peace, with T'challa giving him a proper Wakandian warrior's burial.
This turn of events is swift and grim, and it is sad to see the character depart. However the convincing reconciliation's speed of a panther's sprint, makes this character's arc of development and dynamics with others extremely commendable, distinguishing it from all of other Marvel's conflicted relationships. After all quality need not be tied to the bondage of time.
