What do you think was the author's purpose for writing this

I think this story points out the political abuse that can be inflicted on the vulnerable in a capitalist society. El Patron clones himself so that he can live forever by harvesting the organs of people whom he views as less than human. This is a metaphor for his parasitic, cannibalistic nature, and from this arrogance his policy can be seen as abusive. He leads an oppressive regime, imposing his authority by fear and domination. He is clearly only interested in what is best for himself, and in the end he proves to be a sociopathic murderer.
