On Keith's death

I've been thinking a lot about Keith. Although he seemed pretty predisposed to being a horrible person, his death speaks to the different levels of horrible that people are capable of being outside of the neighborhoods. Although Keith maims someone will a gun to take their stuff (likely fatally), he comes from a place of wanting to provide for himself and his family. The way that Keith's body is found is to suggest that he pissed off someone who was on a new level of a horrible person. Because of the useless police investigation, I am still left wondering so much about the details of Keith's death and more so why there is a lack of them. Is it at all surprising that Keith was killed the way that he was? Was he destined to reach the level of horrible that drug cartels are capable of? Was he destined to paint his head and light himself on fire? Or, alternatively, was Keith's death a freak accident, and was he onto the right idea about how to make more money for his neighborhood?
