This movie is a lot deeper than most of you understand
This is a story about personal demons.
We see the movie essentially thru the eyes of the white nurse as she watches the transformation of Moses. She is the audience. What she first sees is these "thugs". They are faceless, nameless, the terror of the night in this area. They are what the media talks about, the bad guys, and yes, they do bad. The white nurse fears them and gives up her loot.
But as time goes on we get to know them and see they are actually kids. Normal kids, even. They like video games (Fifa!)and are goofy. They seem to come from broken homes. They seem to also be kind of expected to live that life. They also arent murderers, just punk stick up artists. The nurse gets to know them, learns their names and sees them as regular human beings, which they are.
As we continue, we hear Moses talk about how how those demons must have come from police sent to kill black boys. He shows an awareness of society and understands his place to be at the bottom of it. But he is still not fully aware, so the demons continue to haunt him.
Later, Moses finally realizes personal responsibility. The girl he likes has his ear, and tells him that everyone he touches goes bad. That is when it hits him that he is the problem. His actions are the problem. He HAS to take responsibility for his own actions. But how? Sadly tho, he can seem to only do this once all his black friends are gone and its only him and the white people. From this new support group he find out his scent is the issue from the blood, and he then forges a plan to destroy his demons forever. He has a plan.
The nurse then goes thru his house and we see thru her that Moses is just a fifteen year old kid. He has silly race car stuff, kid stuff, he is REALLY just a kid. Living on his own essentially as the elder in his household is barely there. She is dumbfounded. It is an interesting moment when she says he looks much older. He has had to grow up quickly in this environment and do what he could to survive.
After that he finally gets rid his own personal demons, literally exorcising them from his home and destroying his old place with them, he is able to move on away from the block. Yes he get punished for his past sins, but thats just fine by him. He has grown from his experience and is making steps towards being a man. Additionally the white nurse (the audience still) understands his plight a bit more, and even admires him for how he has had to cope all this time. There is empathy here by the white nurse to understand his struggle. We see when Moses gets his chance that is a leader, a man of principle and finally personally responsible.
