I think it wanted to show that racism can lead to violence and even murder.The movie is about racism and violence and how it can destroy someone's life.I don't remember how the main personages were names,saw it a long time ago,but the older brother was jailed,and the younger one killed.A way to say that the first one almost destroyed his life,and the last one lost it.  The end......I think it wanted to show that violence and racism can harm anyone,and in a way that the action didn't end there. You're right Miss Romania, racism can lead to violence and murder. Some poor, innocent White person gets killed, beaten or raped by Blacks and Browns everyday in America just for being White. There are many neighborhoods in the USA that a White person cannot walk through without being killed or assaulted.
