Martin Luther King Jr establishes two different types of law. One improves the quality of life of those who follow it, and the other harms humiliate, and dehumanize the ones that follow it. MLK says that everyone should respect the first one, if a law is based on good moral principles that elevate everyone, then we must oblige to it, however, if the law is unfair then it is our duty to not respect said law and to do whatever is possible to change it.
