The antagonism of justice and injustice is very important in terms of understanding of social justice and equality. In this respect, King’s idea that injustice anywhere is a threat to justice everywhere is absolutely correct. In fact, it is impossible to build up a just society if there is at least one person who is oppressed or discriminated, i.e. who suffers from injustice. In this respect, it is likely that the unjust practice being once applied to an individual will spread soon on other individuals. For instance, a person, who has committed a crime and escaped arrest, feels his or her ability to escape the punishment and commits new crimes to get easy money as long as he or she is not arrested and punished and, thus, the justice is reestablished. Furthermore, the ignorance of injustice provokes the tolerance of the entire society to injustice, because people start to perceive injustice as a norm. They believe that if injustice happens than it is normal. No wonder, many people believe that they cannot change the existing unjust practices because there is the social system, the state that sets the rules, which cannot be violated, even if they are unjust. Finally, when people witness injustice they often think that this will never happen to them. For instance, an individual can witness that his or her colleague is fired without any reason but he or she does not attempt to protect the fired colleague or, at least, protest against such actions of the employer, because he or she believes that he or she will not be fired. However, when he or she is fired there is no one to protest and support him or her, while employers easily fires employees if it is necessary to save costs and if there is no resistance from the part of employees.
