How can citizen's responsibilities protect another citizen from human rights violations

"Many of the basic ideas that animated the human rights movement developed in the aftermath of the Second World War and the events of The Holocaust, culminating in the adoption of the Universal Declaration of Human Rights in Paris by the United Nations General Assembly in 1948. Ancient peoples did not have the same modern-day conception of universal human rights. The true forerunner of human rights discourse was the concept of natural rights which appeared as part of the medieval natural law tradition that became prominent during the European Enlightenment with such philosophers as John Locke, Francis Hutcheson, and Jean-Jacques Burlamaqui, and which featured prominently in the political discourse of the American Revolution and the French Revolution. From this foundation, the modern human rights arguments emerged over the latter half of the twentieth century, possibly as a reaction to slavery, torture, genocide, and war crimes, as a realization of inherent human vulnerability and as being a precondition for the possibility of a just society."
