What is the world coming to...?

You are partly correct that people have lost their sense of humanity. But it is not exactly correct because many persons like you and me suffer severe agonies when they hear such news. You have asked this question this fact itself shows that the news made you restless. I was also deeply shocked when I heard the news. Such incidences are happening mainly because our judicial system is very defective, lingering and even corrupt. The criminals have no fear of law and courts. Our judiciary is sensitive only about the human rights of criminals (who are actually not humans). So firstly Improvement in our judicial system is necessary to prevent such incidences. There are sufficient legal provisions to punish the criminals but their execution is very poor.
