Devastated World

It is not a normal world. I just heard that a parent killed his son only because he was single. It is not normal news and just shocked that society made a lot of jocks about the story. In a country like Iran, most of the people are Muslim and pretending to follow Islam rules, this news is not something that you are ready to hear. 

This parent also killed their daughter 4 years back and nobody noticed. As a human who is leaving in this world, we should try to make it a safer place for everybody. It is not my job to judge but it is society to do a lot of research to find out why we are going in this direction. What is caused and what we really should do for our world?
