A terrible tragedy, in our time it is not safe to be anywhere, sometimes it seems that people are becoming more and more cruel. Our society is not perfect, such cases must be eliminated in the bud. The state should take better care of its citizens and isolate normal people from such non-humans. Society creates evil, society must prevent such cases. Strengthening systems that support mental health, education and social services is critical, as well as developing a culture of empathy, understanding and kindness within communities.
