Innocent lives shattered in Connecticut

A few days ago, a terrible tragedy befell a small town in Connecticut, where a deranged person (for lack of a better word) opened fire in an elementary school killing 26 people including 20 kids for no fault of their own. It is one of the worst tragedies that has befallen on a community as far as memory could (although it was the second worse after Virginia one, but here six years and seven years fell victim, shot multiple times). No eyes were dry when it was found out that innocent and small kids fell victim to a random act of a deranged individual who should have known better. In the next few weeks, further details will emerge regarding his motive but for now the lives of the parents affected by this tragedy has been irreparably destroyed forever. Although the suspect's mother was shot to death before this thing happened but my question (and so does millions of people's question) is why kill little kids, what did they do to deserve this kind of atrocity. Now there are so many questions regarding this shooting that people directly and indirectly affected by it will be asking for a long time. I am at a loss of words to describe this tragedy which has really shattered the lives of not only the little victims but also will change how the parents will view the security of their kids and become more paranoid and overly protective (rightly so). After this tragedy, things would not be the same for a very long time for every community in the country.
