Is it natural justice?

Dear Sir,

Again in America, a teenager killed his parents and 28 others our of which 20 children and 8 adults.  This is all happened on 14^th Day of December 2012, but this is not single incidence of firing in America but it is the 9^th incident of firing by the teenager.  Interestingly in all incidents the culprits are the below 18 years, except the incident of October 2, 2006 in which Charles Robert IV 32, went to the school and took 11 girls hostage 5 were killed and 6 wounded.    

21^st Day of May 1998 first case of firing was reported when 15 year old teenage Kip Kinkel killed his parents and killed two students of his school.  Is it related to anywhere with psychomenia, if it is so then what is the reason behind.  Is it natural justice, why American teenagers are becoming crazy?  I am sure this is the natural justice to US citizens.  Who are becoming mad and their own generation killing their own people?  Whatever US forces did with the innocent citizens of Iraq, Afghanistan teenagers were killed for no fault.  Anybody who believes on single supreme power, they will have to believe that almighty listen to every innocent and he is taking revenge in his own way.  In 2003 America attacked on Iraq for no reason, because first gulf war had come to a conclusion and Kuwait was liberated from Iraq possession, but second gulf war was the monopoly of America for that she is repenting in form of firing by her own citizens.  The sins committed by the George W. Bush senior and junior have come in the form of  nightmare for the citizens of America.   This is 9^th case of firing in US after 1998.   In firing so far more than 100 US citizens have lost their life.

American teenagers are becoming crazy and they are killing to their own citizens.  If America will not stop Drone attack on Afghanistan, Pakistan and pulling down its Army from the Persian Gulf and Afghanistan then that day is not much far when civil war will erupted in America and its existence would be in jeopardy same in case of Soviet Union.

Thanking you,
