Beauty & the beast

Today i read an article in about Bhopal gas tragedy....on 2nd December 1984
just bcoz of some once neglegence more than 20,000 people lost their lives in a night just like that. and so many people got injured , some are facing till now. and the main perso behind the owner of this Union Carboid company Waren Anderson is living his own retired life.
who gave him the right to kill so many people. why he and his company dint take such small precautions. why the companie's workers were not aware about such situations?
Are these pople's lifes so cheap that they can die just like that ??????
This article also mentions about 9/11 blasts in Twin towers..... "United States Of America" the most powerful country with new technologies.. but this great country also collapsed after this incident. Some people must have felt really happy because America's nose was down then in front of this horrifying terror...!!
But if we look as a human we all are facing same problems... we the peace lovers..... wont harm anyone until they do.......
so is that senscible that thousands of innocent people were killed by them....
we cant explain terror in bhopal that was also man maade mistake then why do we look at america by piitty...
whtaever happened was worst , we do agree.
and so its our responsibility as a human being to be careful, and we should fight back to these problem which happened in Bhopal or terror attacks in America in 2001 or attacks in Mumbai last year which shattered our lifes.....
I personally think we can fight back but it needs regular and concrete effforts....
