Explain this world to me

What is going on? What's going on in this world...why are there so much violence, why are there so much hurt....i haf juz viewed powerpoint slides on the recent terrorist attack at Russia...boy haf i missed a lot...i am not e kind who reali reads or watches the news....but i thank those who forward current affairs emails and this one truly opened my eyes. i could practically feel my heart squeezed as i see the pictures of children, yes naked CHILDREN scattered all over the ground covered in blood.why aim at innocent lives, my goodness...truli it ripped my heart seeing the terrified faces of those who survived....

for those who perished in the event, my sorriest condolences to their families....and for those who barely survived, may u find strength and courage to live on.
