If we did not have tragedies like this you can not really appreciate or know the good things about life. you cant have hot with out cold up with out down good with out the evil.. And you are just looking for someone to blame right now. God gave us free will . God had nothing to do with this Humankind created it.
We are close to less than nothing in size on a teeny tiny rock floating in infinite space. No god to care if we live or die. Be nice and eatsome yummy meals and try and laugh a little cause you'll be dead and turn to nothing one day.
