This is a tragic story but it's also what happens in third-world countries where you pull a truck off the side of the road to sell fuel to citizens.  The world is an absolutely enormous place--beyond comprehension.  And death, suffering, and tragedy occur all the time.  I'm not going to worry about the lives of a handful of random people who I didn't know existed until I knew they no longer existed.  These people might as well be fictional characters to me.  Sure, someone is grieving them somewhere.  And this event probably really did happen.  But to me it's not real and it truly doesn't matter.  And, frankly, despite this modern age's attempt to argue the opposite, I don't think the world is any better a place because I know these people are dead.
