That's a good question... but why stop there?
What would it cost God to stop a fire where people were killed?
What would it cost God to advise everyone that a tsunami is about to hit so people could leave costal areas?
What would it cost God to stop a 50 car pileup where many were killed or maimed?
What would it cost God to take a drunk driver and sober him up to not kill when he went in the wrong direction on a highway?
Such a tiny thing to do.
But why stop there?
What would it cost God to stop a child from falling out of a window?
What would it cost God to stop a child from falling out of a tree?
What would it cost God to stop a child from playing with a gun and killing a friend?
Such a tiny thing to do.
But why stop there?
What would it cost God to stop someone from breaking a bone during a soccer game?
What would it cost God to stop a child on a bike from falling and scraping a knee?
What would it cost God to stop a child from accidentally breaking the nose of his friend playing with branches and using them as swords?
Such a tiny thing to do...
What would it cost? Not having humans but rather puppets on a string with no will, no purpose and no life.

Yet, Ken, if my memory is not absolutely faulty, you yourself have claimed that God does intervene, and that miracles do occur -- have you not?
And, Ken, knowledge does not make me a puppet on a string with no will, purpose or life. I am as free to ignore the warning of some imminent peril as I am to walk blindly into it. I'll give you an example: I'm a gay man. Many (make it most) of the people that I knew up until the 1980s and 90s are now dead, and I am not. They and I learned about HIV and AIDS at the same time, yet my own choices have left me here to argue with you, and their choices led them to .... well, no more of that.
You -- and most Christians -- believe with perfect faith that God has intervened any number of times in human history, the Creation, the Fall, the Flood, the Exodus, the conquest of Canaan, the impregnation of Mary Jesus. God doing for men what men couldn't do for themselves -- you acknowledge that and don't think it makes them puppets, yet you revert to puppetry at my simple question?
I tell you truly, I think that is equivocal and hypocritical.
