Tell that to the blind children who are blind because a parasite lives in the river that they get their drinking water from. I'm sure that they will be happy that they have free will and god is not interfering with their rights. Again, I reinterate, this life is not all there is.

And since you're so concerned for them get your butt away from the computer, buy the medication and get it down there. Or are you waiting for someone else to do it, like God or the government?
We are in a fallen world, crap happens, he does give us guidelines or instructions to live by that will make our lives better and for us to make other lives better. And he will take care of all wickedness in armegedon. He is doing something, what are YOU doing?
