So, basically, if you are an unbeliever ...and you think, "Why, would a loving God allow terrible suffering like we see it in the world?"

The answer is only clear to a believer.   If you are the one who questions God, and why He allows suffering ...He is waiting for you, that's why He is allowing the suffering.

When you convince everyone that you can ...to not believe in Him, for who He is, and most everyone is far removed from accepting Him, then I believe He will end the evil.   

So, to simply answer the question:  God is waiting for you!!
