Everyone can a-b-c this question to death and it will not answer a thing. There is suffering in this world because people introduced it through sin, God allows this suffering to continue to teach us. I know most of you will not believe nor accept this but it is true and I do not think it can be shown to be otherwise.
God loves those who believe and those who do not and the same goes for me, you have no choice in this matter. That puts the matter of total free will to rest.
