No one knows what the future holds. He may have spared these folks from any of a number of evils by bringing them home to Him. He knows what He is doing.
No God did not "Bring them home!"
We all suffer at some point in time because of the rebellion in the Garden.
What God did is to give man Free Will and the Right to be more than puppets!
(Read the book of Job which gives the answer to this very question)
Job, the Apostles, Jesus ....
As written: “The whole world is lying in the power of the wicked one.” (1 John 5:19)
This world reflects the personality of the invisible spirit creature who is “misleading the entire inhabited earth.” (Revelation 12:9)
Satan is hateful, deceptive, and cruel.
So the world, under his influence, is full of hatred, deceit, and cruelty.
That is one reason why there is so much suffering.
Another reason for suffering is
“time and unexpected events.”(Ecclesiastes 4:1; 8:9)
I have seen something further under the sun, that the swift do not always win the race, nor do the mighty win the battle nor do the wise always have the food, nor do the intelligent always have the riches, nor do those with knowledge always have success,
because time and unexpected events overtake them all.
