The old "think of the children" argument. Seems to always get an emotional reaction from someone. Gun violence in the inner cities and we must push gun control because "won't someone think of the children?"
God gave man (Adam and Eve, man meaning mankind) a set of rules to follow. Rule #1) Worship me and praise my name in all that you do. Rule #2) Don't eat from the tree of the knowledge of good and evil. That's it. Simple, right?
Man chose to break the second rule. God did not cause man to sin against Him, man did. Once Adam took a bite from the forbidden fruit, sin entered. And once sin entered, bad things happen, due to that sin.
So bringing up the children and how horrible it is to allow them to suffer in some way, is not a good argument against how God operates.
