You mean when you give them the tools to do better, teach them better and then give them the freedom to be their own person and they go out and live a bad lifestyle that causes them pain and problems?

Can you explain childhood illness? Did the 18 month old do something to deserve cancer that at best requires painful treatments or at worst kills them? Probably the most troubling aspect of the idea of a loving God to me. Not to mention the atrocities that happen to children all over the globe although you can actually blame evil humans for that but it defies logic that an all powerful God lets innocents suffer so horrifically.
