It makes perfect sense, not the JW way, but the Biblical way. I guess one would question why it took some 5,000 years between Adam falls to Jesus birth for God to do anything? Is God responsible for all the suffering in the world? Did he create evil? No, man created evil. There's a purpose for it all, just because you don't understand it doesn't make it any less true. God has a plan, and He's in control, and guess what? Thing will get even worse before it gets better. But unlike the JW's who believe that salvation comes ONLY via their theological lenses, every man, woman and child who ever lived will live again, because that's what the ransom is all about. Jesus died "a ransom for all".
