God is not trying to teach us a lesson. That is an incorrect interpretation of the situation. We are getting what we paid for, though. We are the ones who sit by, allowing murderers, rapists, and abusers to grow in our culture. Getting softer on them, blaming their upbringing or their environment, rather than them. Do you know how many children God HAS saved from torture, rape, car accidents or kidnapping? No? Then, you can't really say He doesn't intervene, can you? Oh, sure, we would like Him to intervene whenever we feel it's necessary. But there are repercussions for our rebellion. Sometimes horrible ones. God should shield us from them because why? Because if we had known, maybe we would have obeyed Him in the first place? Too late for that. We were warned these things would happen if we chose our own way. Now, He should just say, "Just kidding"? He's not putting these things on us. They are a natural consequence of deciding for ourselves what is right and wrong.
