When you think of a parent who has a misbehaved child. It is normal as they grow to feel they "know better than their parent. Does a good parent continue to let the child make bad choices and say " since you think you know it all lets just let you continue and see who's right?"
NO they correct them right a way and show them they are young and inexperienced. It is a normal life lesson growing up. So why would a god not do that for Satan, and Adam and Eve. Why would he say " fine Satan, we will let this go on and hurt billions of people for thousands of years just to prove I'm smarter and right."
Does this make sense? Doesn't common sense say that if it was a true story that god would of corrected Satan and Adam and Eve in the beginning of their error just as a parent would. If god's best attribute is love wouldn't love make him fix it then instead of letting harm come to all people for such a long period of time?
