I'm getting tired of this. I've probably told you more in this one thread over the past ten post than you've known of Christianity in the past, and I'm hardly a theologian. I'll answer this one last time, then I'm going to roll my eyes and do something more fun, like get teeth pulled.
Yes, God can do things I can't even imagine. What's your point? Even if he did do this, humanity still would need to pay for it's crimes. Now, the payment for this has already been paid by Christ, but there would still be the need for repenting. If sin was destroyed, we would never recognize our need for Christ, thus damning us all.
