God does not need to destroy us. He made this universe and Natures laws that govern it. In any self-correcting system when the laws are not followed consequences ensue automatically. So, God does not actively respond to our behaviors with extra effort on His part when we don't follow the rules. The consequences are written directly into the way Nature works.

If it was man made it can be man re-made.
