The nature of the machine universe suggests that God exists as the Maker of the universe. Machines have makers.
Originally, the devil, before he willingly converted himself into a devil, was given much power and beauty, along with a specific job, from God Who created him. Instead of thanking and honoring God, he chose to become a devil.
The devil, before he converted himself was beautiful. So after converting he became ugly I guess? And now he spreads ugliness like he himself has become, right? I'm wondering, when thinking about this devilish being, being ugly and all, if he is not, in the context of your descriptive idea (of the universe as a machine made by God), a spanner in the works? Then according to your description he can't be a spanner in the works. He is an integral gear or something similar. But the gear can change itself, its position, its function? to become something completely different? And now the machine is fu**ed right? Lots of ugly machine parts after that horrific accidental change. And not engineered by the Great Machine Maker right? It was the stupid gear that decided it wanted rather to become a spanner in the works, or not?
While I don't understand what you mean by the wording you use, it is true that the whole universe has become corrupted. In fact, its corruption wasn't just a little corruption off in some insignificant corner. Its corruption is so great that it should have collapsed with a roaring crash, right at the first sin in the Garden.
But, for His own purposes, and for His love of mankind, God has held the universe in place for a time. He has been holding it in place by His strength rather than by the operations of the physics of the universe, which operations have been corrupted by the first sin, and could therefore hold it in place no longer.
God is holding the universe in place for people to be born and live for a time. That time is long enough for them to seek God and be on His side, if they are going to seek Him, that is. God wants people. God wants people to willingly be His people. If they don't want God, they will ultimately lose their life at the end of their eternal stay in Hell.
