...for on the contrary, this is the perfection of the creation according to the underlying intention – to reveal the supreme unity of God, blessed be He. For the entire purpose was to demonstrate His true perfection by first showing exactly what the deficiencies are, so that through seeing their very power we may understand the nature of His true perfection, in that it removes these deficiencies. If there were to be nothing left in the very end to show what it was that had been deficient, what would have been gained from the entire existence of the world?
The perfection would go back to what it was at first (had there been no evil) – His intrinsic perfection alone, for He is perfect – but this would not enable us to discern the real truth of this perfection as we should, through seeing its power to rectify the deficiencies. (The fact that the garments remain as the cause of evil is called a deficiency, but the fact that His perfection does not permit the evil to develop reveals the superiority of that perfection.)
