The Eyn Sof, blessed be He, wanted to bestow complete good, so that its recipients will not even be ashamed. He planned and calculated how to reveal His perfect oneness in actuality, for before Him there are no barriers or deficiencies. Accordingly, He established the system of government that He follows, in which eventually evil actually turns back into good. Initially, He gave a place for evil to do what is in its power, but at the end of everything, all the damage is repaired and all evil turns back into actual good. And thus His oneness is revealed, and this itself is the delight of the souls.
