"My belief is that, morally, God and Satan are vaguely on the..." — Criss Jami quote meaning

My belief is that, morally, God and Satan are vaguely on the same page. According to the common understanding of Satan's origins, 'holiness' is, metaphorically, frozen stiff in his veins: and at that a corrupted formula - i.e. legalism. The vital difference is that God is willing to offer grace for our sins; he delights in grace. God is the one and only holy and just punisher of sin, yes, but that is partly so because punishment for the sake of punishment is not something he loves. Whereas Satan, as the accuser, and as it is written, actually seeks God's permission to punish; he, being a seasoned legalist, delights in finding wrongs and will defy his own morality just to expose immorality. This is why both the anti-religious soul and the violently religious soul are, whether consciously or unconsciously, and sadly enough, glorifying their biggest hater: Satan is not only a lawless lover of punishing lawlessness, but also the sharpest theologian of us all. He loves wickedness, but only because he loves punishing wickedness.
