There’s a fascinating idea that Judas was the one who committed the ultimate sacrifice. That god chose him to be his human incarnate, to truly experience humanity and guilt by committing an ultimate betrayal and becoming the villain of biblical history. All allowing him to finally understand and forgive humanity’s sin, by committing one himself. It follows that this is supposedly maddening knowledge as it breaks the illusion of Christ’s sacrifice.
I’m definitely butchering and ad-libbing the original idea, but I think this makes for a grander story than the traditional “birth myself to sacrifice myself to myself to forgive everyone else” interpretation.
