Excuse me? OK, ambiguity. No He NEVER sinned by the letter or the spirit of Torah at the time. In hindsight, anachronistically one can debate that and fail. He just arrogated the Bible. With justification. He took it by the scruff of the C6th BCE neck and dragged it in to service. He was perfect, incidentally, because prince trumps toad. Not because we need God to murder Him instead of us. Coveting doesn’t make you a criminal does it? Or working on the sabbath? So, He celebrated the Passover before the Passover.
