Sure. But I don’t think it matters if you consider Jesus as YHWH or not. Even if you don’t be believe Jesus is YHWH, or even of you think the entire thing is a story myth. It doesn’t matter because you have to at least explain the internal contradiction if you are keen on this theory of OT YHWH = Satan.
Jesus, the good guy, identified himself with the OT YHWH. Whatever your beliefs on the nature of Jesus, it presents a bit of an issue for the theory, eh?
Seems to me if you want to say OT YHWH = Satan, then you at least put Jesus in Satan’s camp.
