Dean very much did become his Endverse self in a lot of ways, but instead of feeding Cas to the meat grinder to accomplish the desperate mission, he fed it Amara and Jack. (With, honestly, a bit of Cas’s blessing, especially about Amara, and though Cas looked for a different way about Jack, it felt a bit weak in the face of his struggle with Jack’s Big Destiny.)
Even if both regretted it, (“You consumed your sister?” / “Come on, a spell, anything! We’re not giving up on you!”)
It was done.
And it was done so late in the season and without much care, that honestly the series never fully recovered from it.
