He wanted Dean to kill me for one of his stories and Dean refused to, so he got mad and decided to destroy everything and restart the universe.

[ It was, in a general way, a God-shaped temper tantrum. Jack had been willing to die for Dean and he had no intention of fighting him. If that was what Dean needed, even without a soul, Jack knew it was the right thing to do for him. He didn't need a soul to want to do right by his family, despite not having the moral ability to understand the details. ]

I think it was an echo of the story of Isaac and his son. Only he did want me dead. He killed me after Dean wouldn't.

[ With their family, people die all the time and come back, and Jack has the same calm acceptance of it than anyone else. It wasn't the first or last time he died, although it was a particularly painful one. It was too bad, a part of him maybe thought it would be interesting to get to know his grandfather. Unfortunately he was a disappointment just like Lucifer. ]

We had a plan but ... I'm here now. So I can't do it.
