"Horrible dad" ... but he's not Marie's father, he's Julie's (the modifier "adopted" has no meaning or value in this context; he's as much her father as any biological progenitor).

Was this AITA?

If so, I'd say Julie was the AH a bit for that nonsense about wanting to the first. It's not clear if the sisters have a relationship. I'm guessing not. Either way the gracious thing would be to encourage him to walk Marie first, then Julie. After all, she's getting the big-ass production wedding.

Sorry for the situation, hope he can mend fences with both daughters & their marriages work out.
