Do آپ think Rosalie would have gone back to disliking bella if she'd become a vampire, but Renesmee had died while being born?

No. Simple as that. No.

No because Rosalie is not that mean یا selfish and it wouldn't have been Bella's fault if Renesmee died during the transformation. It's not like Bella would have killed her daughter on purpose.

No. Not at all.

No, definately not.
