Do tu think Jacob also owes Rosalie o just bella for giving birth to renesmee?

well n a way he doesnt owe her anythng bcuz rose was gunna b selfish and jst take the baby if bella died, and then she tries to eat bella when edward cuts her open to get nessie out.

I guess he does owe Rosalie since she was essentially supporting and enabling Bella's decision to have her baby. It dicho in the book that Esme also supported Bella's decision and that was what swayed Carlisle. Rosalie's protection of Bella showed up some very disturbing stuff though, ie, Edward's willingness to force an abortion on Bella. And the fact that Rosalie had thoughts of keeping the baby herself was wrong of her, I mean Edward would have wanted his daughter.
