Jacob was getting her wilded up before Bella went in to see Renesmee for the second time AND while she was holding her and he was so pressed up against her like she was a menace to her own daughter, which would infuriate anyone in Bella's situation on those two occurrences.
Or is this question way too ridiculous?

I think he would,because he wanted to kill her before she was born to save Bella...so if she did it on accident. I'm pretty sure in time he'd be fine.

edward would understand, but rosalie would try to kill her probably

wow, i thought everyone would be furious at me for posting this question, because of...well, I'm sort of saying that Bella has the audacity to kill her own child. But I'm glad everyone understands that is so not what I'm trying to do or say about the Cullens :)

ya edward would totally understand i mean he was a newborn once right?

I would think that Edward would actually end up blaming it on himself! Because before she even met Nessie, Edward got way to close to Bella while she was hunting and she almost wanted to hurt him and all the Cullen's even said what were you thinking Edward and he knew he slipped up! So if Edward though she could handle Nessie and she couldn't he would feel really guilty but I think he might would of forgiver her!? IDK ITS A TOUGH QUESTION! But hear hear with Rosalie going nuts lol

i think rose would deal with bella before edward even had a chance

It's a tough question... But it's obvious that Rosalie DEFINITELY won't...
