I remember that scene where she told Narcissa she'd give her sons gladly to the Dark Lord if she had them. I don't know, she's a mad woman, but I was under the impression that she wanted to have children so I voted that she couldn't. I mean, what's the point of marrying a man you don't love (Rodolphus) if you're not going to have children....I think the whole point of those arranged pureblood marriages was to ensure that little pureblood Lestranges, Blacks and Malfoy will be running around...

she never wanted kids-not to love them as a mom should anywayz

Only Voldemort's.

I actually heard somewhere that Rowling said Bellatrix can't have kids. I don't think it's true but you never know.

J.K. said Bellatrix didn't want children.

When?! I wanna see/read the interview!

Yes but with only with VOLDEMORT

^ that's true

They'd just get in the way of being a Death Eater.
