"More of them should," Bella says. "Admittedly, I don't know how old the bat lady he's sweet on might be, but she had the chance and didn't take it and anyone he kills after he gets out of the asylum is a predictable result of that choice. He's been trying to get her to kill him the entire time, and he isn't doing it by mocking her ancestry or something, either, he's not innocently radioactive, he goes around murdering people."

Bella doesn't want to be in that room. She might consider it anyway, if it were physical rather than mental damage that had her concerned - because her window into the events in the room is Alice's mind and it's falling asleep. But she's pretty confident that any random physical damage can happen to Alice and he will still come home with her good as new.
