Because she made Jacob a pedophile.
Everyone makes a big fuss over her
Because Jacob is horrible so I wanted to see him suffer when Bella became a vampire!
because technically it is not possible for a male vampire to create a child with a human
because she upstage the lovestory between Edward and Bella and she upstage Edward himself, which is absolutely intolerable.
Nobody else matters just her
Everyone thinks she's so all that and a bag of chips.
