It REALLY is up to her, so if she wants to be induced, you have to just be there to support her. Nothing's worse than being harassed/guilted/etc when you're already vulnerable.
Thaaat being said, I agree with you. I'd personally avoid induction at all costs. There are loads of things you can try if she wants to help to start labor along (walking, LOTS of walking, rocking on an exercise ball, etc.), but the baby will come when he/she is ready!
