While Sui-Feng does hate her Bankai, I think she'd hate it more if it were stolen (and clearly it was). Don't get me wrong, I'm well aware of how much she hates it, but despite that, it's still a unique aspect of her own power. It's something that's purely hers which cannot be duplicated or used by someone else.

And then these guys come along and manage to take it away from her. Whatever disgust she has in her Bankai can't feel more repulsive than having a unique part of her power being stolen from her.

Of course, I'm speculating here, but still, in most fictional works, if someone's own unique ability is taken from them, regardless of how much they like it or don't like it, they always feel disturbed when someone has taken it away form them.
