The Blue Fairy is driven by morality and duty.

Her giving Baelfire the bean was her attempt at freeing Rumpelstiltskin from his curse without killing him and preventing him from giving Baelfire a bad environment to grow up in. This may also be because she has seen multiple Dark Ones and what their curse as done to them and wanted to break the cycle.

Also, her antagonism to Rumpelstiltskin may have been triggered by his own hostility and her own annoyance/hostility ended up affecting her words ("You drove him away").

When it comes to Nova and Grumpy, this is where the duty part comes in. Basically she follows the whole 'business before pleasure idea' and believes that their duty as fairies comes first and that having a romance would distract a fairy from her duties and affect her actions because love can cause a person to do things they normally wouldn't (e.g. Regina's love for Daniel in combination with Snow White's 'betrayal' and her inability to hold Cora at fault ended up causing her to go down the road to darkness and vengeance) and she also wanted to prevent her younger fairies from experiencing heartbreak.

So what I'm trying to say basically is that she's good, but her morals/values affect her actions in ways that make her seem bad.
