Snow made Regina split Snow's heart in half to sustain Charming after he'd been Dark Curse'd, while Regina wanted Frankenstein to revive Daniel and used Dark Swan to keep Robin alive. They are different. Emma turned Hook into the very thing he hates (and it was against his wishes). That will risk the lives of others (like Rumple).

Snow and Charming is different. Snow was right about one thing. There hearts are as one, and it worked. And ever since Snow was poisoned by the poison apple, Charming acted as though he feels her pain inside him and can tell Regina did something terrible to her. Snowing is gifted. And they didn't risk the lives of others for that.

Regina begged Emma to help Robin, and Emma did it by choice. She didn't anyone else's lives (excluding Robin's and hers during the fury incident).

So clearly Emma's actions and mistake would cause consequences.
