In Hans Christian Andersen's story she isn't really either. it's a troll that has the mirror that shatters and distorts what Kai sees (the mirror splinters also get into his heart - freezing it), and it's Gerda who brings Kai back. The snow queen just takes him to her palace (the only thing he finds beautiful are the "snow bees" -snowflakes).

from the plot on the wiki, it really seems like the snow queen is holding Kai captive to help him. This is why the film Frozen changed her from being the anatagonist (as they intended) to a misunderstood character. iI must read the actual story soon.
