It also happened in the season 4 finale

One of the dwarves dies right after Evil Snow ripped out his heart (and before she actually crushed it)

You can see it here https://www.youtube.com/watch?v=tkMBBDm2VNI

One might think they used the heart to control the owner (like Regina did with Graham) and told them to die.

In case of Regina, she prob did it because she didn't want to see her father in pain

Evil Snow.... well, I don't know.
