Lol, none of them. Let's not play the blame game because it goes around in a circle with it landing on whoever one feels deserve it. You can blame Eva for instilling this ultra-sense of goodness in Snow, but Snow only had it because Cora killed Eva, but that was partially Eva's and her own fault...wait Snow and Charming were doing this because of Maleficent, but that was because of Regina casting the curse, but she got it from Rumple, but Rumple got it from a cave, probably the sorcerer, but Zoso tricked Rumple into becoming the......and it will go on forever.

The only one responsible for Emma's darkness is nurture and nature, but she is a person and she makes her own choices. Not dark heart but potential, which everyone has and how one reacts to it is mostly up to them.
