Why does someone have to die for Emma to become Dark Swan? She's already fighting the Darkness within, and it appears to be pretty potent stuff. If she feels her family failed her (Including Hook and Regina?), that would probably be enough right there to push her over the edge.

Also, I'm going to be curious WHY Emma sent them and herself back to Storybrooke, and why she felt it necessary to wipe their Memories (Again! Thank you, Snow, for voicing what we were all thinking). Or, DID she send them back. Could it have been Merlin that sent everyone back?
