I think Belle.

My reasoning:

Her centric-episode showed us how she was choosing her own memories over Anna's life, aka, Selfishness.

The mirror may have worked on her. Really gotten in her head.

Her many comments about "A hero does this and that.". She wants to be a hero. A lot of heroes make sacrifices...including their lives.

I'm broken record if you're familiar w/ me on here, but I am so hoping for Rumple going hardcore Dark One and I think losing another love of his life will be an added trigger to this finally coming about.

Also, she sucks.
