What is your preferable ending in Saya no Uta?

[kileras1]

I'm making some review and would like to see what kind of ending you think is most preferable by you in Song of Saya in general. There was and old pool at fuwanovel forum, but that's an old one and not many people voted so I wanted something fresh.

WARNING - VOTE POOL CONTAIN SPOILERS DUH!

I seem to remember one going Saya spreading her goodieness making humans monsters which proagonist viewed as humans. Same logic as he saw her as human. And one where she got killed. The third one i just dont remember.
