Remus/Ruby
As for the bounding by the moon, it's hard to say. I never tried not turning. I either had a magic cloak that kept me from turning, or I did it anyway.
As for the hunting down humans, I can say that I never once wanted to hurt someone.
But the story of that was under different circumstances. For the first 20 sum years of my life, my grandmother never told me. She said the cloak I wore scared off wolves. Her lie resulted in me hurting someone I cared about.
That happened before I was taught how to control myself.
