There's plenty of my world's vampire's you'd probably not want hanging around too long if they fell from the sky and all. Bloody insane, a good lot of them. My lot loses their soul when they're turned, gets replaced with a demon soul. My case, I won me a shiny new soul, humanity in tact. Not that it was easy, mind you, but I got it all the same. Honestly? I'll just leave this here for you, mate. Never thought that fictional thing would come in handy. Huh.
But yeah, to answer that question, reformed is a good word for it.
