@Owyn I dunno, depends on what the motives were in the first place. All we do know so far on that end is the goddess made a suicidal person ridiculously immortal, and the evil god wants nothing to do with her. That's not a lot to go on really. Maybe she'd be perfectly happy to let this world suffer under the fallen heroine.
I'm betting its the Goddess of Fucking Around. Giving a suicidal peson immortality and scaring off an evil death god with just an assumption she may be the cause makes me think this is a trickster goddess who loves to screw around with people.
