"What's the worst that can happen?" is a pretty wide open question when you're capable of killing a god and getting reborn a bunch of times.
That said, I'm wondering whether their weird cult is hoping to utilise her in their attempt to become all-powerful (hopefully without getting smacked up by an equally powerful kangaroo).
do you fear death if you know you will be reborn again with all your memories.
Makes you wonder what her non-Saturn incarnations were like as small children.
