Regarding the new Evelynn

first i just must get out of the way that i love everything about this new rework, except that one line regarding amumu, even if he was the last person on earth he still wouldn't make the cut, ouch. Anyways i had two questions on my mind, the first one being whether Evelynn does what she does for pleasure or as nourishment, i would have thought both but some of her lines make it sound as if she does this more for the enjoyment of it than anything else.

the second thing is in the lore it is stated that Eve is a demon using the form of a woman to lure in prey basically a succubs but again some of her lines indicate that there might have been a before for Eve and she wasn't born the way she is. something about being overwhelmed by agony at first and now it being barely enough.
