Alicia is Best Girl. And most relatable character besides.
Would be a shame to lose her, but as she wants to self-terminate it would be wrong to stop her. And death would be preferable to slavery or brainwashing, as they did with Krum.
Still, it is unfortunate she can't just kill everyone else instead. I can't agree with her seeing the demonfolk as any better... but absolutely agree with humans being trash to be thrown away.
