Is Wish Nikki omniscient?

1. She was outside the window when Bear and Ian were on the phone talking about her taking molly and Bear being on some chatgpt ripoff inquiring about molly, and prolly overheard them

2. She probably knew Bear was on the phone again with Ian when Ian told him that the whole "Nikki's dad getting cancer" story was a lie

3. She knew WHERE Sandy was, got her corpse and made a memorial out of it

4. She knew where BEAR AND SARAH WAS and she turned Sarah's face into ground beef

If she really was all-knowing, what does this mean? Is Wish Nikki really loving if she's self-aware that she's a crazy bitch? Does she truly care about Bear's feelings?
