14 could-be-Spoiler questions i have.

I've only watched the Anime (once when released, and again a few days ago), but i've heard some spoilers so i have some questions. (Also, i'm not that smart, so the going back and forth in the timeline or whatever left me with some questions.)

I'm going to refer MC as kumoko most of the time. And i might spell it wrong.

Please spoil me for whatever is more popular (LN/WN)

  1. The elf teacher's ability tells her where/how students are, so why does she tell the "new" hero and dragon girl, that kumoko is dead?
  2. When old hero and Saint kill that "special" spider, that spider is afraid of demon king, with kumoko next to her, that spider was actually kumoko's kid (from spider egg lay ability) right?
  3. Anytime we see kumoko in labyrinth, it's 15 years ago? But when we see demon lord with kumoko, that's future? (Since she's full body kumoko), and is half-spider/half-human supposed to represent the present?)
  4. FEI says heros party did a lot of damage to demon lord, but it was kumoko who killed hero right?
  5. Kumoko sides with demon lord because taboo 10 shows her the world is gonna end?
  6. Why does tiny elf say not to level skills? Cuz you might get the attention of "d"/etc? Dragon dude didn't notice kumoko till she killed a dragon and isn't he a admin also? (even though he calls D a powerful god)
  7. How was Elf teacher able to remove homies skills/stats early on? is that explained?
  8. Kumoko is basically a psychopath right? thinks araba ripping apart snake is beautiful, when dragon reincarnation got kin eater, they were all freaking out, kumo was like "ohhh, title", she plays with bones and got used to eating monsters very fast (not that she had a choice) she was smiling when killing hero scene/etc
  9. Sophia is the baby we see end of show, but also the lady we saw go up to homie that thinks he owns the whole world, and she like recruited him? So him, her, and heros emotionless brother are on same "side"?
  10. Komoko sees "shouko negishi" as the vampire, amd she is confused by it, more from the like Japanese aspect of it and not that it's a former classmate? [in the anime she didn't mention remembering that name]
  11. When D talks to kumoko, d says 25 reincarnated and not 26, saying D didn't reincarnate, but kumoko did, so it should still be 26 right?
  12. If nightmare of the labyrinth kumoko was S rank already, her half human or full human form must be stupid high rank right?
  13. How moch of the demon lord, is actually her? Like kumoko (body brain) fused with her or whatever pretty hard, acting a lot like the kumoko we know.
  14. is body brain still in demon lord, eating her soul or whatever? (Making her more and more like kumoko)
