@Doodmandood :
I didn't knew how taming worked. Thanks for the clarification.
There is plenty of people who willingly restrict their own freedom if it means gaining something in exchange, see any people who signed a job's contract, I just thought it was something similar.
@Wildstag :
Home invasion is a crime but the punishment of this crime is really really rarely the execution of the criminal...
And they didn't wanted to burn her house down, that's one of the misunderstandings: They weren't "clearly breaking and entering", they were searching for her house and when one got trapped in one of her trap they ended up, unwillingly, burning her entire house.
And they didn't attacked her first. If you look at "chap 33.1 page 10" you can see they only draw their weapons and it's Kumo who attack first and kills them (unintentionally). It's worth noting that kumo has her aura that frighten other monster, aura which must work against human too.
So in the end :
- They didn't wanted to burn her house down.
- Maybe they didn't wanted to attack her and were just cautious or afraid of the spider because of her aura and the fact she was angered by her house burning down.
- Kumo didn't wanted to kill them at first.
So yeah, the first events which led to the human massacre were bad luck and misunderstanding.
Maybe they would have attacked her anyway, maybe Kumo would have killed them whatever they would have done. But in the end these three events weren't done willingly and were just a misunderstanding.
