man.. so many angry, lol
my only problem with this thing is the people that raised him, they look like human, call them spirit or whatever, imo, the thing will be more acceptable if he's raised by some bear monster or something.
These spirits pretty much act like human, and with their level of intelligence, this looks more like as racial hate between intelligent race. The monster (tree stump) really doesn't enter into the equation, mc was raised to hate human because the spirit hates them. This level of savagery matters when the group of people that raised MC seems to have intelligence (heck damn, they looks like to be living in an empire, has hierarchical society), and they took care of some random baby near the forest out of love, doesn't make sense when the mc was talking about the strong devours the weak logic here, because he should have died from beginning if that was the case. The spirit seems to have high level emotional capability and they've evn shown pity to this weak baby that was him. The structured social hierarchy and such can only be maintained if these spirits has equally complex moral compass like human, meaning they should be capable of diplomacy and communication, but here, our mc just slaughter the human like that.
Naturally one can argue that the MC already warned them and it's their retribution, but his ruthlessness doesn't fit with the implied love and care that was given when they were raising them.
Will be nice if author tells the story of his childhood, and will be even more interesting to see the stance between this spirit empire and humanity. Though, the way author wrote the beginning chap makes it seem that he leaned to making the humanity as bad civilization (stupid black hair cursed child whatever keklmao), humanity here was written like some uncivilized tribe.
