I don’t think they’re mad because it’s edgy. They’re mad because it’s edgy for no good reason other than it just is. Yeah, the title outright says what’s going to happen, but it feels like this is just going to end up like a bad snuff film. I hate myself for saying this, but even Dungeon Seeker was more subtle than this. And yes, I’m talking about both the light novel and the manga.
As for your edit. No reasonable person would ever wipe out an entire race or species in pursuit of revenge or justice for the sins and on the orders of one single individual. That’s some holocaust school shooter logic. I’d be happy settling for all people responsible and making a list. This maniac wants all humans dead just because.
Like, how much of the MC’s character isn’t currently muh edge? We know nothing other than he reincarnated, was betrayed, and now calls for mass extermination of life at all costs. Not much personality other than a medium for the author to do as he pleases imo.
