No let the humans live please. I want him to continue his murderous rampage until the last human is dead. I don't want him to rehumanize, or turn out like those other so called "revenge" series where they turn into normal japanese losers. No hope, no future, no revival bullshit, just unforgiving, complete rampage. So far, so good.
Author is a troll thought. Give MC hope, then continue to get the humans to murder the fuck out of his hope. Heh
