@Drey Dude, nobody is saying they aren't killers. What is being said is two things though: That the author goes out of their way to
humanize them and give them motivations so they aren't exactly conpletely flat. That from a writting standpoint is cool. You don't have to like the characters, that's fine.
The other thing is that NOBODY in the manga is entirely good either, not even the good guys that, as you pointed out, kinda don't give a shit either way as long as they don't touch their stuff. Part of the reason I suspect this is this way is because nobody in the damn manga is actually human (or right in the head, for that matter. Even Mihai seems to have suicidal tendences from living so long).
Kemono Jihen is clearly not a series with a black and white morality, far from it based on what we have seen so far. Is not like, idk, Kimetsu where we had clear heroes that acted the part and villians that had sad pasts almost always.
I guess at this point we are better off just focusing on the story and where these set of characters are gonna go rather than them being good enough for us to deem deserving to live. Personally I would laugh my ass off If Kaede survives because Akagi suicides for him (kinda like Hinata did for Robara). Mostly because I want to see people get pissy about it.
Both dying would do for me as well but uhh yeah I doubt they are making it alive.
